AT&T, Ericsson and Qualcomm Announce 5G NR Collaboration

Elena Neira
January04/ 2017

With CES 2017 underway, AT&T, Ericsson and Qualcomm are announcing plans to conduct interoperability testing and field trials of 5G New Radio (NR) starting  the second half of 2017. These tests will be conducted in  the mmWawe very-high frequency bands –short distance and high bandwidth. Cellular providers in general aim at utilizing these frequencies in “densification” efforts in high population areas and in high usage venues like football stadiums, train stations, concert halls and urban plazas. The most demanding use will be streaming video loads in 4k and/or HDR, connected cloud services and VR/AR apps.

 

The Trials and Interoperability Testing will Be Based on the Expected 5G NR Being Developed by 3GPP:   Ericsson, Qualcomm Technologies Inc., a subsidiary of Qualcomm Incorporated, and AT&T are saying that their plan is to conduct interoperability testing and over-the-air field trials based on the expected 5G New Radio (NR) specifications “being developed by 3GPP, which will form the basis of the global standards.” The trials intend to promote faster 5G deployment, and will be “based on standards-compliant 5G NR infrastructure and devices once 3GPP completes the first release of the official specifications, which is expected as part of Release 15″.  The interoperability testing and trials, which are planned to launch in the United States starting in the second half of 2017, are intended to track closely with the first 3GPP 5G NR specification that we expect to be part of Release 15 – the global 5G standard that is expected to make use of both sub-6 GHz and mmWave spectrum bands. Tracking the 3GPP specification is important because it promotes adherence and validation with the global 5G standard, accelerating the time to standard-compliant devices and infrastructure. Focusing on the 5G NR standards also should validate that the technology will work correctly with any future 3GPP 5G NR updates.”

 

The Trials will run over millimeter AT&T’s Wave (mmWave) in the 28GHz and 39GHz Bands:    The trials will showcase new 5G NR mmWave technologies that utilize wide bandwidths available at these higher frequency bands to increase network capacity and expect to achieve multi-gigabit per second data rates. These technologies will be important to meeting the increasing consumer connectivity requirements for emerging consumer mobile broadband experiences such as virtual reality, augmented reality and connected cloud services. Additionally, the proliferation of 5G NR mmWave technology can make it more cost-effective and easier for multi-gigabit Internet service to reach more homes and businesses.

 

The trials will Utilize Device and Basestation Prototypes from Qualcomm and Ericsson Respectively:   The trials will employ 3GPP 5G NR Multiple-Input Multiple-Output (MIMO) antenna technology with adaptive beamforming and beam tracking techniques to deliver robust and sustained mobile broadband communications at the higher frequency bands, including non-line-of-sight (NLOS) environments and device mobility. It will also make use of scalable OFDM-based waveforms and a new flexible framework design that are also expected to be part of the 5G NR specifications. The trials are expected to yield valuable insight into the unique challenges of integrating mmWave technologies into mobile networks and devices.

“The roadmap of 5G technologies is complex, and collaborations such as this are critical to ensuring timely deployment of 5G networks,” said Matt Grob, executive vice president and chief technology officer, Qualcomm Technologies, Inc. “The 3GPP-based trials we are planning with AT&T and Ericsson will help us accelerate integration of advanced 5G New Radio technologies in form-factor accurate devices, building upon our long history of 3G and 4G LTE leadership and paving the path to wide-scale 5G deployments.”

“5G technology comes with new challenges, but more importantly, it offers tremendous opportunity to revolutionize the way we use mobile networks across industries,” said Tom Keathley, senior vice president, wireless network architecture and design, AT&T. “We’re tackling these challenges head-on through testing in our labs and field trials. We look forward to working with Ericsson and Qualcomm on these standards-based trials as we continue to accelerate standards efforts and move down our 5G evolution path.”

“5G is the greatest opportunity our industry has ever experienced. It will provide a platform for operators to address new markets, such as media, transportation and manufacturing,” said Ulf Ewaldsson, senior vice president and chief technology officer, Ericsson. “This important 5G standard-based trial collaboration will demonstrate compliance to 3GPP and support the accelerated commercialization of the global 3GPP 5G standard. Ericsson continuously works with leading operators and ecosystem players in 5G to enable global scale and drive the industry in one common direction.”

Elena Neira
January01/ 2017

As you might know, 2016 was our start-up year. And we are celebrating that it’s coming to an end by sharing with you the top 10 most popular articles of the year. In case you missed these, do give them a read, and let us know if you do not see any of your favorites in the list.

Happy New Year & Best Wishes for Peace, Tolerance, Wisdom and a Better World in 2017!

Here is the top 10 list:

  1. The Future of Spectrum Sharing with Machine Learning
  2. Facebook Adds Voyager, OpenCellular Specs, New Members to TiP
  3. Pokémon GO is the Biggest Mobile Game Ever
  4. Wearable Technology is In Style
  5. 5G Evolution or Revolution?
  6. How Much will 5G Data Cost?
  7. Inaugural Issue of 5G Magazine
  8. Why SoftBank Bought ARM Holdings
  9. Whitebox Switches Near Primetime
  10. World’s Cheapest Smartphone Meets Fastest Growing Market

 

Here are the articles with an introduction:

#1 The Future of Spectrum Sharing with Machine Learning: DARPA sees artificial intelligence’s machine learning enabling on-the-fly sharing of spectrum at “machine” timescales. It is announcing a 3-year competition, starting in 2017, to identify the best collaborative – not competitive – noble ways to manage spectrum beyond current band assignments and static allocation schemes.

