1. A method of transmitting hybrid automatic repeat request-acknowledgment (HARQ-ACK) information by a communication device in a wireless communication system, the method comprising:
in a state in which a first physical uplink control channel (PUCCH) resource associated with first uplink control information (UCI) overlaps with a plurality of PUCCH resources associated with a plurality of HARQ-ACK payloads in a time domain, determining a third PUCCH resource for multiplexing the first UCI and a first HARQ-ACK payload associated with a second PUCCH resource being one of the plurality of PUCCH resources, based on the first HARQ-ACK payload and the first UCI; and
transmitting the first HARQ-ACK payload and the first UCI in the third PUCCH resource,
wherein the remaining HARQ-ACK payloads except for the first HARQ-ACK payload among the plurality of HARQ-ACK payloads are not transmitted in the third PUCCH resource.
2. The method according to claim 1 , wherein the second PUCCH resource is an earliest PUCCH resource among the plurality of PUCCH resources.
3. The method according to claim 1 , wherein the second PUCCH resource is a PUCCH resource associated with a specific type of downlink channel among the plurality of PUCCH resources.
4. The method according to claim 3 , wherein the specific type of downlink channel is a first type of channel between the first type of channel and a second type of channel, and
wherein the first type of channel has a lower quality of service (QoS) requirement than the second type of channel.
5. The method according to claim 1 , further comprising:
in a state in which the third PUCCH resource overlaps with another PUCCH resource in the time domain, transmitting the plurality of HARQ-ACK payloads respectively in the plurality of PUCCH resources, while dropping transmission of the first UCI in the first PUCCH resource.
6. The method according to claim 1 , wherein the plurality of PUCCH resources do not overlap with each other in the time domain.
7. A communication device for transmitting hybrid automatic repeat request-acknowledgment (HARQ-ACK) information in a wireless communication system, the communication device comprising:
at least one transceiver;
at least one processor; and
at least one computer memory operatively coupled to the at least one processor and storing instructions which when executed, cause the at least one processor to perform operations comprising:
