Abstract

Aspects of the present disclosure relate to techniques for codebook subset restriction (CSR). In some cases, a user equipment (UE) receives, from a network entity, codebook subset restriction (CSR) information. The UE determines, based on the CSR information, a restricted beam set for a plurality of antenna panels, determines precoding matrix indicator (PMI) feedback for the antenna panels subject to restricted beam set, and provides the PMI feedback to the network entity.
