Abstract:
1. A method of transmitting control information in a wireless communication system, the method comprising: configuring, by a base station, downlink control information (DCI) comprising a plurality of information fields, wherein the plurality of information fields comprise a transmitted precoding matrix indicator (TPMI) information field for indicating a codebook index, a downlink power offset of power for downlink data transmission, and a virtual resource block (VRB) assignment flag field for identifying whether a resource block is assigned in a consecutive manner or a distributed manner, wherein the downlink power offset of power for downlink data transmission is 1bit information, which is set to a first offset value indicating ‘0 (dB)’ or a second offset value indicating ‘−10log wherein the downlink power offset replaces a precoding matrix indicator (PMI) confirmation field for indicating whether precoding is performed on downlink data by using a PMI reported by a user equipment; and transmitting, by the base station, the downlink control information.
