METHOD AND APPARATUS FOR TRANSMITTING CONTROL INFORMATION IN WIRELESS COMMUNICATION SYSTEM

摘要

A method for, at an eNB, transmitting control information to a UE in a wireless communication system includes precoding a codeword including downlink control information using one of precoding matrices included in a candidate precoding matrix set of a codebook, wherein the precoding matrices included in the candidate precoding matrix set are used by the UE for attempting to de-precode for the downlink control information.