#2 Facebook Adds Voyager, OpenCellular Specs, New Members to TiP: Facebook’s Telecom Infra Project (TIP) had its first summit in California, and the results are impressive: The introduction of Voyager, the availability of full OpenCellular specs. the addition of new members, and the establishment of  TIP Ecosystem Acceleration Centers around the world. With this, Facebook efforts to transform the telecommunications industry with an OCP  data center like approach continue at brisk pace

#3 PokemonGo is the Biggest Mobile Game Ever:  With more daily users than Twitter and bigger engagement than Facebook in under one month, Pokémon GO is a viral phenomenon with unprecedented  growth at global scale. It launched in the US and just 10 days after this augmented-reality multi-player mobile game app reached the same active users that Twitter reached in 10 years. Let’s look at this and record-breaking numbers -users, engagement, market cap- as well as companies and technologies behind it, and the impact in the future of mobile and 5G.

#4 Wearable Technology is In Style:   Wearable technology is on the rise in both personal and business use. In the consumer space, sales of smart wristbands started accelerating in 2013. Smartwatches are a second high-profile sector and while wearable devices have been around for years, it has only started gaining mass market attention with the introduction of new models by Samsung and later by Apple.

#5 5G Evolution or Revolution?   The major 5G developments of the month come via Far EasTone’s 5G services demo supported over 4G networks evolving to 5G, via iconic device launches from Apple and Samsung whose new features predict an evolution to 5G, and also via news from CTIA 2016 SuperMobility introducing 5G products and solutions as evolution from exiting solutions, just faster, better performing, cheaper and/or more optimized. The common theme in these developments is that they position 5G as “evolution” of 4G. However, in previous months we saw developments that position 5G as a “revolutionary” approach such as Facebook’s TIP, Spectrum Sharing from DARPA, and Cloud, Open Source Telco. For now, both approaches are present in the marketplace. At the end, will 5G be an evolution or a revolution?

#6 How Much will 5G Data Cost?  Enabling 5G data-hungry streaming apps like virtual reality, 360 video, and augmented worlds means delivery big volumes of data to our smartphones. Even Today a single video stream needs from 0.3 GB per hour for low resolution, and up to 7 GB per hour for Ultra HD. If multiple streams, multiple devices, 24/7 service and billions of user are to be served, then the feasibility of 5G rests largely on the infrastructure to deliver cost-effectively these large volumes of data

#7 Inaugural Issue of 5G Magazine:  5G speed records of 9.83 Gbps and 20 Gbps from China and Europe, respectably; the OpenCellular platform to disrupt radio access; a White House backed $400 Million initiative for advanced wireless research; new, innovative, open hardware for IoT and wearable chips; OpenCellular project announcement; spectrum allocations in US and UK from regulators FCC and OFCOM; and Pokemon Go is now the largest mobile app, ever!   These are all major mobile industry moves in the last few days. We are in the middle of the Summer but no one in the mobile industry seems to be taking vacation. We are not on vacation either but working day and night to put together this first issue of the 5G Magazine.

#8 Why SoftBank Bought ARM Holdings:   SoftBank’s CEO Masayoshi Son spent the last weeks selling his important holdings in China’s Alibaba, Japan’s GungHo, and Finnish’s Supercell to buy UK based ARM Holdings (ARM) for $34 B. Read this as indicative that a semiconductor IP block company is as strategic as internet, mobile, e-commerce and game companies for the SoftBank Group.

#9 Whitebox Switches Near Primetime:    White box switches are, in theory, simple to realize with merchant silicon and SDN. These two ingredients have been available for years, and there are plenty of them. Despite this situation, most in the industry agree that the availability of white box switches has been limited, and limited too has been the use of these white boxes. Will this situation continue or is it about to change?

#10 World’s Cheapest Smartphone Meets Fastest Growing Market:   Last month’s news that a smartphone with a $4 promotional price tag ($6-7 after) was about to be released in India created country-wide expectation, and made news around the World. At the time of this writing, the $4 smartphone – the Freedom 215- has not been realized as originally planned but lessons learned are worth noting specially for those looking at connecting the next unconnected 1 billion mobile subscribers, perhaps with cost-effective 5G technology. For now, this is what we saw happening when the world’s cheapest smartphone met the fastest growing mobile market: On the market side, it proved the huge appetite for low-cost mobile devices in developing economies; on the business side, it proved that if you lower the price of a smartphone from $600 (approximately the price of the iPhone in India) to $6, you can get overnight a 75 million order. There is no device maker in the world that could fulfill that order. Even the giants (Apple, Samsung, Huawei,…) would take months, could be close to a year to complete the order.

US Cellular 5G Trial in 15 GHz Reaches 9 Gbps

U.S. Cellular and Ericsson are reporting successful completion of  5G testing in the 15 GHz spectrum band which achieved peak throughput of 9 Gbps at a distance of 787 ft. (aprox. 240 meters) to bring the next-generation mobile network technology one step closer to deployment. Using this 15 GHz band, Ericsson installed 5G radios on a tower currently in commercial service. The over-the-air test was possible using an experimental FCC license. It run under varying environmental conditions to simulate real world use.  The tests evaluated a number of new radio access (NX) carrier combinations to verify network throughput and performance benchmarks. The trials achieved peak throughput of 1.5Gbps at a distance of one mile and 9Gbps at a distance of 787 ft. The tests also included radio resource sharing, beamforming, beam tracking, peak throughput and multi-user MIMO tests. Michael S. Irizarry, Executive Vice President and Chief Technology Officer, U.S. Cellular,says: “This latest trial with Ericsson demonstrates incredible 9Gbps speeds in an environment that was close to a real world scenario, and we look forward to collaborating with Ericsson on the development of standards for a healthy 5G ecosystem. We are committed to giving our customers the best experience with the latest technology that can enhance their lives or businesses, and a fast, high-quality network that works whenever and wherever they need it.”

