<p>After a channel is established, CL-TPC section 162 calculates a transmit power value based on a TPC command and carries out closed-loop transmit power control. At the same time, OL-TPC section 161 calculates a transmit power value based on a reception level and compensation value calculation section 164 calculates a compensation value based on a difference between the transmit power value output from CL-TPC section 162 and that of OL-TPC section 161. After the compensation value is confirmed, mode switching section 165 switches between switches 167 and 169 and open-loop transmit power control is performed using a value obtained by adding the compensation value to the reception-level-based transmit power value. This makes it possible to compensate a reception level measurement error without the need to maintain high reception measurement accuracy, and further handle cases where high-speed fading or intense interference emerges. <IMAGE></p> |
