1. An uplink transmission method, comprising:
canceling a transmission of part or all of time domain symbols in a first uplink transmission according to a starting symbol of which the transmission of the first uplink transmission is cancelled in a case where the first uplink transmission overlaps with a second uplink transmission in a time domain, wherein the first uplink transmission corresponds to a first priority, the second uplink transmission corresponds to a second priority, and the first priority is lower than the second priority; and
transmitting a third uplink transmission through time domain symbols of which the transmission is cancelled in the first uplink transmission in a case where a set condition is satisfied;
wherein the starting symbol of which the transmission of the first uplink transmission is cancelled is determined according to a predefined duration, the predefined duration is determined according to types of the second uplink transmission or the third uplink transmission;
wherein the third uplink transmission corresponds to the first priority, and a scheduling type of the third uplink transmission is a semi-static scheduling; and
wherein the set condition comprises:
the predefined duration before a starting symbol of the third uplink transmission being later than a starting symbol or an end symbol of downlink control information corresponding to the second uplink transmission;
wherein the first uplink transmission or the third uplink transmission comprises: a physical uplink control channel (PUCCH) for transmitting hybrid automatic repeat request-acknowledgement (HARQ-ACK) information with the first priority, a PUCCH for transmitting a scheduling request with the first priority, a PUCCH for transmitting periodic-channel state information with the first priority, a physical uplink shared channel (PUSCH) for transmitting channel state information with the first priority, a PUCCH for transmitting a beam failure recovery (BFR) with the first priority, a dynamically scheduled PUSCH for transmitting uplink data with the first priority, or a semi-statically scheduled PUSCH for transmitting uplink data with the first priority; and
wherein the second uplink transmission comprises: a PUCCH for transmitting a HARQ-ACK with the second priority, a PUCCH for transmitting a scheduling request with the second priority, a PUSCH for transmitting channel state information with the second priority, a PUCCH for transmitting a BFR with the second priority, a dynamically scheduled PUSCH for transmitting uplink data with the second priority, or a semi-statically scheduled PUSCH for transmitting uplink data with the second priority.
