Methods, systems, and devices for wireless communications are described. A first device may monitor for a set of reference signals from a second device using a set of directional beams. The first device may perform measurements on the received reference signals and select a subset of directional beams from the set of directional beams based on the performed measurements. Each directional beam may be associated with a set of beamforming weights. The first device may communicate with the second device using a dynamic set of beamforming weights. The first device may form the dynamic set of beamforming weights using a combination of beamforming weights from each set of beamforming weights associated with the subset of directional beams. The dynamic set of beamforming weights may be different from each set of beamforming weights associated with the subset of directional beams.

Methods for dynamic beamforming weight construction based on directional measurements

Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may identify a channel matrix of the UE. The UE may identify a set of beam weights according to the channel matrix. The UE may identify a set of beam properties based at least in part on an index, wherein the index is based at least in part on the set of beam weights, and wherein the index is identified without storing the set of beam weights in a long-term memory of the UE. The UE may generate a beam using the set of beam properties. Numerous other aspects are described.
