A recently granted patent (Publication Number: US11937276B1) discloses a method for sidelink communication involving a terminal device receiving a first physical sidelink shared channel (PSSCH) and performing channel access on a shared spectrum. The method includes transmitting a first physical sidelink feedback channel (PSFCH) carrying feedback information associated with the PSSCH. The patent further details the determination of indication information based on various factors like resource blocks, PSFCH transmission resources, and service type corresponding to the PSSCH.

Additionally, the patent describes a terminal device equipped with processors and computer-readable storage media to execute operations related to receiving PSSCH, performing channel access, and transmitting PSFCH. The terminal device is designed to determine the availability of idle PSFCH transmission resources and adjust transmission based on feedback information received. The patent also covers the interleaving of PSFCH transmission resources and the use of short control signaling based on channel listening results. Overall, the patent aims to optimize sidelink communication by efficiently utilizing resources and adapting transmission strategies based on feedback received during the process.
