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

摘要

In a radio communication system containing A-DPCH (Associated - Dedicated Physical Channel) to which soft handover is applied and HS-DPCCH (High Speed - Dedicated Physical Control Channel) to which hard handover is applied, it is possible to perform an appropriate transmission power control for the HS-DPCCH. An HO judgment section (11) judges whether the A-DPCH is in the soft handover state. When the A-DPCH is not in the soft handover state, a transmission radio section (23) performs transmission power control for the HS-DPCCH according to a TPC command for the A-DPCH transmitted via the A-DPCH. When the A-DPCH is in the soft handover state, the transmission radio section (23) performs transmission power control for the HS-DPCCH according to a TPC command for the HS-DPCCH transmitted via the HS-DPCCH.
