Abstract:
1. A method for realizing power control on a control channel, transmission of which is discontinuous resulting in a discontinuously transmitted control channel, the method comprising: measuring an interval between a current transmission of the discontinuously transmitted control channel and a last transmission of the discontinuously transmitted control channel, wherein, the interval is a time interval; comparing the time interval with a preset threshold to produce a comparison result, wherein the preset threshold is set by a radio network controller based on radio control channel correlation; and determining a power control mode of the current transmission of the discontinuously transmitted control channel based on the comparison result, wherein the determining of the power control mode of the current transmission of the discontinuously transmitted control channel based on the comparison result comprises: wherein the use of the open loop power control or the initial transmission power for the current transmission of the discontinuously transmitted control channel when the time interval is larger than or equal to the preset threshold ensures that a transmission power of the discontinuously transmitted control channel is set high enough to guarantee quality of the discontinuously transmitted control channel but also that the transmission power of the discontinuously transmitted control channel is set low enough not to interfere with other control channels.
