Considering that Huawei is the chairman of the 5G standard committee of 3GPP and owns the largest number of standard essential patents (SEP) in the world, the United States has to allow domestic enterprises to cooperate with Huawei on the 5G standard, otherwise American enterprises will be gradually marginalized in the field of international mobile communication. The United States hopes that through cooperation with Huawei in standards, it can enhance the voice of American companies in 5G standards.
In R 16 protocol, 5G application scenarios will not involve low-power wide-area coverage (LPWA) IoT scenarios, and NB-IoT and Cat 1 will be the main application technologies of low-power IoT.
The main research contents of R 16 include: car networking, industrial Internet of Things, and unlicensed frequency band network access. R 16 focuses on LTE-V2X, trying to solve some advanced application scenarios, including queue driving, V2I function enhancement, sensor expansion, advanced driving and remote driving.
R 16 will further study the enhancement of URLLC to meet the application challenges of industrial Internet of Things (IIoT). R 16 focuses more on improving reliability, reducing delay and optimizing timing. Most of these goals will be achieved by improving the protocol and physical layer.
R 16 also includes using unlicensed spectrum, using LAA: licensed auxiliary access (LAA) unlicensed spectrum, or using unlicensed spectrum in independent operation without the assistance of authorized operators.
After the R 16 standard was finalized, the formulation of the 5G standard entered the second stage (5G second stage). V2X applications related to the electric vehicle industry will be the next killer application of 5G.
