Uplink channel transmission method, ue, and base station

Abstract

The present invention provides an uplink channel transmission method, UE, and a base station, and relates to the communications field. The method includes: determining, by the UE, n first channels and m second channels; allocating transmit power to L uplink channels according to a maximum uplink transmission time difference between the n first channels and the m second channels, where the L uplink channels include at least k second channels in the m second channels; and transmitting the L uplink channels. The first channel is an uplink channel corresponding to a first cell on a first time unit numbered i, and duration of the first time unit is a first TTI. The second channel is an uplink channel corresponding to a second cell on a second time unit numbered j, and duration of the second time unit is a second TTI. The second TTI is shorter than the first TTI.
