The wireless communication system, a wireless communication method and a base station

Object of the present invention is to provide a radio communication system to appropriately control the transmission rate of the uplink user data, a wireless communication method and a base station. In the wireless terminal (10) transmits uplink user data via the E-DPDCH to the base station (100) a wireless communication system, a base station (100) has a scheduling unit (120a), when the wireless terminal (10) not to assign to the radio terminal (10 when) the transmission rate of uplink user data transmitted to the wireless terminal (10) for instructing to reduce the transmission allocated to the wireless terminal (10) of the transmission rate decrease data transmission rate.
