<P>PROBLEM TO BE SOLVED: To provide a communication technique more immune to velocity/fading. <P>SOLUTION: A radio base station allocates a plurality of pairs of time slots in one frame to a radio terminal, calculates reception weight in each of the allocated uplink time slots based on an uplink signal transmitted from the radio terminal, and controls first transmission weight for transmitting a downlink signal using a downlink time slot with the fastest transmission time, based on the reception weight of the uplink time slots, a first time difference between the respective uplink time slots, and a second time difference between the time slot with the latest reception time of the uplink signal in the frame among the allocated uplink time slots and the time slot with the fastest reception time of the downlink signal in the frame among the allocated downlink time slots. <P>COPYRIGHT: (C)2012,JPO&INPIT |
