摘要

To implement highly accurate SIR estimation and thereby perform stable transmission power control immediately after starting user communication. A common control circuit has an ISSI value of each sector stored therein. On starting the user communication, the common control circuit outputs to a communication channel circuit for starting the communication the ISSI value corresponding to a sector where the communication is started of the stored ISSI values. The communication channel circuit performs the SIR estimation of a received signal by using the ISSI value and also performs the user communication. The communication channel circuit stores the ISSI value on finishing the communication in the common control circuit in the case where the communication is finished.
