Abstract  Abstract

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.
