Method and device for processing power parameters

The invention discloses a method and a device for processing power parameters. The method comprises the following steps: user equipment (UE) acquires the power relationship parameter and the ratio of a first kind of sub-frames and a second kind of sub-frames, wherein the power relationship parameter is used for indicating the power relationship of the first kind of sub-frames and the second kind of sub-frames; and the UE performs data demodulation operation and/or channel measurement operation on the first kind of sub-frames by utilizing the power relationship parameter and the ratio. Through the method and the device provided by the invention, the problem that the data demodulation or channel measurement of the UE is inaccurate due to different power configurations of different kinds of sub-frames in correlation techniques is solved, and the system performance is improved.