Spectrum Sharing in Focus at NTIA

US NTIA Assistance Secretary Strickling delivers a ‘5G Wireless Future and the Role of the Federal Government’ remarks focusing on spectrum sharing efforts at the agency. He says that  growth and innovation in the wireless sector will hinge in large part on the successful introduction of 5G networks and the ability to deliver the spectrum needed to power this and future generations of mobile technologies. More often than not, this spectrum has already being assigned to specific users such as the military and needs to be repurposed. From the outset, it has been clear to NTIA that in repurposing spectrum, the old method of clearing spectrum of federal users and then making it available for the exclusive use of commercial providers was no longer sustainable. Among new techniques that the agency has used is the “fast-track” which consists of a process to examine bands on an expedited basis as it was done for the AWS-3 auction and the FCC’s proceeding to quickly establish the Citizens Broadband Radio Service (CBRS) in the 3.5 GHz band. Beyond this example, NTIA’s strategy has been leading a fundamental shift in spectrum management that promotes and advances spectrum sharing among all users as  a vital path forward to meeting the growing demand for additional spectrum for wireless technologies. Specifically affecting 5G networks, the NTIA has been looking at leveraging duplexing and spectrum usage schemes to promote co-existence of 5G federal and non-federal systems, and is also working on a more transparent and consistent process for determining interference criteria for effective sharing of spectrum. In closing remarks, Strickling also mentions that NTIA recognizes the need to more accurately quantify current spectrum demand, usage and projections of future requirements. “How granular does coverage need to be for emerging 5G applications? For IoT specifically? How important is reliability in an IoT environment? These are questions that will need to be considered in weighing future spectrum policy decisions.”

ITU Completes Wireline Enablers for 5G Study

One of ITU’s IMT-2020/5G related activities in the last couple of years has been to host in ITU-R a preliminary study group looking into the networking innovations required to achieve the performance targets of 5G. The group met for a final time last December 7 to present their conclusions which highlighted as key themes new architecture, FMC (fixed-mobile convergence), network softwarization, and fronthaul/backhaul. As far as new architecture, a 3GPP-led core network evolution study showed 4 reference points important for the core: NG2 (reference point for the control plane between NextGen RAN and NextGen Core), NG3 (reference point for the user plane between NextGen RAN and NextGen Core), NG1 (reference point for the control plane between NextGen UE and NextGen Core), and NG6 (reference point between the NextGen Core and the data network). As far as FMC, it concluded that the approach has challenges like a lack of coherence among various protocols, lack of coherence among 4G, 5G, WLAN, Fixed BB Protocols, also a lack of coherence between user and control planes; in addition, a lack of coherence among identification types of different access technologies like (1)  cellphone number for 4G/5G wireless access, (2) broadband ID for Fixed BB access, and (3) WLAN ID for WLAN access. As far as fronthaul/backhaul, Ethernet was the most talked about technology with both ROE (Radio Over Ethernet) and X-Ethernet presented solutions. As far as network softwarization, slicing and orchestration were big topics shown in several presentations including ETRI’s full system 28 GHz 5G proof-of-concepts at 2018 Winter Olympic Games.  The study group’s output takes the form of five draft ITU international standards and four draft ITU technical reports to drive related work in ITU’s standardization expert groups.

Elena Neira
December16/ 2016

U.S. Cellular and Ericsson are reporting successful completion of  5G testing. Both highlight that the test was conducted using the 15 GHz spectrum band, and it achieved peak throughput of 9 Gbps at a distance of 787 ft. (aprox. 240 meters) to bring the next-generation mobile network technology one step closer to deployment.

The Choice of the 15 GHz Band to Test 5G:  The figure above depicts the bands available worldwide for microwave deployments, and 15 GHz band the biggest frequency band of all. This is not because 15 GHz has the widest spectrum, but more because it is widely used all over the world. Using this 15 GHz band, Ericsson installed 5G radios on a tower currently in commercial service. The over-the-air test was possible using an experimental license from the Federal Communications Commission (FCC) and run under varying environmental conditions to simulate real world use.

Network Coding for 5G Virtualization

Elena Neira
December15/ 2016

MIT, in collaboration with other research centers and with industry, is looking at a new approach to virtualization in 5G that combines Software Defined Networks (SDN) ,Network Function Virtualization (NFV), Content Centric Networks (CCN), WebRTC, wireless mesh networks, Multicast, and such with a technology called Network Coding.

 

From Store-and-Forward to Store-Code-Forward in the Network:   Network Coding (NC) is a new paradigm that breaks from the store–and–forward approach currently used in communications networks. NC allows intermediate nodes in the network to recode incoming data packets with a new store–code–forward paradigm. This ability to code within the network contrasts with traditional end-to-end erasure correcting codes such as Reed-Solomon, LT codes, and Raptor codes, and gives networks the ability to generate redundant packets where they are needed instead of injecting them end–to–end as other erasure codes would do.  By doing this, NC enables coding strategies that adapt to the dynamics and topology of the system and even to features specific to end devices. This is very beneficial, for example, while transporting streaming video over heterogeneous networks to a variety of end devices.

Applications and Requirements of Network Coding:   Research indicates that applying these new coding algorithms to the network has the potential to increase throughput and robustness, to reduce storage requirements, to shorten latencies, and to reduce energy consumption in networks. However, different apps and services present different networking requirements, and network coding does not address all of them; even when it does, the encoding and decoding algorithms need to be carefully adapted to the specific problem at hand. For example, the coding algorithms require to be adapted to he constraints imposed by a wide range of devices (core network routers, smart phones, embedded sensors and such) whose available memory and computing power may differ by several orders of magnitude. It is worth pointing out that network coding operations may be speed up substantially through the use of specialized hardware, as evidenced by the successful implementation of network coding on Graphics Processing Units (GPUs). So far, practical network coding algorithms have been identified for data gathering in sensor networks, routing in wireless mesh networks, peer-to-peer networking and content distribution, and streaming applications.

