Huawei and Telefonica deepen 5G cooperation with CloudRAN and core focus

Huawei and Telefonica, already partners in 5G R&D, have signed a joint agreement to cooperate on the development of next generation Radio Access Network (RAN) and core network technology. A statement from the companies said that 5G Core architecture evolution and research on CloudRAN would be the major cooperation areas. Specifically the companies will look at CloudRAN, User-centric “no cell” tech, re-architecting the core and Massive MIMO innovation. “No cell” technology is the term Huawei gives to the virtual RAN – whereby…

5Qs on 5G: MycomOSI

The latest in our 5Qs on 5G series sees Sandeep Raina, Product Marketing Director explain how MYCOM OSI, a company that provides assurance and analytics within mobile networks, will fit into the 5G ecosystem.  Can you define where in 5G networks MYCOM OSI’s technology will play? As Communications Service Providers (CSPs) make the transition to digital service providers, with the help of big data analytics, cloud technologies, heterogeneous HSPA/LTE/WiFi/5G access and ultra-fast, agile service delivery capabilities, they must recognise that their operational environment…

Ericsson slices up network slicing Proof of Concept

NTT DoCoMo said it had demonstrated a Network Slicing Proof of Concept, using commercial technology from Ericsson. The trial saw the operator design network slice and selection functions, with Ericsson’s performing the control and management of the slicing in the network. There wasn’t any further detail as to which elements were used, the architecture deployed, or indeed what slices were defined and created. Perhaps there will be more detail on offer at 5G World in London,where the companies say they will…

ZTE joins Huawei with “all good” results from China’s IMT-2020 tests

ZTE has said that tests of high frequency radio access and “massive MIMO”, carried out for China’s IMT-2020 (5G) Promotion Group, have all gone as expected. The vendor, which is one of those testing technologies in Phase I of the Promotion Group’s, followed Huawei in releasing a few details of successful tests of radio interface technology. ZTE said it had tested “high frequency” radio access in indoor conditions with both LOS and NLOS conditions, and had seen uplink and downlink…

Proactive caching in 5G networks

“Living on the Edge: The Role of Proactive Caching in 5G Wireless Networks” is a paper by Ejder Bastug, Mehdi Bennis and Merouane Debbah that recently won an award for best tutorial article from the IEEE Communications Society, 2016. The paper outlines a couple of potential use cases for edge computing, with a focus on the potential benefits that the deployment of proactive caching at the network edge could bring. One of the co-authors, Mehdi Bennis, has written a brief outline of the themes…

5G spec process starts for real at 3GPP meeting in Busan

Today is the last day of a five day meeting being held in Busan, South Korea. The meeting, of the 3GPP’s RAN Working Group one and officially numbered 3GPPRAN1#84, has seen around 400 delegates gather together to develop specifications of next generation radio network and air interface technologies. Host of the meeting, Samsung Networks, described the meeting as the first at which work to determine specifications of 5G radio and air interface standards happened in earnest. A release from Samsung said, “This meeting…

SK Telecom says 28GHz trials go well

SK Telecom said today that tests of equipment operating at the 28GHz mmWave band, carried out since August 2015, had gone well. The company has been testing base stations in the frequency, along with a test mobile device within a vehicle since August 2015, based on test equipment from Samsung. One of the features under test was 3D beam forming – steering antenna beams both horizontally and vertically. Although the companies released no firm details as to speed, performance, propagation…

Researchers achieve “world record” spectral efficiency with massive MIMO

Researchers at Bristol University and Lund University have demonstrated 128 antenna MIMO that has achieved very high spectral efficiencies, and could be significant for 5G radio interface design. A press release from Bristol University claimed that it had achieved a spectral efficiency – expressed as bits per second per Hertz – of 1.59Gbit/s in a 20MHz channel. That represents a 12x improvement on current LTE cellular efficiencies, and is a “world record” according to the PR headline. The research team were conducting…

Components of a 5G architecture

The devil is in the detail, they say, and when it comes to 5G there is a lot of detail still to be thrashed out. Quite how much detail is evident in the latest whitepaper – 5G RAN Architecture and Functional Design – delivered by 5G-PPP’s METIS-II. The paper raises a lot of questions, but can come to very few definitive answers as yet, although it does propose a number of likely answers to each question. These include new AI design,…

National pride in “leading 5G” is a barrier to 5G development

This week the UK’s treasury chief repeated his Government’s desire to make the UK a world leader in 5G. Similarly, EC Digital Commissioner Guther Oettinger was off again on his desire to position Europe as a 5G leader. Despite the increasing tendency of governments to talk of a country, or even region, “leading in 5G” it is empty talk. There are only two potential ways to “lead in 5G”, one is in leading the technology development that goes towards 5G.…
