PSFCH TRANSMISSIONS ON AN UNLICENSED SPECTRUM

WIPO Patent Application WO/2024/093399

A1

Embodiments of the present disclosure relate to physical sidelink feedback channel (PSFCH) transmissions on an unlicensed spectrum. In some embodiments, a user equipment (UE) determines a transmission resource for a groupcast transmission, based on a number of candidate PSFCH resources associated with the groupcast transmission and a number of group members communicating with the UE. Then, the UE performs the groupcast transmission based on the transmission resource. Moreover, the UE receives, from the group members, positive-negative acknowledgement for the groupcast transmission. In this way, it is possible to improve the capacity of the PSFCH resources, and thus improve sidelink transmission efficiency.
