Huawei announced that it has achieved initial results in the verification and evaluation of the R16 standard under the organization of the IMT-2020 (5G) promotion group. This test is an important part of the third phase of China's 5G technology R&D trials, and is based on the "New Features and New Technology Verification for R16 and Future" issued by the IMT-2020 5G Promotion Group in February this year. "Standards, R&D and testing" work in parallel. Huawei conducted test and verification for new 5G R16-based application scenarios and new features introduced by 3GPP R16, and continued to support the advancement of 3GPP international standards.
Huawei has enabled uRLLC (Ultra-Reliable and Low Latency Communications) three typical application scenarios with 5G NR: industrial, power, and V2X (Vehicle to Everything). The NR V2X R16 pre-targeting candidate technology is verified, and the uplink and downlink receiving performance is improved by the terminal super diversity technology. By means of the joint design of NR uRLLC and RSU and MEC, an ultra-low latency and ultra-high reliability end-to-end solution is provided. In this test, the front vehicle emergency lane change was deployed on the roadside RSU camera and the video signal was transmitted to the MEC in real time. The MEC cooperates with the V2X controller center to make decisions, through the NR Uu air interface to send follow-up instructions to the self-driving vehicle following the car, implementing lane change or brake operations, while maintaining the formation, the rear vehicle passes the NR SL (Sidelink) and the former Car interactive information, keep formation.
For mMTC (massive Machine Type Communication?, Massive Internet of Things communication), mMTC is a candidate technology at R16 or later, especially for uplink video transmission. In this test, Huawei used the uplink NR air interface to run video services on the 5G network and completed the 5G enabled AI (Artificial Intelligence) campus application demo, demonstrating that 5G enabled powerful campus security functions.
The eMBB (enhanced Mobile Broadband) scenario is widely used in the R15, and the R16 still needs to explore its unknown applications. The R16 candidate key technologies for 3GPP, such as Type II codebook optimization, multi-codeword, feedback enhancement, etc., are also continuously advancing.
Currently, 5G is at the critical stage of standardization. In June 2018, it was the determination of the Stand Alone (SA) standard. The release of the world's first version of the 5G standard, R15, was also the key time node for the R16 standard SI/WI start-up. In December 2019, the complete 5G standard that satisfies all requirements of the ITU (International Telecommunication Union) will be completed. Huawei continues to fully prepare for R16 standardization, supports the standardization of 5G enhancement technologies, and continues to explore areas of system performance enhancement. Through the development of more 5G typical application integration experiments, it will promote the development of 5G services and applications.
