TECHNIQUES FOR BEAMFORMING ENHANCEMENT AND FEEDBACK

Abstract:

Methods, systems, and devices for wireless communications are described. A user equipment (UE) may be configured to measure and report a beam combination parameter to a base station to improve generation of a dynamic beam for beamformed communications. In some examples, the UE may measure the beam combination parameter in terms of angular spread/coverage area of individual beams, array or signal gains at antennas or panels of the UE, additional panel/antenna module related information, etc. Based on the reported beam combination, the base station may generate the dynamic beam and indicate a beam configuration to the UE for subsequent communications. In some examples, distinct beam combination parameters may be reported for each component carrier or subband in a carrier aggregation (CA) configuration (e.g., inter-band CA or intra-band CA).
