METHOD AND DEVICE FOR TRANSMITTING FEEDBACK SIGNAL

摘要

Provided are a method and a device for generating and transmitting feedback information on a plurality of signals generated by different precoding schemes in a wireless communication system. The method for transmitting a feedback signal comprises: receiving information which determines one of two pre-coding schemes as a first pre-coding scheme and the other as a second pre-coding scheme; determining a first pre-coding matrix index (PMI) for the first pre-coding scheme; determining a first transmission power for the first pre-coding scheme; determining a second transmission power for the second pre-coding scheme on the basis of the first transmission power and a preset target power value; determining a second pre-coding matrix index (PMI) for the second pre-coding scheme; and transmitting feedback information comprising the first PMI and the second PMI to a transmission terminal.
