Abstract:
Methods, systems, and devices for wireless communications are described. A user equipment (UE) may communicate with other network devices as part of a wireless communications system. The UE may identify a blockage corresponding to one or more antenna arrays of a set of antenna arrays based on using a first set of beam weights, which may correspond to a static beamforming codebook of the one or more antenna arrays. The UE may switch from a static beamforming codebook-based beam weight determination to a dynamic beamforming codebook-based beam weight determination. The UE may then determine a second set of beam weights to use for the one or more antenna arrays based on the dynamic beamforming codebook-based beam weight determination. The UE may then communicate using the one or more antenna arrays according to the second set of beam weights.
