Abstract:
To improve the delivery probability of a random access channel and increase the information amount notified on the random access channel. In a mobile communication system in which a mobile station apparatus and base station apparatus perform multicarrier communication with each other, the mobile station apparatus sets transmission control information about a random access channel based on a state of the mobile station apparatus in transmitting the random access channel, and the base station apparatus determines the state of the mobile station apparatus based on the transmission control information notified on the random access channel, and performs optimal scheduling corresponding to the state of the mobile station apparatus.
