Abstract
Apparatuses and methods for transmission window determination for a physical sidelink feedback channel (PSFCH) in a wireless communication system. A method of user equipment (UE) includes receiving a set of configurations from a higher layer and receiving a physical sidelink shared channel (PSSCH). The PSSCH enables hybrid automatic repeat request (HARQ) feedback. The method further includes determining a transmission window for a PSFCH; performing a sidelink (SL) channel access procedure before a transmission occasion in the one or multiple transmission occasions; and transmitting the HARQ feedback in the transmission occasion for the PSFCH over a channel upon successfully performing the SL channel access procedure. The transmission window includes the one or multiple transmission occasions for the PSFCH and the one or multiple transmission occasions are based on at least one of: a window offset, an interval between two neighboring transmission occasions, and a number of transmission occasions.
