1. A method of wireless communication at a first user equipment (UE), comprising:
transmitting, to a second UE, an indication to provide hybrid automatic repeat request (HARQ) feedback for at least one sidelink channel;
transmitting, to the second UE, at least one sidelink transmission via the at least one sidelink channel; and
receiving, from the second UE, an acknowledgement (ACK) or a negative-ACK (HACK) for the at least one sidelink transmission via a physical sidelink feedback channel (PSFCH), wherein the PSFCH includes a long PSFCH format and is associated with a sidelink resource pool that further supports a short PSFCH format, wherein the long PSFCH format includes a length of at least three (3) symbols and the short PSFCH format includes a length of less than three (3) symbols, wherein the long PSFCH format is prioritized over the short PSFCH format when the PSFCH including the long PSFCH format and a PSFCH including the short PSFCH format are scheduled in a same slot in the sidelink resource pool.
