Abstract: 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, a method includes 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, a first transmit power to the first subframe j and a second transmit power to the second subframe i. The first transmit power is less than or equal to a first power upper limit. A sum of the first transmit power and the second transmit power is less than or equal to a first threshold. 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 threshold.
