FIELD: radio engineering, communication.SUBSTANCE: invention relates to radio communication. A trigger information reporting determination unit (108) performs threshold discrimination, where PHR_pucch, which is calculated by PHR_control calculation unit (106), is compared with a threshold value that depends on the multiplexing method indicated by the instruction given by the base station. Specifically, in a TDM transmission mode, trigger information is reported if PHR_pucch>X1[dB/mW] is satisfied. On the other hand, in an FDM transmission mode, the trigger information is reported if PHR_pucch<Y1[dB/mW] is satisfied. Based on a result of the threshold discrimination, the trigger information reporting determination unit (108) determines whether to report the trigger information.EFFECT: invention provides a radio communication mobile station apparatus, a radio communication base station apparatus and a radio communication method, which make it possible to correctly switch between transmission modes for a PUSCH and a PUCCH while preventing signalling overhead from increasing; a transmission mode setting unit (107) detects an instruction given by a base station, the instruction indicating a multiplexing method for a PUSCH and a PUCCH.23 cl, 17 dwg |