An Open Source Prototype of Network Coding:   This new Network Coding paradigm would require redesign of network protocols, and researchers have already started looking at practical implementation aspects of adding network codes to the future Internet and to 5G networks and tools. There is already a real-world prototype that uses open source OpenStack and OpenFlow on the SDN side, and the Kodo Library on the NC side. The prototype shows NC’s capabilities to mask packet losses in the network on single and multi path transmissions. Comparing the results to standard TCP and Multi–Path TCP (MPTCP) as specified by IETF, it indicates that 3 to 11 fold gains are attainable in terms of throughput and reliability even with moderate losses on single–hop, multi–hop, and multi–path scenarios.

AT&T with Ericsson & Intel Trials 5G Enterprise Markets

AT&T has launched what it calls a 5G business customer trial. It is partnering with Intel, which is hosting the trial in one of their offices in Austin, and with Ericsson. AT&T is saying that the trial delivers more than a gigabit per second bandwidth, enabling Internet access, VPN, Unified Communications apps and 4K HD video streaming. The ultimate goal is to look at future enterprise use cases of 5G VoIP in the 15GHz and 28GHz spectrum bands to validate how millimeter wave (mmWave) powers a 5G network experience. The trial builds upon a prior first public 5G demo featuring streaming 4K HD video, real-time camera feeds and reaching speeds of nearly 14 Gbps conducted with Ericsson. Now, AT&T is taking that demo and exploring what benefits it can provide to real-world business customers. “The future of video is mobile. And the future of mobile is video,” said Tom Keathley, senior vice president, wireless network architecture and design, AT&T. “Mobile video streaming continues to be a vital aspect of our 5G work, and this trial gives us an opportunity to test 4K HD video streaming across further physical distances between pieces of equipment. With our 5G and 4G LTE advancements, we expect speeds rivaling what we see from cable providers. Our path to 5G will help make this vision a reality faster.”

AR, VR & 3-D Video CordCutting with WiFi, LTE Today, with 5G Tomorrow

Today’s AR, VR and 3-D Video experiences are largely tight to fixed platforms like consoles, TVs and PCs. However these experiences are migrating to mobile platforms to provide mobile experiences like AR game PokemonGo. Startup Visbit is one of the companies that during the VRX Conference (December 8-9, 2016, San Francisco) was showcasing 3D-Video, VR and AR experiences in mobile platforms. The company said that they already stream 4K HD and 3D-Video to mobile devices over WiFi and LTE with “near zero latency” and they achieve this with focus on managing view-switch latency. This type of latency is defined in the context of 3D Video foveated streaming/rendering. Both Oculus Dynamic Streaming and Visbit “View Optimized Streaming” belong to foveated streaming. In foveated streaming, the visible section of a 360º video is streamed in high resolution, and the non-visible section in low resolution. If the user turns the head, that low resolution stream is switched to high resolution.
For immersive mobile AR,VR and 3D-Video streaming in real-time as envisioned in some 5G use cases, additional type of latencies need to be considered, and the most important is Motion-to-Photon. This latency refers to the time it takes an image to match the movement of a user. Ideally, this time would be 0 msec. for a flawless user experience, in reality Today’s mobile platforms aim at approximately 16 msec. To move this number closer to the ideal 0 msec., device, content delivery (video player streaming the content) and network platforms need readiness. Visbit’s LTE capability shows great progress towards realizing this readiness in 5G.

Virtualization in 5G with Network Coding 

MIT is looking at a new approach to virtualization that combines Software Defined Networks (SDN) ,Network Function Virtualization (NFV), Content Centric Networks (CCN), WebRTC, wireless mesh networks, reliable Multicast, and many more with a new technology called Network Coding (NC) for 5G. NC is a new paradigm that breaks from the store–and–forward approach currently used in communications networks. NC allows intermediate nodes in the network to recode incoming data packets, thus providing a store–code–forward paradigm. This ability to code within the network contrasts with traditional end-to-end erasure correcting codes such as Reed-Solomon, LT codes, and Raptor codes, and gives networks the ability to generate redundant packets where they are needed instead of injecting them end–to–end as other erasure codes would do.

This new Network Coding paradigm would require redesign of network protocols, and researchers have already started looking at practical implementation aspects of adding network codes to the future Internet and 5G network protocols and tools. There is already a real-world prototype that uses OpenStack and OpenFlow on the SDN side, and the Kodo Library on the NC side. The prototype shows NC’s capabilities to mask packet losses in the network on single and multi path transmissions. Comparing the results to standard TCP and Multi–Path TCP (MPTCP) as specified by IETF, it shows attainable 3 to 11 fold gains in terms of throughput and reliability even with moderate losses on single–hop, multi–hop, and multi–path scenarios.

5G mmWave 60 GHz Link Reaches up to 800 Meters

University of California San Diego is announcing the world’s longest bidirectional phased-array link in the 60 GHz band. At a link distance of 300 m, the 32-element array achieved 2 Gbps over all scan angles up to ±45 degrees. Data rates were 4 Gbps at 100 m and 500 Mbps at 800 m over most scan angles. A leading wireless operator is suggesting the system can deliver content to eight homes at a time at up to 300 m. The entire phased array consumed just 3-4 Watts of DC power due to the high-performance system-on-a-chip (SoC) designs UC San Diego created using the third-generation silicon germanium BiCMOS. “This is the second time UC San Diego has worked with Keysight to demonstrate high-performing phased-array 5G communication links, now achieving gigabit-per-second speeds at previously unimagined ranges and with extremely low power consumption,” said Gabriel M. Rebeiz, member of the U.S. National Academy of Engineering, distinguished professor and wireless communications industry chair at the UC San Diego Jacobs School of Engineering.

