    摘要: A wireless base station apparatus to establish a wireless connection with a terminal equipment detects an intensity of a signal transmitted from another terminal equipment; calculates, as transmission power for the terminal equipment, a sum of a first parameter adjusted at an interval of predetermined time and a second parameter taking a value between a predetermined first minimum value and a predetermined first maximum value; sets, as the second parameter, the smaller value of a difference between first target power and the first parameter and the first minimum value when detecting that reception power of the signal transmitted from another terminal equipment is equal to or larger than a predetermined value, and further sets a difference between the first target power and the first minimum value as the first parameter and the first minimum value as the second parameter when the first parameter is adjusted.

    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.
