摘要
The mobile station 2-1 determines whether a current maximum transmission rate is sufficient or not in a predetermined cycle by using a maximum transmission rate R indicated by a pointer, a volume Q of data accumulated in the buffer 22-1 and a requested delay T determined according to service of data. The mobile station 2-1 transmits a determination result as an RR signal in a predetermined control signal field within an uplink E-DPCH to the base station 1. The base station 1 receives an RR signal from the mobile station 2-1, determines an increment/decrement of the maximum transmission rate allowed for the mobile station 2-1 to use such that a noise rise fails to exceed a predetermined threshold value and notifies the mobile station 2-1 of the determination as an RG signal by a downlink E-DPCCH. The mobile station 2-1 ups or downs the position of the pointer according to the RG signal.
