1. A method of wireless communication performed by a user equipment (UE), the method comprising:
receiving, using a first set of frequency resources comprising at least a first interlace of resource blocks (RBs) in a plurality of RB-sets of a shared frequency band, a sidelink (SL) data communication; and
transmitting, using a second set of frequency resources comprising at least a second interlace of RBs in two or more RB-sets of the plurality of RB-sets of the shared frequency band, a SL feedback communication for the SL data communication,
wherein the transmitting the SL feedback communication is based on a mapping of the plurality of RB-sets to the two or more RB-sets, wherein the first set of frequency resources is different from the second set of frequency resources,
wherein the mapping of the plurality of RB-sets to the two or more RB-sets comprises a mapping of a first slot to the first set of cyclic shift (CS) pairs and a mapping of a second slot to the second set of CS pairs, and
wherein the mapping of the first slot to the first set of CS pairs and the mapping of the second slot to the second set of CS pairs are based on a hashing function.
