METHOD FOR TRANSMITTING FEEDBACK INFORMATION THROUGH TERMINAL TO FOR SPLIT BEAMFORMING IN WIRELESS COMMUNICATION SYSTEM AND APPARATUS THEREFOR

摘要

Disclosed is a method for transmitting, by a terminal, feedback information to a network for partial beamforming based on a multi-antenna in a wireless communication system. Specifically, the method comprises: a step of receiving, from the network, reference signals corresponding to antenna sections included in the multi-antenna; a step of selecting one or more beamforming mode among beamforming modes included in a candidate beamforming mode set on the basis of the reference signals, and forming feedback information related to the selected one or more beamforming modes; and a step of transmitting the feedback information to the network, and the feedback information includes a pre-coding matrix index corresponding to at least one of the antenna sections and connection coefficient information for connecting the antenna sections.
