1. A method comprising:
receiving, by a wireless user device, sidelink data via a physical sidelink shared channel (PSSCH), wherein at least a portion of the PSSCH is in a subchannel of a first slot, and wherein the subchannel of the first slot comprises a plurality of physical resource blocks (PRBs);
determining, based on a subchannel index of the subchannel of the first slot, a resource for physical sidelink feedback channel (PSFCH) transmission, wherein the resource for PSFCH transmission is in a subchannel of a second slot;
determining, based on a value determined based on a sidelink source identity (ID) and a group member ID, an index of the resource for PSFCH transmission;
transmitting, via the resource for PSFCH transmission, feedback information associated with the received sidelink data; and
determining, based on a slot number of the first slot, a PRB offset for determining a frequency location, of the resource for PSFCH transmission, in the subchannel of the second slot,
wherein a number of slots in a hybrid automatic repeat request (HARQ) associated slot set, NslotHARQ, is N, and
wherein a PSFCH resource exists per every N slots.
