ABSTRACT:
It is an object of the present invention to provide a control system making it possible to maintain communication quality, decrease transmission delay, and simultaneously connect with numerous mobile stations40. The present invention is a control system for controlling the information rate through a downlink shared channel (DSCH) addressed to the mobile stations40, which is provided with a transmission power control information receiving unit23for receiving the transmission power control information for a downlink dedicated channel (A-DPCH) transmitted through an uplink dedicated channel (DPCH), transmission power control information accumulating unit23for accumulating the transmission power control information for the downlink dedicated channel, and information rate controlling unit22for controlling the information rate through a downlink shared channel addressed to the mobile stations40according to the accumulated value of the transmission power control information for the downlink dedicated channel.
