1. A method of wireless communication performed by a first user equipment (UE), comprising:
receiving a communication from a second UE; and
transmitting, to the second UE, sidelink hybrid automatic repeat request acknowledgement (HARQ-ACK) feedback using a sidelink component carrier based at least in part on the communication received from the second UE, wherein the sidelink component carrier is associated with conveying the sidelink HARQ-ACK feedback when sidelink carrier aggregation is configured for a group of UEs that includes the first UE and the second UE, wherein the sidelink component carrier is selected based at least in part on a rate matching pattern applied (i) for each sidelink component carrier or for each sidelink resource pool across a plurality of sidelink component carriers, or (ii) per band across a plurality of intra-band sidelink component carriers.
