Abstract
A communication method of a base station transmits a modulation signal based on an OFDM (orthogonal frequency division multiplexing) modulation scheme to a plurality of communication terminals. The method includes forming a transmission frame on which a first subcarrier group and a second subcarrier group are arranged, and determining on a per frame basis, which subcarrier group of the first subcarrier group and the second subcarrier group is allocated to each of the plurality of communication terminals and what number of subcarriers are selected from the subcarrier group that is allocated to each of the plurality of communication terminals. The method further includes forming the transmission frame based on the determined subcarrier group and the determined number of subcarriers, transmitting the modulation signal including the transmission frame, and receiving feedback information including radio propagation condition estimation information from each of the plurality of communication terminals.
