Title:
STAND-ALONE SIDELINK COMMUNICATION OVER UNLICENSED BAND
Document Type and Number:
WIPO Patent Application WO/2021/207961
Kind Code:
A1
Abstract:
Wireless communications systems and methods related to stand-alone sidelink communication are provided. A first user equipment (UE) determines system parameter information to initiate a sidelink communication. The first UE transmits, in one or more first subbands of a plurality of subbands within a shared radio frequency during a first time period, the system parameter information. The first UE communicates, with a second UE in a second subband of the plurality of subbands during a second time period different from the first time period, sidelink data based on the system parameter information.
