Apparatus and method for adaptive transmission power normalization in wireless communication system

The present invention is based on that of the transmission power normalization (normalization) in a wireless communication system performing a hybrid (bybrid) beamforming, the operation method of the transmitting end, the process and the control information for transmitting control information related to transmission power normalization the transmission process and the pre-coding matrix and a signal normalization using the process and the normalization factor that determines the normalization factor corresponding to the combination of the analog beam for receiving information indicative of a pre-coding matrix and an analog beam selected it involves.
