Abstract:
When time at present is included in a high-traffic time period, an interference determining unit (37) determines that there is a possibility that a downlink signal to be received by any wireless terminal has interference with a pilot signal transmitted from a wireless base station. A pilot signal transmission control unit (40) controls the transmission of the pilot signal, which is included in an OFDMA frame or an OFDM frame. When it is determined that there is the possibility of interference, the pilot signal transmission control unit (40) stops the transmission of the pilot signal or reduces power of the pilot signal in a whole or a portion of a user data area.
