Abstract
To improve throughput of the whole system while reducing power consumption. In a mobile communication system comprising a mobile station apparatus and a base station apparatus, the base station apparatus creates an interference information table based on channel quality of an uplink channel, and at the same time, transmitting the interference information indicator table to the mobile station apparatus, and the mobile station apparatus determines a state of interference in an uplink frequency band based on the interference information indicator table, determines a frequency band of a measurement pilot channel, which is a pilot channel used to determine received quality, and make a request to the base station apparatus for a transmission resource. For example, the mobile station apparatus determines a frequency band with lowest interference among the uplink frequency bands as a frequency band of the measurement pilot channel.
