Abstract: An uplink transmission method includes that in a case that a first channel overlaps a second channel in time, the second channel overlaps a third channel in time, and a priority corresponding to the third channel is higher than a priority corresponding to the first channel and a priority corresponding to the second channel, a terminal performs a first operation. The first operation includes: multiplexing first uplink control information on the third channel for transmission; or not multiplexing the first uplink control information on the third channel for transmission. The first uplink control information is uplink control information carried on the first channel.
