Today Linlang Resource Network found that 9 January 29day 5G promotion group represents , 2022 year 923 China Information and Communications Research Institute MTNet Research Institute, IMT-2020 Propulsion Group completed the world's first 5G R17 RedCap base station and chip key technology test.
test uses Huawei commercial base station and commercial chips for well-known domestic manufacturers. According to the specification requirements of the "5G enhancement technology R&D test NR RedCap Key Technical Requirements" compiled by the IMT-2020 (5G) Promotion Group, found that , R17 RedCap has been transferred from standard to commercial, and the industrial chain has initially met the commercial conditions.
China 5G for commercial use For three years, China has been at the forefront of the world in the integration of 5G base station more than two million , 5G and vertical industries. 5G should 40 major category, 5G25G Virtual Professional Network 6500, 9 January Ministry of Industry and Information Technology Ningbo "5G Industrial Internet " " " on-site business meeting released "5G" Full Connection Factory Construction Guidelines, which proposes documents for the next few years.
As the integrated application of 5G and industry to develop in depth and scale, the problem of expensive terminal modules of 5G has become increasingly prominent. The price of 5G industry module has dropped from 201950020195002 Korean won to 20224502 Korean won, but compared with the price of 4G 100 Korean won, the cost pressure on the industry scale is still very large.
In January this year, the 3GPP R17 standard protocol was frozen, and RedCap is a key technology for medium and high-speed interconnection solutions. RedCap reduces the terminal spectrum bandwidth to 20MHz, and uses R or 2R Receive antenna. In the future, the price of 5G module can be greatly reduced to less than 00 yuan, and can also inherit the advantages of 5G network slice and low latency. Compared with 4G interconnect technology, RedCap has advantages such as intergenerational advantages, performance improvement, functional enhancement and industry RedCap acceleration.
In addition, according to Linlang Resource Network, , this time, the core technology test of RedCap UERedCap UE basic residency and access, conversion, RedCap UE and general 5G UE shares initial BWP, RedCapUEIndependent uplink /downlink initial BWP, uplink speed and other test contents. This test will promote the maturity of the 5G RedCap network and chip industry chain, laying a solid foundation for the scale commercialization of 5G IoT.
