- the media signal processing unit 54 is configured to perform media signal processing, and then transmit an uplink signal to the MAC layer processing unit 53 and transmit a downlink signal to the base station interface 55. ! RU
- the base station interface 55 is an interface with the radio base station NodeB.
- the base station interface 55 transfers the uplink signal transmitted from the radio base station NodeB to the MAC layer processing unit 53 (or media signal processing unit 54), and the MAC layer processing unit 53 (or media signal processing unit). 54)
- the power is also configured to forward the transmitted downlink signal to the radio base station NodeB.
- the call control unit 56 is configured to perform radio resource management processing, channel setting and release processing by layer 3 signaling, and the like.
- radio resource management includes call admission control, node over control, and the like.
- the scheduling unit 12313 of the radio base station NodeB receives a common AG (common absolute transmission rate control signal used in common absolute transmission rate control) on the common AGCH. It was configured to send and send individual AG (individual absolute transmission rate control signal used in individual absolute transmission rate control) on individual AGCH.
- common AG common absolute transmission rate control signal used in common absolute transmission rate control
- the scheduling unit 12313 of the radio base station NodeB uses the common AG (common absolute transmission) on the AGCH without distinguishing between the common AGCH and the individual AGCH.
- Speed control signal and individual AG (individual absolute transmission speed control signal).
- the scheduling unit 12313 of the radio base station NodeB uses the common RG (common relative transmission rate control) on the RGCH without distinguishing between the common RGCH and the individual RGCH.
- Common relative transmission rate control signal and individual RG (individual relative transmission rate control signal used in common relative transmission rate control) may be transmitted.
- the E-TFC selection unit 33cl of the mobile station UE receives the first transmission rate specified by the common AG received via the AGCH and the individual RG received via the dedicated RGCH or RGCH.
- the first transmission rate and the second transmission rate are compared with the second transmission rate determined based on the transmission rate in the uplink, and set to the uplink transmission rate.
- a transmission rate control method and a mobile station that can control QoS for each mobile station UE while eliminating the influence on the radio capacity in the downlink as much as possible. can do.
