1. A method of wireless communication performed by a user equipment, comprising:
comparing a bandwidth of a sounding reference signal (SRS) resource and a bandwidth of a physical uplink shared channel (PUSCH) resource to determine whether the bandwidth of the SRS resource is smaller than, greater than, or equal to the bandwidth of the PUSCH resource;
precoding, using a first precoder, a first portion of a PUSCH communication that is to be transmitted in a portion of the PUSCH resource that overlaps with the bandwidth of the SRS resource;
precoding, using a second precoder, a second portion of the PUSCH communication that is to be transmitted in a portion of the PUSCH resource that does not overlap with the bandwidth of the SRS resource; and
transmitting a precoded PUSCH communication that comprises the first portion and the second portion.