Korea Brings Telco and Mobile AR/VR Firms to Develop 5G Apps

South Korea’s Ministry of Science, ICT and Future Planning is leading the Giga Korea project that aims at creating a 5G ecosystem in the country. The vision is to use 5G connectivity as enabler of future services such as connected car, mobile robotics, and immersive media based on augmented reality and virtual reality technologies. SK Telecom, a major stakeholder in Giga Korea, is partnering with these three local startups to develop virtual reality (VR) and augmented reality (AR) devices to use with 5G connectivity:

  • Redbird, a developer of state-of-the art 3-D scanning and web viewer services;
  • Looxid Labs, which measures various biometrics including eye movement and brainwave signals using a VR headset to analyze the user’s cognitive ability and emotional status; and
  • Elrois, which synthesizes videos clips shot with drones with 3-D graphic images to help provide highly realistic game-playing experience.

SK Telecom said prototypes of the services will be available by the first half of 2017 and it will assess their potential as actual businesses then. “We aim to come up with successful business models by joining hands with smaller yet promising companies to innovate platforms and create a 5G service ecosystem at the same time,” said Choi Jin-sung, SK Telecom’s CTO and head of corporate R&D center. SK Telecom, Korea’s No. 1 operator, has recently unveiled plans to deploy and operate 5G trial networks in Seoul and several other metropolitan areas in cooperation with global telecommunications equipment manufacturers including Ericsson, Nokia and Samsung Electronics starting early next year.

Cellular Networks without Cells

Today’s cellular networks are based on hierarchical cellular topologies where with the coverage area divided into cells. But new cell-free Massive MIMO technology is challenging this assumption for 5G. From the technical point of view, Cell-Free Massive MIMO is a new version of Network MIMO (cooperative multipoint joint processing) that takes advantage of favorable propagation and channel hardening properties. From the architecture/deployment perspective, it consists of a large number of distributed access points (APs) which simultaneously serve a much smaller number of users over the same time/frequency resources based on directly measured channel characteristics. In Cell-Free Massive MIMO, APs and users have only one antenna which uses specific algorithms for channel state, power control and pilot assignment.

From the market point of view, Cell-Free Massive MIMO considerably improves performance with respect to a conventional small-cell deployments. By serving each user with a dedicated AP, it delivers 5 to 10 fold per-user throughput improvements. This technology is still at the early stages of development, it is part of Europe’s H2020, and a candidate become part of 5G with Ericsson being one of the key contributors in to the program.

LG Electronics, Yonsei University Demo Full Duplex MIMO

LG Electronics and Yonsei University have co-developed and successfully trialed a 80 MHz bandwidth Multiple Input Multiple Output (MIMO) based full duplex technology increasing efficiency of frequency by up to two times compared to time division duplex (TDD). TDD sets different times for upload and download in the same frequency, while frequency division duplex (FDR) allocates different frequencies for upload and download. The report highlights that LG Electronics is developing not only the FDR antenna but also the ‘digital antenna technology’ required to realize full duplex radio in one system i.e., a MIMO FDR transceiver which will pave the way for ease of integration by OEMs in their 5G radio access products. FDR is expected to be particularly effective boosting capacity in sub-6 GHz FDD bands where the available bandwidth is limited.

China Confirms 5G Network Built-Out Plan for 2019 with $73B Budget 

China aims at realizing 5G commercial service as early as 2020 with the backing of its regulatory body as well as the backing of business plans at several local and global companies. Insiders from IMT-2020(5G) promotion group, which is dedicated to supporting and promoting  5G technology, said that the planned second-phase of technology testing will commence in 2017 as scheduled. The promotion group also disclosed that the experimental stage of 5G will last three years, from 2016 to 2018. Finally the group said that the construction of a 5G network in China will begin in 2019, and it will have a total dedicated budget of $73B.

Sources at China Mobile Research Institute (deputy general manager Mr. Yuhong) said that the three biggest mobile operators in China are already working with OEMs for testing, and added that the first 5G standard will be announced in 2018. On the services and applications area, IMT-2020 5G promotion group is hosting 42 local companies that collaborate at the 5G Joint Innovation Center to research and develop IoT, connected cars, industrial Internet and other verticals. Reportedly some of their projects are close to entering commercial operation phase, ready to be tested.

EU Weights on 5G Intellectual Property and Licensing

During a conference in Belgium, EU Commissioner Vestager offered some remarks about the licensing and patent situation in the mobile sector. The Commissioner cited a recent study findings that $120 of the total cost of every smartphone goes to patent royalties. There were also references to patents essential to a standard and how for some OEMs it “could mean they end up paying unjustified royalties, and their customers have to pay more…” thus the need of a working framework where patent holders usually have to commit to making their technology available on fair terms. These remarks serve as a reminder of the many outstanding licensing and patent issues around 5G. In the past, the EU Commission has shown to favor certain improvements to enable easy and fair access to standards essential patents specially in the 5G IoT area which involves the convergence of many complex technologies. Among others, enhancements in transparency of access to reliable information on standards patent holders, patent scope, and standard essential patent declarations. The Commission has also been positive to facilitating efficient patent disputes to help remove commercial and legal uncertainty for smaller companies. The Commission intends to work with standard development organisations, patent offices, industry and the research community to clarify licensing principles.

