Abstract
Methods for controlling power in a wireless communication system can reduce system power use. Further methods can control power of a HS-SCCH. When a controller (e.g., node B) receives a transmit power control (TPC) command from a UE, it can differentially controls transmission power of part-1 and part-2 constituting a sub-frame of HS-SCCH to be suitable to each UE on the basis of the power control of DL DPCH constructed in each UE and power control of CPICH transmitted (e.g., equally) to every UE. Since the transmission power of HS-SCCH is controlled by differentiating part-1 and part-2, the inter-cell interference can be reduced or minimized and the power of the node B can be effectively used.
