    摘要： A transmission rate control method according to the present invention includes: determining, at the radio base station NodeB, a maximum granted value that can be notified to the mobile station UE, in accordance with a throughput at which the uplink user data transmitted from the mobile station UE to the radio base station NodeB is successfully received at a point of time; calculating, at the radio base station NodeB, as an allowable value to be notified to the mobile station UE, a granted value not more than the maximum granted value; notifying, from the radio base station NodeB to the mobile station UE, the granted value calculated at the radio base station NodeB, by using a transmission rate control channel; and transmitting, from the mobile station UE, the uplink user data, at the transmission rate corresponding to the granted value notified from the radio base station NodeB.

    摘要： A radio communication system includes: a serving cell (for example, cell A functional unit 120) configured to transmit, to a radio terminal 10, an AG for directly specifying an uplink user data transmission rate and an RG for relatively specifying the uplink user data transmission rate; and a non-serving cell (for example, cell B functional unit 130) configured to transmit the relative grant to the radio terminal 10 without transmitting the absolute grant. The non-serving cell includes an RG controlling unit 133 configured to control a transmission interval of an RG for instructing a decrease of the uplink user data transmission rate.
