1. A method of wireless communication, comprising:
receiving a configuration of multiple resource pools for sidelink communications, each resource pool defined by a different set of time domain resources;
receiving at least two repetitions of a sidelink control information (SCI) on at least two of the multiple resource pools, each repetition of the SCI includes a same reservation for a physical sidelink shared channel (PSSCH) on a respective resource pool;
performing soft combining on the at least two repetitions of the SCI to determine resources for the PSSCH, wherein a first resource pool of the multiple resource pools overlaps with a second resource pool of the multiple resource pools on at least some overlapping resources wherein the reservation in the SCI on the overlapping resources indicates a PSSCH on the first resource pool and a PSSCH on the second resource pool or indicates whether a PSSCH is scheduled on the first resource pool or the second resource pool; and
decoding the PSSCH based on the SCI.
