ABSTRACT:
Reception SIR calculation section107calculates a reception SIR using a value obtained by averaging interference signal power over several immediately preceding consecutive slots. Reference value decision section109decides whether the reception SIR is greater than a reference value or not. In the case where the count of desired signal power stored in power value storage section108satisfies a count necessary for averaging and at the same time the reception SIR is not greater than the reference value, TPC creation section110creates a TPC to instruct a decrease of transmit power and creates a TPC to instruct an increase of transmit power otherwise. This allows the base station to constantly receive signals of sufficient quality and perform efficient communications.
