Abstract: In an embodiment, a method includes, in response to a user equipment (UE) sending data to a first network side device over a first channel and to a second network side device over a second channel, determining that the first channel separately overlaps the second channel and a third channel. The method further includes allocating, according to priorities of the first channel and the second channel, first transmit power to the first subframe j and second transmit power to the second subframe i, where the first transmit power is less than or equal to a first power upper limit, where a sum of the first transmit power and the second transmit power is less than or equal to a first threshold, and where a sum of third transmit power of the third subframe i+1 and the first power upper limit is less than or equal to a preset second threshold.

Abstract: Embodiments of the present invention provide a method for an uplink softer handover and a user equipment. The method includes: detecting signal quality or signal strength of an intra-frequency neighboring cell; if there is an intra-frequency neighboring cell whose signal quality or signal strength meets a first threshold, reporting, through a physical control channel or by using scheduling information, related information of the intra-frequency neighboring cell that meets the first threshold to a base station to which a user equipment belongs.
