Abstract
Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may receive, from a network node, one or more downlink reference signals during a beam training procedure. The UE may estimate, based at least in part on one or more metrics associated with the one or more downlink reference signals received during the beam training procedure, a covariance matrix associated with multiple candidate beam quads used to transmit or receive the one or more downlink reference signals. The UE may select, from among the multiple candidate beam quads, a beam quad that corresponds to a group of four beams to optimize one or more parameters associated with the covariance matrix. The UE may communicate with the network node using the selected beam quad. Numerous other aspects are described.
