Abstract:
1. A power controlling device in a mobile communication system, comprising: a frame error detector for detecting an error from a frame of a predetermined length and for generating an error signal indicating whether an error has been generated; a closed-loop power controller for comparing a threshold with a signal-to-noise ratio (SNR) of each power control group (PCG) in a plurality of periods of a frame and for generating power control information according to the comparison result; an outer-loop power controller for increasing the threshold to generate power control information commanding power increase in response to an error signal indicating the existence of a frame error and for decreasing the threshold to generate power control information commanding power decrease in response to an error signal indicating the absence of a frame error; and an offset controlling unit connected to the outer-loop power controller, for receiving gating information about gated transmission of data in a frame at a predetermined rate and for generating an offset signal indicating an offset corresponding to a changed gating rate if the gating rate is changed, wherein the power is controlled whether or not there is data to be transmitted.
