FIG. 6 is a schematic diagram of a hardware structure of a terminal for implementing the embodiments of this disclosure. The terminal 600 includes but is not limited to components such as a radio frequency unit 601, a network module 602, an audio output unit 603, an input unit 604, a sensor 605, a display unit 606, a user input unit 607, an interface unit 608, a memory 609, a processor 610, and a power supply 611. A person skilled in the art may understand that the structure of the terminal shown in FIG. 6 does not constitute a limitation on the terminal. The terminal may include more or fewer components than those shown in the figure, or some components are combined, or component arrangements are different. In this embodiment of this disclosure, the terminal includes but is not limited to a mobile phone, a tablet computer, a notebook computer, a palmtop computer, an in-vehicle terminal, a wearable device, a pedometer, or the like.

The processor 610 is configured to, in a case that pieces of UCI of different priorities are to be transmitted on a same target channel, code the pieces of UCI of different priorities respectively.

The radio frequency unit 601 is configured to transmit the pieces of UCI of different priorities on the target channel after coding the pieces of UCI respectively.

A priority of the UCI is determined by a target parameter of DCI and/or information contained in the UCI, and the DCI is used to indicate DCI corresponding to transmission of the UCI.
