摘要： In conditions of low data traffic, such as during the night, when transmitting pilots in a downlink radio transmission zone, sub frames are divided into (1) first sub frames that transmit common pilots over a whole transmission band, and (2) second sub frames that transmit common pilots over a specified narrow band of a whole transmission band, where first sub frames are transmitted at a specified period, and second sub frames are transmitted for period of time except the specified period.

摘要： A radio communication system including mobile terminals and plural base stations each of which communicates with mobile terminals existing in a subordinate cell. 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; an interference reduction request portion which issues a request to reduce interference to base stations of the adjacent cells based on the total interference power; and a control portion which notifies mobile terminals existing in a subordinate cell of transmission power control information when the request to reduce interference is received from a base station of an adjacent cell, so as to reduce the interference. Each of the mobile terminals includes a reception portion which receives the transmission power control information from the base station that is requested to reduce the interference from the base station of the adjacent cell.
