Abstract  Abstract

A method for controlling a power of a shared control channel for high speed downlink shared channel (HS-SCCH) in a system adopting a high speed downlink packet access (HSDPA) technique is disclosed which can control power of HS-SCCH by using the DPCH channel configured in each UE. Especially by transmitting power of each sub-frame suitably for each UE and by setting suitable transmission power of HS-SCCH according to whether it is in soft handover and according to whether it is a primary cell in soft handover an inter-cell interference can be reduced and power of the base station can be effectively used.
