APPARATUS AND METHOD FOR DETERMINING BEAM IN WIRELESS COMMUNICATION SYSTEM

Abstract

A method to operate a receiving node is provided. The method includes receiving a first set of reference signals being transmit-beamformed using transmit beam groups in at least one transmitting node with receive-beamforming using receive beam groups. The method also includes transmitting information to select one transmit beam group of the transmit beam groups to one of the at least one transmitting node. The method further includes receiving a second set of the reference signals being transmit-beamformed using transmit beams of the one of the transmit beam groups in the at least one transmitting node with receive-beamforming using receive beams of one of the receive beam groups.
