Mobile communication system, mobile station apparatus, base station apparatus, and random access channel transmission method

摘要

An object of the present invention is to improve the delivery probability of a random access channel and increase the amount of information notified through the random access channel. In a mobile communication system that performs multicarrier communication between a mobile station apparatus and a base station apparatus, the mobile station apparatus uses a random access channel based on a state of the mobile station apparatus when transmitting the random access channel. The base station apparatus determines the state of the mobile station apparatus based on the transmission control information notified through the random access channel, and performs optimal scheduling according to the state of the mobile station apparatus. .
