Mobile Station Device, Base Station Device, and Transmission Rate Control Method

摘要

A mobile device, a base station device, and a transmission rate control method for preventing the reception power at all the base station devices of an active set from exceeding an RoT threshold and preventing an excessive load. A transmission rate command acquiring section ( 304 ) of the mobile station device ( 300 ) acquires transmission rate commands transmitted from the base station devices ( 100 a to 100 c) from a received signal. A transmission rate determining section ( 305 ) determines the transmission rate of the uplink channel according to the transmission rate command. A DOWN monitoring section ( 306 ) monitors the transmission rate command from the base station devices ( 100 b, 100 c) of a non-primary cell and monitors the amount of "DOWN". The DOWN monitoring section ( 306 ) judges that the load is heavy in a base station device where the amount of "DOWN" is large. If there is a base station device where the load is heavy, an another-cell load information creating section ( 307 ) creates another-cell load information for inhibiting creation of AG by the base station device ( 100 a ) of the primary cell.
