Abstract

A method of transmitting data in a wireless communication system is provided. A user equipment receives an antenna group selection indicator indicating an antenna group comprising two or more activated transmit antennas among a plurality of transmit antennas, selects a transmit antenna to be activated according to the antenna group selection indicator, and transmits the data by supplying power to a power amplifier corresponding to the selected transmit antenna, wherein the number of power amplifiers is less than the number of transmit antennas and a type of the antenna group is determined according to the number of the power amplifiers. Accordingly, information on an antenna group in use among a plurality of antennas can be effectively transmitted.
