ASYMMETRIC CAPABILITY-DRIVEN METHODS FOR BEAM TRACKING IN MM-WAVE ACCESS SYSTEMS

摘要

A method, apparatus, and computer program product for operating a user equipment (UE) are provided. The apparatus establishes a wireless communication link with a millimeter wave base station (mmW-BS) based on a transmission beam from mmW-BS, the transmission beam having a transmission beam direction, and at least digital, analog, or at least associated with the mmW-BS. Receiving beamforming performance information indicating one of the hybrid beamforming performance, and based on the beamforming performance information and the transmission beam associated with the wireless communication link, N number of received beam directions from mmW-BS for each of the M reception beam directions of the UE. Scan the transmission beams.
