Beam Estimation Aided Beam Acquisition

Abstract:

Herein is disclosed a beam estimation system comprising one or more transceivers, configured to transmit a plurality of first-stage reference beams, and to receive a first quality identifier corresponding to a first first-stage reference beam with a strongest signal strength and a second quality identifier corresponding to a second first-stage reference beam with a second strongest signal strength; and one or more processors, configured to determine a second-stage reference beam region based on the first quality identifier and the second quality identifier.
