Uplink control information transmission method and apparatus, and communication device

An information transmission method, comprising:

• based on that a first physical uplink control channel, PUCCH, carrying a first uplink control information, UCI, overlaps, in a time domain, with each of a plurality of second PUCCHs carrying hybrid automatic repeat request-acknowledgements, HARQ-ACKs, and each of the plurality of second PUCCHs carrying HARQ-ACKs does not overlap with each other in the time domain, determining, by a network device, that the first UCI is dropped;
• or
• based on that the first PUCCH carrying the first UCI overlaps, in the time domain, with a second PUCCH carrying a first HARQ-ACK, determining, by the network device, that the first UCI is dropped if it is determined that a third PUCCH carrying the first HARQ-ACK and the first UCI overlaps, in the time domain, with a fourth PUCCH carrying a second HARQ-ACK;
• wherein the first UCI is of a type of UCI other than the HARQ-ACK, or when the first UCI comprises the HARQ-ACK, a priority of the HARQ-ACK in the first UCI is lower than a priority of the HARQ-ACK carried on the second PUCCH.

A communication device, comprising:

• a memory, configured to store a program instruction;
• and
• a processor, configured to call the program instruction stored in the memory to execute according to an obtained program:
• based on that a first physical uplink control channel, PUCCH, carrying a first uplink control information, UCI, overlaps, in a time domain, with each of a plurality of second PUCCHs carrying hybrid automatic repeat request-acknowledgements, HARQ-ACKs, and each of the plurality of second PUCCHs carrying HARQ-ACKs does not overlap with each other in the time domain, dropping the first UCI;
• or
• based on that the first PUCCH carrying the first UCI overlaps, in the time domain, with a second PUCCH carrying a first HARQ-ACK, dropping the first UCI, if it is determined that a third PUCCH carrying simultaneously the first HARQ-ACK and the first UCI overlaps, in the time domain, with a fourth PUCCH carrying a second HARQ-ACK;
• wherein the first UCI is of a type of UCI other than the HARQ-ACK, or when the first UCI comprises the HARQ-ACK, a priority of the HARQ-ACK in the first UCI is lower than a priority of the HARQ-ACK carried on the second PUCCH.
