Abstract

In the case that periodical transmission of transmission signal number-of-sequence quality indicative signal cannot be performed, the number of transmission signal sequences is clarified in association with reception quality information that is generated immediately after the case, and the base station apparatus performs appropriate communication resource allocation. A mobile station apparatus has a feedback information control section 65 that generates feedback information including reception quality information, transmission signal preprocessing information and transmission signal number-of-sequence information, and a radio transmission section 51 that periodically transmits the generated feedback information to the base station apparatus, where when the radio transmission section 51 does not transmit the transmission signal number-of-sequence information with communication resources periodically allocated from the base station apparatus so as to transmit the transmission signal number-of-sequence information, the radio transmission section 51 transmits the transmission signal number-of-sequence information to the base station apparatus with communication resources enabling transmission of the feedback information allocated from the base station apparatus subsequently to the communication resources.
