With the 3GPP Release 15 standard for 5G NR a done deal, Huawei announced it is already moving on to Release 16 standards based on guidance from the IMT-2020 (5G) Promotion Group
Based on the ‘Verification of R16, Future New Functions, and Technologies’ released by the group in February this year, development of standards, R&D, and tests will be simultaneously conducted in China during what Huawei calls the third phase of 5G development.
To that end, Huawei says it has tested and verified a series of new technologies and functions specific to 3GPP R16 across ‘typical’ 5G application scenarios. For example, ultra-reliable and low-latency communications (URLLC) enables three typical scenarios: industry, electric power, and vehicle-to-everything (V2X).
Huawei says its test demonstrates URLLC’s application in new radio (NR) V2X. Huawei provided an end-to-end solution featuring coordinated design of C-V2X (NR URLLC), a roadside unit (RSU), and mobile edge computing (MEC).
In the test, a car making an emergency lane change in front of a self-driving car was monitored via a camera on the RSU – the video signal was transmitted to the MEC in real time. The MEC coordinated with the V2X control center to make a decision, send commands via the NR Uu air interface to the self-driving vehicle to implement a lane change or brake, etc. At the same time, in order to maintain the formation, the rear vehicle exchanges information with the preceding vehicle via the NR sidelink.
Other Release 16 tests conducted by Huawei involved massive machine type communication (mMTC), Type II codebook optimization, multiple codes, and feedback enhancement.
Huawei said the completion of Release 15 – announced last week – serves as a good starting point for research on Release 16 study items and work items. The full set of 5G standards meeting all requirements of the ITU is expected to be completed by December 2019.
