Abstract:
1. A transmission rate control method of controlling a transmission rate of user data to be transmitted from a mobile station via an uplink, used in a communication system in which an absolute rate grant channel for designating a maximum allowable transmission rate and a relative rate grant channel for adjusting the maximum allowable transmission rate are to be transmitted from a serving cell, and the relative rate grant channel is to be transmitted from a non serving cell, wherein when the serving cell performing a scheduling control in the uplink of the mobile station transmits, to the mobile station, the absolute rate grant channel for designating the maximum allowable transmission rate common in the serving cell, and the mobile station determines the transmission rate of the user data based on the absolute rate grant channel provided by the serving cell, the non-serving cell does not transmit the relative rate grant channel.
