摘要
Certain aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may determine at least one phase estimate for at least one beam received by the user equipment during a beam training or channel estimation procedure; and/or provide the at least one phase estimate to a base station from which the at least one beam is received for the base station to reconstruct an estimated channel matrix of the user equipment. In some aspects, a base station may receive feedback information from a UE identifying phase estimates for a plurality of beams transmitted to the UE, wherein the feedback information relates to a selected beam for the UE and one or more other beams of the plurality of beams; and/or determine an estimated channel matrix for the UE based at least in part on the feedback information. Numerous other aspects are provided.
