Mobile communication system, base station apparatus, and mobile station apparatus

Abstract

The present invention reduces the amount of control information for specifying the transmission method for simultaneously transmitting the uplink data and the reception quality information as well as the uplink data and the ACK/NACK, reduces delay occurring in changing the transmission method, and realizes the mapping of the uplink data and the reception quality information and that of the uplink data and the ACK/NACK, in compliance with modulation scheme and coding rate of the uplink data specified by the base station apparatus. In the mobile communication system where the base station apparatus allocates, to the mobile station apparatus, resources wherein the base station apparatus transmits, to the mobile station apparatus, control information for specifying a transmission format for the mobile station apparatus to transmit information using the uplink, while the mobile station apparatus simultaneously transmits, to the base station apparatus, the uplink data and the reception quality information based on the specified transmission format in case of having received the control information from the base station apparatus.