DeutscheTelekom Demos 5G Network Slicing

Deutsche Telekom and Huawei report completing an autonomous E2E demo of dynamic real-time slicing of the 5G Radio Access network, the Data Center (DC), and the transport network. E2E network slicing is seeing as enabler of 5G services. It is an integral part of the 5G architecture where network classes such as Enhanced Mobile Broadband (eMBB), massive Machine Type Communication (mMTC), Ultra-Reliable Low-Latency Communication (uRLLC) are ‘logical network’ slices of a unified physical network infrastructure. The demo conducted in DT’s lab in Bonn, Germany implements bandwidth based transport network slicing. The transport network consists of TSDN controllers and DWDM nodes. The controllers generate a series of specific data forwarding paths based on slice topology and service requirements. At radio level, the F-OFDM air interface technology is the key to the spectral granularity and also permits efficient co-existence and isolation of all 5G New Radio (5G NR) slices. In the demo, real-time dynamic adjustments of network slices on very fine spectral granularity, signal process and protocol stack were validated. The automatic implementation is possible with Service Oriented Network Auto Creation that uses software-defined topology, software defined protocol and software-defined resource allocation to ensure the automatic implementation of slice management, service deployment, resource scheduling, and fault recovery based strictly on a detailed and thorough network data analysis.

A 500 Massive-Element Antenna to Power 5G

Elena Neira
November28/ 2016

A prototype 500 massive-element active antenna system (AAS) targeting 5G in the 28GHz band was just announced by Japan’s NEC. NEC says that the prototype is capable of achieving 1 kilometer distance communications in 16 directions, at a speed of 30 Gbps or faster per cell achieving a spectral efficiency 20 times greater than LTE with low power consumption.

 

mmWawe and 5G, a Marriage Made in Heaven?:    With the requirement in mind that 5G mobile networks are to provide multi-gigabit communication services such as HD video, it seems but natural to look at mmWave spectrum where bandwidth is plentiful. Currently the mmWave bands that the industry is looking at are the 28 GHz band, the 38 GHz band, the 60 GHz band, and the E-band (71–76 GHz and 81–86 GHz). Due to the fundamental differences between mmWave communications and existing other communication systems operating in the microwaves band (e.g., 2.4 GHz and 5 GHz), there are many challenges in physical (PHY) layer, medium access control (MAC) layer, and routing/network layers.

The Challenge of mmWaves in 5G:   The high propagation loss, directivity, sensitivity to blockage, and dynamics of a mobile mmWave channel require new thoughts and insights into the architectures and the protocols to cope with these challenges. The major ones are to cope with unfavorable propagation conditions such as large path loss in LoS (Line of Sight) / NLoS (Non Line of Sight), signal blockage due to atmospheric absorption, and blocking objects attenuation and mobility. In addition, these challenges should be overcome in a cost and energy effective manner.

Technology Solutions to mmWave work for 5G:  The widely accepted solution is adaptive beamforming equipped with very large antenna arrays. The combination of these two technologies meets the following objectives:

  • Adaptive beamforming in different propagation conditions, NLoS/LoS in the presence of mobility
  • Support for multiple users
  • Robustness against signal blocking
  • High data rates and low-latencies
  • Robust hardware capable of high frequencies and ultra wide bandwidths

NEC AAS for 5G

 

NEC’s Adaptive Antenna Array:   NEC’s 500 elements Active Antenna System (AAS) acts as the front end for basestations that support the 28GHz band, and meets the requirements of 5G. NEC has conducted simulation trials of its newly developed AAS with beamforming technology for transmitting radio waves in multiple directions (to objects) while intensively and simultaneously using many antenna elements. NEC reports achieving up to one kilometer in long-distance communication in 16 respective directions, at a speed of 30Gbps or faster per cell, in the 28 GHz band, and achieving a spectral efficiency 20 times greater than LTE.

In addition, original NEC reports saving several dozen watts of power and reducing the size by approximately 50%. In addition, “NEC has achieved the creation of a power-saving and compact-size AAS by leveraging circuit design technologies such as component mounting and heat radiation, which it has accumulated over the years through the development of microwave communication systems on high frequency bands.”

Internet Roadmap to 5G at IETF 97

Elena Neira
November27/ 2016

Network slicing, mobile edge computing, machine learning, and LPWA are the high profile 5G related use cases that IETF is looking at to enable the next generation of mobile communication systems. A redesign and/or evolution of the internet protocol (IP) could be needed to meet the requirements of these use cases, and during its November 2016 meeting (IETF97) different threads of work and initiatives took place to kick off design and/or prepare specifications. The IETF is doing the 5G work under different groups. The most relevant outcomes and discussion are a new 5Gangip special group looking at the needs of fixed and mobile next generation 5G protocols; the nmlgr Group looking at applying machine learning for 5G at network level; the first network slicing draft; and ETSI’s  MEC (Mobile Edge Computing) training introduction.

 

5Gangip Takes on 5G Mobile & Fixed Requirements:  This is a special group in IETF has the task to analyze the overall implications of the upcoming 5G (fixed and) Mobile communication systems on IP protocols. The group is at an early stage of discussion. At IETF97, they put together the IP issues document presenting “open and upcoming issues with upcoming new communication systems denoted as 5G aiming  to set a basis for documenting problem space, use-cases, and potential solutions related to next-generation network infrastructure.  The draft reviews currently investigated topics, including both inputs from IETF and from other SDOs as well as research activities.  The draft appears to focus on a simplified layering model for next generation IP, and it is in affinity with other efforts such as Identity-Location separation ILNP (Identifier-Locator Network Protocol published as RFCs 6740-6748); it also appears aligned with NSF (National Science Foundation) backed “mobility first” proposal of a global name resolution service (GNRS), and a Generalized Storage-Aware Routing (GSTAR) scheme to address core network level congestion.

