Spanish telecoms giant Telefonica and Chinese technology vendor Huawei claim to have achieved a new milestone with what they claim is ‘the world’s first proof-of-concept (PoC) 5G user centric and no cell (UCNC) RAN architecture’, which has been tested at their 5G Joint Innovation Lab.
With 5G UCNC one of the innovation projects that comes under the ‘5G&NG-RAN Joint Innovation Agreement’ signed by the two companies in June 2016, a press release noted that in the PoC tests 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. Telefonica and Huawei will now reportedly continue with the next phase PoC test, in which they aim to enhance the cell edge spectral efficiency, in order to avoid end-user experience degradation at the cell edges and any service interruption across the network.
Meanwhile, in addition to the UCNC PoC tests, Huawei and Telefonica also confirmed the successful demonstration of mmWave Multi-User MIMO technology based on 5G New Radio (NR) and Massive MIMO TDD technology. In this demonstration 70Gbps cell throughput was said to have been reached by mmWave Multi-User MIMO by delivering more than 35Gbps data rates to each user.
Commenting on the technology developments, Telefonica Global’s chief technology officer Enrique Blanco said: ‘Telefonica’s collaboration with Huawei on 5G has allowed us to reach disruptive results like the use of User Centric No Cell eliminating handover between cells and reducing interference, which is a significant step towards making 5G a really differential mobile system. With this PoC, included in the trial activities of Telefonica in 5G, we can highlight the progress towards developing new technological elements of 5G that provide an important opportunity to position 5G as a transformative element for all services and applications that depend on excellent connectivity.’
