Abstract:
1. A radio communication method in which each of a plurality of base stations uses at least one of a plurality of frequency blocks to perform radio communication with at least one mobile station, wherein the plurality of base stations include, for each mobile station, a serving base station and one or more non-serving base stations, the method comprising: a step in which each of the plurality of base stations transmits pilot signals using each of the plurality of frequency blocks; a step in which the at least one mobile station measures a signal-to-interference ratio (SIR) of each of the pilot signals which are received from the serving base station; a first selection step in which the mobile station selects frequency blocks on the basis of the measured SIRs; a step in which the mobile station measures a reception power of each of the pilot signals which are received from non-serving base stations; a second selection step in which the mobile station selects frequency blocks from the frequency blocks selected in the first selection step, on the basis of the measured reception powers; and a step in which the mobile station transmits channel quality information, of each of the frequency blocks which are selected in the second selection step, to the base station.
