Claim of US Patent No. 10,368,325

1. A method for beam adaptation in a beam-based communications system including user equipment (UE) and a transmit-receive point (TRP), the method comprising:determining, by the UE, 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, wherein the BHR is a difference between the UE maximum beamforming gain and the beamforming gain of the UE beam between the UE and the TRP;
in response to the determining sending, by the UE, the BHR to the TRP; and
receiving, by the UE, a beam adaptation indication from the TRP wherein the beam adaptation indication is in accordance with the BHR sent to the TRP.
