Interference power measurement apparatus, transmission power control apparatus, and method

摘要

The transmit power control apparatus 20 measures, through the SIR measuring section 101, not only a first SIR (SIR1) value reflecting all interference factors but also a second SIR (SIR2) value stripped of a power value component caused by multipath interference. The control signal formation section 31 forms a signal for controlling transmit power using these two SIRs (SIR1, SIR2). In this case, a control signal is formed for instructing that transmit power should not be allowed to increase/decrease when the ratio of the multipath interference component to all interference components is large and that transmit power should be allowed to increase/decrease when the ratio of the multipath interference component is small.
