ABSTRACT:
A mobile user terminal (UE), which measures downlink channel quality, and which transmits downlink quality information indicating the measured downlink channel quality and an uplink pilot signal to be used for measuring uplink channel quality to a base station (BS), comprises a transmit time control unit (216), which synchronizes transmit time of the downlink quality information and transmit time of the uplink pilot signal relative to each other. And/or the mobile user terminal (UE) comprises a radio transmitting unit (212) which transmits the downlink quality information and the uplink pilot signal by using the same carrier frequency or by using adjacent carrier frequencies selected from among a plurality of preassigned carrier frequencies.
