1. A method for wireless communication at a first user equipment (UE), comprising:
receiving sidelink communications from a second UE via a sidelink channel;
transmitting a feedback message to the second UE via a sidelink feedback channel using a first resource configuration, wherein the first resource configuration indicates a first set of one or more sidelink feedback channel resources, the feedback message being based at least in part on the sidelink communications, and wherein the first set of one or more sidelink feedback channel resources is associated with a first set of subchannels of a frequency band and a quantity of cyclic shifting pairs for the sidelink feedback channel; and
performing inter-UE coordination using a second resource configuration, wherein the second resource configuration indicates a second set of one or more sidelink feedback channel resources, the second set of one or more sidelink feedback channel resources different from the first set of one or more sidelink feedback channel resources and associated with a second set of subchannels of the frequency band, and wherein the feedback message is multiplexed with inter-UE coordination signaling using the first set of one or more sidelink feedback channel resources and the second set of one or more sidelink feedback channel resources.
