    摘要： A mobile communication method according to the present invention includes the steps of: determining, at a mobile station, a first cell with the largest interference amount among a plurality of cells in accordance with reception quality of a reference signal in the plurality of cells, when radio links are established between the mobile station and the plurality of cells; transmitting, from the mobile station to the plurality of cells, identification information of the first cell; and scheduling, at a radio base station which manages each of the plurality of cells, to transmit a data signal addressed to the mobile station via a resource that is unusable by the first cell.

    摘要： A radio base station communicates with mobile terminals and is configured to be able to execute radio transmission to the mobile terminals using resources that are the same as resources used by a second radio base station forming a second cell having a smaller area within a first cell formed by the radio base station itself and is configured to collaborate with the second radio base station for inter-cell interference control. The radio base station sets a modulation system having a modulation level that is less than that of the modulation system provisionally determined as the modulation system for mobile terminals to which a resource group having a low transmission power is assigned and adjusts transmission parameters in a case in which the modulation system provisionally determined for the mobile terminals to which the resource group having the low transmission power is assigned, is inappropriate for the low transmission power.

    摘要： A radio communication system includes a first radio base station, second radio base stations, and mobile stations. Each of the mobile stations measures a first reception characteristic value and a second reception characteristic value for respective radio waves. The first radio base station determines the radio base station to which each of the mobile stations should connect, according to the first reception characteristic value, and classifies the mobile stations into a first mobile-station group and a second mobile-station group according to the second characteristic values. The first radio base station specifies a correction value according to the distribution of differences in the first reception characteristic value so as to reduce the sum of the number of mobile stations that belong to the second mobile-station group and that should connect to the first radio base station and the number of mobile stations that belong to the first mobile-station group and that should connect to second radio base stations.
