Data-aided beam management

Abstract:

Methods, systems, and devices for wireless communications are described. Beam management procedures may increase communications quality and reliability in wireless networks that support narrow directional beams and high frequencies. Some such beam management procedures utilize continuous beam measurements and adaptive beam switching to maintain a threshold link level between devices. A user equipment (UE) may transmit an indication of a capability to perform a first beam refinement procedure in response to a data transmission and using multiple receive beams. The UE may select a communication beam using a first instance of a second beam refinement procedure, and may receive a data transmission from a base station using the selected beam. Based on receiving the data transmission, the UE may perform the first beam refinement procedure and may skip a second instance of the second beam refinement procedure.
