To provide a wireless communication apparatus for controlling transmission power among complex number sequences aiming at improving throughput while suppressing an increase in amount of calculation.
In the wireless communication apparatus, a standard complex number sequence is used to determine whether or not an amount of interference from wireless communication performed by using an additional complex number sequence with respect to an MS200 which performs wireless communication is smaller than a predetermined prescribed threshold TH(INT)1. Similarly, it is determined whether or not the amount of interference from the wireless communication performed by using the standard complex number sequence with respect to the MS200 for performing wireless communication by using the additional complex number sequence is smaller than a predetermined prescribed threshold TH(INT)2. (ST602) When one of these amounts of interference is smaller than respective prescribed thresholds (ST602, Yes), transmission power control processing is performed (ST603).
