Abstract:
Apparatuses and methods for obtaining and providing hybrid automatic repeat request acknowledgement (HARQ-ACK) information. A method for providing HARQ-ACK information includes receiving a configuration for a slot offset value and receiving a physical sidelink shared channel (PSSCH) over a number of sub-channels in a first slot. The PSSCH includes a transport block (TB). The method includes determining a second slot as an earliest slot with resources for transmission of a physical sidelink feedback channel (PSFCH) that is after the first slot by a number of slots equal to the slot offset value. The PSFCH includes the HARQ-ACK information that is in response to reception of the TB. The method further includes transmitting the PSFCH in the second slot.
