Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may receive, from a base station, a channel state information reference signal that includes a plurality of resource blocks. The UE may sub-sample one or more portions of the plurality of resource blocks prior to performing one or more channel state feedback computations. Accordingly, the UE may perform the one or more channel state feedback computations based at least in part on the one or more sub-sampled portions of the plurality of resource blocks and transmit, to the base station, a channel state feedback report based at least in part on the one or more channel state feedback computations that are performed using the one or more sub-sampled portions of the plurality of resource blocks. Numerous other aspects are provided.
