Method and device used in wireless communication node

Technical field

This application relates to a transmission method and device in a wireless communication system, and more particularly to a transmission method and device related to a side link (Sidelink) in wireless communication.

Background technique

In the future, the application scenarios of wireless communication systems are becoming more and more diversified, and different application scenarios put forward different performance requirements for the system. In order to meet the different performance requirements of multiple application scenarios, it was decided at the plenary meeting of 3GPP (3rd Generation Partner Project) RAN (Radio Access Network, radio access network) #72 that the new radio interface technology (NR, New Radio (or Fifth Generation, 5G) conducted research, passed WI (Work Item) of NR at the 75th plenary meeting of 3GPP RAN#, and started standardization of NR.

In response to the rapidly developing Vehicle-to-Everything (V2X) business, 3GPP has initiated standard formulation and research work under the NR framework. At present, 3GPP has completed the formulation of requirements for 5G V2X services and has written it into the standard TS22.886. 3GPP has defined 4 Use Case Groups for 5G V2X services, including: Automated Queued Driving (Vehicles Platnooning), support Extended sensors (Extended Sensors), semi/automatic driving (Advanced Driving) and remote driving (Remote Driving).
