TRANSMISSION POWER CONTROL METHOD, TPC COMMAND TRANSMISSION METHOD, AND RADIO COMMUNICATION DEVICE

摘要

In a radio communication system where A-DPCH (Associated-Dedicated Physical Channel) to which soft hand-over is applied and HS-DPCCH (High Speed-Dedicated Physical Control Channel) to which hard hand-over is applied are mixed, in order to perform appropriate transmission power control of the HS-DPCCH, an HO judging section 11 judges whether the A-DPCH is in a soft hand-over state, and a transmission radio section 23, when the A-DPCH is not in the soft hand-over state, performs transmission power control of the HS-DPCCH according to a TPC command for the A-DPCH transmitted on the A-DPCH, and when the A-DPCH is in the soft hand-over state, performs transmission power control of the HS-DPCCH according to a TPC command for the HS-DPCCH transmitted on the HS-DPCCH. <IMAGE>
