Abstract
A link adaptation method of a wireless communication apparatus including a plurality of antennas to receive data signals through a channel from a base station includes estimating a plurality of data transmission rates of the data signals and power consumptions to process the data signals under a plurality of reception conditions of the wireless communication apparatus based on combinations in a first quantity of transmission ranks from the base station and a second quantity of antennas among the plurality of antennas; calculating a plurality of energy efficiencies by using the power consumptions and the plurality of data transmission rates; and generating a channel state information to perform a link adaptation based on the plurality of energy efficiencies, and determining a number of antennas to receive the data signals, among the plurality of antennas.
