Abstract
Methods, systems, and devices for wireless communications are described. A user equipment (UE) may receive a first configuration of one or more channel state information reference signal resources and a second configuration of a channel state information report associated with the one or more channel state information reference signal resources. In some cases, the second configuration may include at least one of an indication of a codebook, a set of codebook restriction sets, and a configured bandwidth. The UE may then identify a mapping between one or more frequency-domain subbands of the configured bandwidth and each codebook restriction set of the set of codebook restriction sets, and transmit, to the base station, a report indicating one or more precoding matrix indicators from the codebook for each of the one or more frequency-domain subbands based on the mapping.
