Method of supporting power control on a DCCH in a base station transceiver system and a base station controller

摘要

There is provided a method of transmitting power control information to a BSC (Base Station Controller) in a BTS (Base station Transceiver System) of a mobile communication system. The BTS receives forward power control (FPC) mode information indicating a low power control from the BSC and transmits the FPC mode information to an MS (Mobile Station). Then, the BTS extracts a QIB (Quality Indicator Bit) that is a power control command in a frame period from a reverse pilot channel received from the MS according to the FPC mode information and determines the status of the QIB. The BTS transmits information requesting the BSC to change a threshold for a power control on a forward DCCH (Dedicated Control Channel) based on the determined QIB status to the BSC.
