Reporting beam measurements for proposed beams and other beams for beam selection
Various aspects of the present disclosure relate to beam management procedures in wireless communications systems. Some implementations of the present disclosure more specifically provide techniques for reporting measurements for proposed beams (such as beams predicted to be the best beams for communications to and from a UE and a network entity) and other beams detected by the UE. The techniques may be used, for example, to identify mismatches between a proposed set of beams and actual best beams for communications to and from a UE and a network entity and allow for the retraining of machine learning models used to identify the proposed set of beams for communications to and from a UE and a network entity.
