Method and apparatus for transmitting/receiving wireless signal in wireless communication system

A communication apparatus configured to transmit control information in a wireless communication system, the communication apparatus comprising:

• at least one transceiver;
• at least one processor;
• and
• at least one computer memory operably connected to the at least one processor and storing instructions that, based on being executed by the at least one processor, perform operations comprising:
• determining a plurality of physical uplink control channel (PUCCH) resources, within a single time slot, that are associated with a respective plurality of uplink control information (UCI);
• determining a first PUCCH resource which has an initial symbol that is earliest among initial symbols of the plurality of PUCCH resources in the single time slot;
• based on the first PUCCH resource not overlapping in time with any other PUCCH resource among the plurality of PUCCH resources:
• transmitting, on the first PUCCH resource via the at least one transceiver, first UCI associated with the first PUCCH resource;
• and
• based on the first PUCCH resource overlapping in time with one or more second PUCCH resources, among the plurality of PUCCH resources, whose initial symbols occur after the initial symbol of the first PUCCH resource:
• determining at least one multiplexing PUCCH resource for at least one multiplexed UCI;
• and
• transmitting, via the at least one transceiver, a multiplexed UCI on a multiplexing PUCCH resource, based on determining the at least one multiplexing PUCCH resource for the at least one multiplexed UCI,
• wherein determining the at least one multiplexing PUCCH resource comprises:
• determining a first multiplexing PUCCH resource for multiplexing (1) the first UCI associated with the first PUCCH resource and (2) one or more second UCI associated with the one or more second PUCCH resources;
• and
• based on the first multiplexing PUCCH resource overlapping in time with one or more third PUCCH resources among the plurality of PUCCH resources:
• determining a second multiplexing PUCCH resource for multiplexing (1) UCI associated with the first multiplexing PUCCH resource and (2) one or more third UCI associated with the one or more third PUCCH resources.

A processing device configured to control a communication apparatus to transmit control information in a wireless communication system, the processing device comprising:

• at least one processor;
• and
• at least one computer memory operably connected to the at least one processor and storing instructions that, based on being executed by the at least one processor, perform operations comprising:

• determining a first PUCCH resource which has an initial symbol that is earliest among initial symbols of the plurality of PUCCH resources in the single time slot;
• based on the first PUCCH resource not overlapping in time with any other PUCCH resource among the plurality of PUCCH resources:
• transmitting, on the first PUCCH resource, first UCI associated with the first PUCCH resource;
• and
• based on the first PUCCH resource overlapping in time with one or more second PUCCH resources, among the plurality of PUCCH resources, whose initial symbols occur after the initial symbol of the first PUCCH resource:
• determining at least one multiplexing PUCCH resource for at least one multiplexed UCI;
• and
• transmitting a multiplexed UCI on a multiplexing PUCCH resource, based on determining the at least one multiplexing PUCCH resource for the at least one multiplexed UCI,
• wherein determining the at least one multiplexing PUCCH resource comprises:
• determining a first multiplexing PUCCH resource for multiplexing (1) the first UCI associated with the first PUCCH resource and (2) one or more second UCI associated with the one or more second PUCCH resources;
• and
• based on the first multiplexing PUCCH resource overlapping in time with one or more third PUCCH resources among the plurality of PUCCH resources:
• determining a second multiplexing PUCCH resource for multiplexing (1) UCI associated with the first multiplexing PUCCH resource and (2) one or more third UCI associated with the one or more third PUCCH resources.
