To provide a mobile communications system which can perform a rate control efficiently by reducing the amount of messages for performing the rate control.

In a base station transceiver part 3, a control is applied so that a noise rise may become below a predetermined level in a line quality measuring part 37, resources on a radio space which is divided into a group in a resources distribution part 38 for the whole group and which can be acted for every mobile terminal is decided, and the amount of data which can transmit from a TFCS for every terminal group in a TFC allocation part 39 for the whole terminal group corresponding maximum TFC is determined. Terminal group information is formed in the terminal group information transmitting part 40, it transmits by a dispersion processing part 42 using an ICH which is a common channel. The TFC information judged in a judgment TFC information transmitting part 41 is multiplexed to physical channels, such as an SCCPCH, etc. , and it is transmitted to them by a dispersion processing part 43.
