OUT-BAND PHYSICAL SIDELINK FEEDBACK CHANNEL (PSFCH) RESOURCES FOR SIDELINK UNLICENSED SPECTRUM: abstract simplified (17697354)
The abstract describes a method for wireless communication using a transmitter user equipment (UE). The method involves receiving a configuration of a resource pool and transmitting a physical sidelink shared channel (PSSCH) on a resource in the resource pool. The transmitter UE also sends a request for a hybrid automatic repeat request (HARQ) response for the PSSCH. The HARQ response is received from the receiver UE over a physical sidelink feedback channel (PSFCH) resource.