Distributed Mobility Anchoring To Meet Diverse Mobility Needs of 5G and Beyond:  IETF’s DMM Group made progress on Distributed Mobility Anchoring which covers how multiple anchors and nodes with mobility functions work together to provide IP mobility support. It says that a “network or network slice may be configured with distributed mobility anchoring depending on the needs of mobility support.  In the distributed mobility anchoring environment, multiple anchors are available for mid-session switching of an IP prefix anchor.  Without an ongoing session, i.e., no IP session continuity required, a flow of a mobile node can be re-started using a new IP prefix which is allocated from a new network of the mobile node and is therefore anchored to the new network.  With an ongoing session, the anchoring of the prior IP prefix may be relocated to the new network to enable IP session continuity.

 

Network Machine Learning Proposed Research Group: The proposed Machine Learning (ML) group aims at defining this techniques in the network domain. Service clarification for 5G networks and Intelligent (ML) Defined Networks (IDN) which was presented by Huawei. So far the group has produced a draft document introducing background information of machine learning, then exploring “the potential of machine learning techniques for networks.  This document is serving as a white paper of the (proposed) IRTF Network Machine Learning Research Group.”

 

IETF’s Networking Group Prepares Network Slicing Draft:   The concept  “Network Slicing” is widely discussed and considered as the key mechanism to meet the diverse service requirements concurrently with the same physical network infrastructure.  This network slicing draft provides an overview of the concept “network slicing” in the current IMT-2020 (a.k.a. 5G) related works, and discusses the corresponding requirements on IP/MPLS network, which will be used as the mobile transport network for 5G.

 

Low Power IoT Networking Standards: LPWA The other group with activity related to 5G is the LPWA group whose work is just starting following the approved BoF at the previous IETF in Berlin. The group aims to develop wireless protocols to connect battery-powered devices over significant distances using license exempt bands thus not oriented to cellular system. Overall the work of this group is necessary to enable a variety of IoT applications, For now their scope is to in their scope the group to produce a standards for fragmentation of a CoAP/UDP/IPv6 packet over LPWA networks, and some of this work could in the future be applicable to 5G IoT.

Mobile Edge Computing Presented at IETF97

 

Training Session on Mobile Edge Computing (MEC):     ETSI delivered a training presentation during IETF97 diving into howMEC helps satisfying the demanding requirements for the 5G era in terms of expected throughput, latency, scalability and automation; it also offers additional privacy and security and ensures significant cost savings. Many of the use cases can be deployed with Mobile Edge Computing prior to 5G thus MEC is not specific but many of its features are enablers of 5G via the MEC and Platform APIs.

November21/ 2016

Facebook CEO Mark Zuckerberg and his Connectivity Lab team announce a new point-to-point wireless transmission record of 20 Gbps in a 13 Km point-to-point link, with a spectral efficiency of 9.8 bps/hz, using the same amount of power it takes to light a single lightbulb. DoCoMo reports groundbreaking results in two of its 5G trials; one trial with Samsung’s 28 GHz equipment delivering 2.5 Gbps to a device moving in a train at 150 km/h; and the other trial with Huawei’s 4.5 GHz equipment delivering an spectral efficiency of 79.82 bps/hz/cell. Qualcomm announces a new 5G NR Spectrum Sharing testbed with LBT (Listen Before Talk) capabilities. Telefónica says that Huawei’s 5G UCNC PoC delivers 233% more per-cell connections, 78% reduction in signaling overhead, and 95% lower latency than state-of the-art LTE. Last but not least, the work to make the Internet 5G-ready during the IETF97 meeting.

Telefónica and Huawei UCNC PoC Results in 5G Connections Per Cell Up 233%, Signaling Down 78%

Telefónica and Huawei have been testing CloudRAN UCNC (User Centric No Cell) with a hyper-cell network architecture that enables the large-area coordination of many base station nodes to eliminate handovers between cells and reduce interference from adjacent cells. UCNC reduces the over-the-air protocol signaling overhead and the access protocol latency, as well as increase the number of air-interface connection links. According to the results of PoC tests conducted at Telefónica-Huawei 5G joint lab, the number of 5G connections per cell increased by 233%, the signaling overhead decreased by 78%, and the latency decreased by 95% compared with state-of the-art LTE.

UCNC also defines the “ECO State” as a new device protocol state for sending short packets directly without the need of over-the-air signaling, thus making users be truly “always connected”. Another key technology is “SCMA-based Grant Free Access” to simplify uplink access procedures to reduce latency and increase the number of connected devices. In the next phase of the UCNC PoC, Telefónica and Huawei will target to enhance the cell edge spectral efficiency, in order to avoid end-user experience degradation at the cell edges and network service disruptions.

Facebook Connectivity Lab as well as Mark Zuckerberg himself announced achieving 20 Gbps over 13 km in a P2P mmWave link using the same amount of power to light a single lightbulb of 105 DC Watts. The transmission used a bandwidth of 2 GHz, resulting in an overall spectral efficiency of 9.8 bps/Hz. Soon this technology will make it into Facebook’s solar-powered planes to beam internet access to areas of the world that aren’t connected. In general, Facebook’s Connectivity Lab sees it to be applicable to a number of solutions they are working on. Ford example, it could be used as a terrestrial backhaul network to support access solutions like OpenCellular, or as a reliable backup to free space optical solutions such as the laser communications gimbal and optical detector in case of fog and clouds. Ultimately, the point-to-point mmWave link is expected to serve as the connection between a ground station and Aquila, our solar powered UAV.

