    摘要: In a radio communication system, each of user terminals together with transmitting a data signal to a base station using different data transmission band frequencies that are assigned by a base station, performs time-division multiplexing of a pilot signal with the data signal and transmit the resulting signal to the base station. A resource management unit of the base station decides pilot transmission bands for each user terminal so that the pilot transmission band covers the data transmission band for each user terminal by frequency offset, and instructs the user terminal to transmit pilot signals using the decided pilot transmission band frequencies. Thereby the base station can estimate channel for each frequency of the data transmission band using the pilot signal.

    摘要: Upon handover, a mobile station receives, from the movement origin base station, information on the movement destination base station and information relating to a sequence to be used for transmitting a random access signal to the movement destination base station. The mobile station receives a synchronization channel signal transmitted from the movement destination base station. The mobile station transmits the random access signal to the movement destination base station at a timing offset by a prescribed period from a timing of receiving a synchronization channel and at a frequency corresponding to that of the synchronization channel. A position of the timing/frequency used for transmitting the random access signal for the handover is used exclusively by the random access signal transmitted from the mobile terminal for which a handover is being performed or is used exclusively at the same time by a plurality of mobile stations for which handovers are performed.
