Abstract:
1. A radio communication system, comprising: mobile terminals and plural base stations each of which communicates with mobile terminals existing in a subordinate cell, wherein each of the base stations includes: an interference power measurement portion which measures a total interference power received from mobile terminals existing in adjacent cells; a comparison portion which compares the total interference power with a preset value; an interference reduction request portion which issues a request to reduce interference to base stations of the adjacent cells based on a result of the comparison; and a control portion which notifies mobile terminals existing in a subordinate cell of transmission power control information when said request to reduce interference is received from a base station of an adjacent cell, so as to reduce the interference, and each of the mobile terminals includes a reception portion which receives said transmission power control information from said base station that is requested to reduce the interference from the base station of the adjacent cell and reduces a transmission power when said transmission power control information is received.
