Abstract  Abstract

The embodiment of this invention relates to the radio communication technical field specifically to a method a system and a device for sending power control information and controlling power. The utility model is for solving the problem that the terminal cannot control the PDCCH power when the TPC instruction is reused in the prior art so as to degrade the PDCCH power accuracy. The method provided in the embodiment of this invention comprises: a terminal judges if there is a non-TCP instruction in a sending TPC domain of the first DCI format information after receiving the first DCI format information; after the terminal receives the non-TCP instruction in the TPC domain of the first DCI format information and receives the second DCI format information in a downlink sub-frame of the first DCI format information the terminal controls the PUCCH power with the TPC instruction in the second DCI format information. With the method provided in the embodiment of this invention the PUCCH power accuracy and the terminal performance can be increased and improved.
