Abstract
A method and apparatus for realizing power control on a control channel including measuring the interval between the current control channel transmission and the last control channel transmission; comparing the measured interval with a preset threshold, and if the interval is larger than or equal to the preset threshold, carrying out the current control channel transmission by using the initial transmit power, or controlling the current control channel transmission by using the open loop power control and, otherwise, controlling the current control channel transmission by using the closed loop power control. When the control channel is an uplink control channel, it may be determined whether a compensation for path loss variance should be added based on the closed loop power control according to a related command, so as to enable that the power control can be provided effectively when the control channel transmission is discontinuous.
