Patent ID: 8345631

Claim:
A mobile communication system comprising: a base station; and a plurality of mobile stations that are under control of the base station and that start a Gating operation for terminating a transmission operation through a physical channel if no more data is to be transmitted to the base station during High Speed Uplink Packet Access (HSUPA) communication with the base station through the physical channel, the base station allocating a transmission rate to each of the plurality of mobile stations, the base station comprising: a Received Total Wide Band Power (RTWP) measurement unit that measures RTWP of the base station; a monitoring circuit that monitors a start and a removal of a Gating state by each of the plurality of mobile stations; a threshold setting circuit that, when a mobile station of the plurality of mobile stations starts the Gating operation and thereby enters the Gating state, lowers a threshold by an amount of an offset, which is equivalent to a difference between a transmission rate of the mobile station during the HSUPA communication and a transmission rate of the mobile station during the Gating operation; and a scheduling circuit that allocates a transmission rate, which is equivalent to a difference between the RTWP of the base station and the threshold, to a mobile station other than the mobile station in the Gating state among the plurality of mobile stations if the RTWP of the base station is less than the threshold.
