    摘要: Embodiments of the present invention provide a data transmission method, including: obtaining, by user equipment UE, a maximum transmit power; determining, by the UE, a transmit power of a data channel and/or a transmit power of a control channel based on the maximum transmit power and a first parameter, where the first parameter includes at least one of the following: a bandwidth of the data channel, a bandwidth of the control channel, or a carrier type of a carrier of the first link; and sending, by the UE, the control channel and the data channel in a same subframe. Therefore, in the embodiments of the present invention, when the data channel and the control channel are sent in the same subframe, the transmit power of the data channel and the transmit power of the control channel can be determined based on at least one of the maximum transmit power, the bandwidth of the data channel, the bandwidth of the control channel, or the carrier type of the carrier of the first link, to properly determine the transmit powers of control information and data.
