1. An uplink control information (UCI) transmission method, comprising:
in a case that pieces of UCI of different priorities are to be transmitted on a same target channel, coding, by a terminal, the pieces of UCI of different priorities respectively and transmitting, by the terminal, the coded pieces of UCI on the target channel, wherein
a priority of the UCI is determined by a target parameter of downlink control information (DCI) and/or information contained in the UCI, the DCI is used to indicate DCI corresponding to transmission of the UCI, and the target channel comprise a physical uplink control channel (PUCCH); wherein
the method further comprises:
in a case that the pieces of UCI of different priorities are coded respectively, using, by the terminal, different code rates for the pieces of UCI of different priorities; and
the method further comprises:
determining, by the terminal, code rates used for the pieces of UCI of different priorities based on a first scaling factor and a code rate corresponding to a PUCCH resource, wherein the first scaling factor is configured by radio resource control (RRC), or indicated by DCI, or defined in a protocol; or
determining, by the terminal, code rates used for the pieces of UCI of different priorities based on code rates that correspond to the pieces of UCI of different priorities configured by radio resource control (RRC).