The next generation air-to-ground communication system capable of supporting 40 Gbps each on uplink and downlink between an aircraft and a ground station will be flight-tested in early 2017. Facebook will continue to push the limits of wireless capacity over long ranges while staying within the tough size, weight and power requirements of Aquila communication payloads.

Docomo New 5G Trials in 4.5 GHz and 28 GHz

DoCoMo reports groundbreaking results from two separate trials in the 4.5 GHz and the 28 GHz frequency bands. In the 28 GHz mmWave and as part of a joint trial with Samsung, DoCoMo reports achieving a data speed of over 2.5Gbps with a mobile device traveling at 150 km/h in a train. To date, no test had achieved a successful wireless data transmission to a fast-moving device due to the large path-loss of high-frequency radio signals using mmWave frequencies. In this trial, the problem was resolved with the use of massive MIMO with beamforming and beam tracking. In a separate trial, DOCOMO and Huawei report results of an outdoor trial using the 4.5 GHz frequency band in a 100,000 square-meter field. The trial combined multi-user MIMO (MU-MIMO) technology for simultaneous multiple access and a precoding algorithm that optimizes signals for maximized performance and limits inter-user interference. It achieved a MU-MIMO transmission of a maximum 79.82 bps/hz/cell, which was reportedly 1.8 times better than in the November 2015 outdoor trial conducted in China.

Internet Roadmap to 5G and Beyond Out of IETF97

Network slicing, mobile edge computing, ultra-low latency, machine learning and massive IoT are among the 5G related use cases that IETF is looking to support in next generation mobile communications. A redesign and/or evolution of the internet protocol could be needed to meet the requirements of these use cases, and during its November 2016 meeting (IETF97) different threads of work and initiatives took place to discuss and prepare specifications. The most relevant are a new 5Gangip special group looking at the needs of fixed and mobile next generation 5G systems, the nmlgr group looking at applying machine learning 5G at network level, the first network slicing draft, and the introduction MEC (Mobile Edge Computing) presented by ETSI.

Groundbreaking Results in DoCoMo 5G Trials with Huawei and Samsung

Elena Neira
November20/ 2016

November has been a busy month for DoCoMo’s 5G activities. It had already announced preparations for a 2017 live test with Ericsson and Intel in Tokyo. Following this news, DoCoMo is now reporting groundbreaking results from two separate trials in the 4.5 GHz and the 28 GHz frequency bands. Similarly to what DoDoMo did in previous mobile generations with approaches like MOVA and FOMA, it is conducting joint-development efforts with network manufacturers and terminal suppliers; and, it is marching towards a firm commitment to launch 5G commercially in 2020.

 

In the 28 GHz mmWave, DoCoMo and Samsung Report 2.5Gbps with a Mobile Device Traveling at 150 km/h: DoCoMo, in a joint trial with Samsung, has successfully achieved a data speed of over 2.5Gbps with a mobile device traveling at 150 km/h in a train. This helps verifying the feasibility of stable connectivity for 5G devices in fast-moving vehicles. The test used the 28 GHz mmWave band, one of the candidate bands for use in commercial 5G networks in Japan. To date, no test had achieved a successful wireless data transmission to a fast-moving device due to the large path-loss of high-frequency radio signals. In this trial, the problem was resolved with the use of massive multiple-input multiple-output (MIMO) technologies that incorporate beamforming, which concentrates radio waves in a specific direction, and beam tracking, which adjusts the beam according to the fast-moving mobile device’s location.

 

4.5 GHz Frequency Band, MU-MIMO Trial with Huawei delivers 79.82 bps/Hz/cell: In a separate trial, DOCOMO and Huawei conducted an outdoor trial using the 4.5 GHz frequency band in a 100,000 square-meter field. The trial involved 23 simultaneously connected mobile devices and Docomo set up a 5G base station using the current 3GPP New Radio specification as baseline, and using 200 MHz of spectrum wth  64 transceivers to serve 23 devices, both static and mobile.

DoCoMo and Huawei Trial in 4.5 GHz Band

The trial achieved a cumulative 11.29 Gbps data throughput with latency below 0.5 milliseconds. The trial combined multi-user MIMO (MU-MIMO) technology for simultaneous multiple access and a precoding algorithm that optimizes signals for maximized performance and limits inter-user interference. It achieved a MU-MIMO transmission of a maximum 79.82bps/Hz/cell, which was reportedly 1.8 times better than in the November 2015 outdoor trial conducted in China. “Our success in 5G large-scale field trial in the 4.5 GHz band brought the whole industry one step closer to 5G commercialization by 2020,” said Takehiro Nakamura, VP of DoCoMo’s 5G Lab. “Docomo and Huawei have been expanding their collaboration on 5G from R&D to international spectrum harmonization initiatives for 5G since December 2014.”

DoCoMo Also Testing 5G Apps:   DoCoMo is also conducting 5G application-centric trials, like the one announced with DeNA for remote monitoring of self-driving vehicles. This application will have a proof of concept trial consisting of DoCoMo’s 5G mobile-communications system supporting safety features of self-driving vehicles through remote monitoring and passenger assistance. In the trial, a vehicle and a remote center will be connected via the 5G network that delivers ultra-high-speed data rates beyond 10Gbps with low-latency. During the trial, high-resolution video images captured with high-definition cameras mounted on the vehicle will be transferred real-time over the 5G network to the monitoring center for analysis of possible driving irregularities and for passenger assistance as required.

 

DoCoMo 5G Launch Target is 2020:    Going forward, DoCoMo says it will continue research and development collaboration with world-leading technology vendors in support of its planned launch of a commercial 5G mobile communications system by 2020.
