Uplink sending power determining method and user equipment

The embodiment of the invention provides an uplink sending power determining method and user equipment. One or more sending situations in PUCCH, PUSCH and SRS on other cells except an auxiliary cell in a sub frame corresponding to a precursor to be sent on the auxiliary cell are determined through the user equipment, and the user equipment can determine the uplink sending power of the user equipment according to the determined sending situations. By means of the uplink sending power determining method and the user equipment, the problem of determining the uplink sending power of the user equipment when the auxiliary cell executes random access without the user equipment in the prior art is solved.
