Patent ID: 8588342

Claim:
A mobile terminal, comprising: a transmitter operable to perform radio transmission of first data by using a first sub carrier group according to an orthogonal frequency divisional multiplexing (OFDM) method and operable to perform radio transmission of second data by using a second sub carrier group according to the OFDM method; a receiver operable to receive signals from a plurality of antennas included in at least one base station; a determiner operable to determine sub carrier group used by each of the plurality of antennas in a downlink communication based on the signals received by the receiver, wherein the transmitter transmits information including the determined sub carrier group to the at least one base station; a radio environment measurement unit operable to measure radio environments of a plurality of sub carriers between a first antenna included in a base station and the mobile terminal and radio environments of a plurality of sub carriers between a second antenna included in a base station and the mobile terminal; and a sub carrier setting unit operable to set the first sub carrier group and the second sub carrier group based on results of the measurement, wherein the base station having the first antenna performs reception processing for data transmitted by the first sub carrier group and the base station having the second antenna performs reception processing for data transmitted by the second sub carrier group, and wherein the determiner determines the sub carrier group corresponding to each of the first and second antennas so that a proportion of sub carriers at which fading has occurred to sub carriers assigned to the first and second antennas becomes equal between the first and second antennas.
