Abstract
A data transmission method includes: 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 a first link; and sending, by the UE, the control channel and the data channel in a same subframe.
Claims20
A data transmission method, comprising:
- obtaining, by an apparatus, a maximum transmit power;
- determining, by the apparatus, a transmit power of a data channel based on a sum of the maximum transmit power and a first additional item, wherein the first additional item is determined based on a bandwidth of a control channel and a bandwidth of the data channel;
- determining, by the apparatus, a transmit power of a control channel based on a sum of the maximum transmit power and a second additional item, wherein the second additional item is determined based on the bandwidth of the control channel and the bandwidth of the data channel;
- and
- sending, by the apparatus, the control channel and the data channel in a same subframe.
An apparatus, comprising:
- at least one processor;
- and
- a non-transitory computer-readable storage medium coupled to the at least one processor and storing programming instructions for execution by the at least one processor, wherein the programming instructions instruct the at least one processor to:
- obtain a maximum transmit power;
- determine a transmit power of a data channel based on a sum of the maximum transmit power and a first additional item, wherein the first additional item is determined based on a bandwidth of a control channel and a bandwidth of the data channel;
- determine a transmit power of the control channel based on a sum of the maximum transmit power and a second additional item, wherein the second additional item is determined based on the bandwidth of the control channel and the bandwidth of the data channel;
- and
- cause a transceiver to send the control channel and the data channel in a same subframe.
A non-transitory computer readable storage medium, comprising computer program codes which when executed by at least one processor cause a terminal device to perform the steps of:
- obtaining a maximum transmit power;
- determining a transmit power of a data channel based on a sum of the maximum transmit power and a first additional item, wherein
- the first additional item is determined based on a bandwidth of a control channel and a bandwidth of the data channel;
- determining a transmit power of a control channel based on a sum of the maximum transmit power and a second additional item, wherein
- the second additional item is determined based on the bandwidth of the control channel and the bandwidth of the data channel;
- and
- sending the control channel and the data channel in a same subframe.
