METHOD AND APPARATUS FOR TRACKING BEAM IN WIRELESS COMMUNICATION SYSTEM
摘要
A method and an apparatus for tracking a beam in a wireless communication system are provided. In the method, a plurality of downlink reference signals are received from a base station and at least one downlink transmission beam pattern is determined. A plurality of uplink reference signals are transmitted to the base station, each includes identifier information corresponding to the determined at least one downlink transmission beam pattern. ACKnowledgement (ACK) information indicating that the base station has successfully received an identifier included in the identifier information corresponding to the determined at least one downlink transmission beam pattern from identifier information corresponding to an uplink transmission beam pattern and that the plurality of uplink reference signals from the base station is received.
