Title:
SYSTEM AND METHOD FOR BEAM ADAPTATION IN A BEAM-BASED COMMUNICATIONS SYSTEM
Document Type and Number:
WIPO Patent Application WO/2018/141205
Kind Code:
A1
Abstract:
A method for beam adaptation in a beam-based communications system is provided. The beam-based communications system includes user equipment (UE) and a transmit-receive point (TRP). The method includes that UE determines a beamforming gain headroom (BHR) based on a UE maximum beamforming gain and a beamforming gain of a UE beam between the UE and the TRP, sends the BHR to the TRP, and receives a beam adaptation indication from the TRP.
