Title:
COMMUNICATION METHOD AND APPARATUS
Document Type and Number:
WIPO Patent Application WO/2024/032285
Kind Code:
A1
Abstract:
A communication method and apparatus. The method comprises: a first terminal device determines a first channel access priority class (CAPC) and then transmits, to a second terminal device, first information for indicating a second CAPC, wherein the second CAPC is the same as the first CAPC, or the second CAPC is determined on the basis of the first CAPC; and the second CAPC is used by the second terminal device to perform listen before talk (LBT) on a first physical sidelink feedback channel (PSFCH). According to the method, the second terminal device can perform LBT on a PSFCH on the basis of a CAPC indicated by the first terminal device, so that the CAPC transmitted by the PSFCH can be flexibly adapted to actual service communication requirements, and the communication quality of a sidelink unlicensed spectrum (SL-U) is improved.
