An incoming direction detecting part (106) causes an antenna directivity control part (102) to control antennas in an adaptive manner so as to narrow the range in which to transmit data. DPCH transmission power control parts (111-1 to 111-n) perform, based on request signals, received from radio receiving parts (104-1 to 104-n), for raising or reducing the transmission power, a transmission power control of DPCH transmission signals. Power determining parts (112-1 to 112-n) determine, from the thus controlled transmission power, how much amount the transmission power was raised or reduced, and then output signals based on that amount to adaptive modulation control parts (113-1 to 113-n). The adaptive modulation control parts (113-1 to 113-n) perform, based on the signals received from the power determining parts (112-1 to 112-n), an adaptive modulation control of the packet data of the HS-DSCH. This can prevent errors from occurring in received signals due to an erroneous adaptive modulation. |
