Method and device for transmitting and receiving signal in wireless communication system

A device for wireless communication, the device comprising:

• a memory configured to store instructions;
• and
• a processor configured to perform operations by executing the instructions, the operations comprising:
• receiving downlink control information (DCI) for scheduling a physical uplink shared channel (PUSCH);
• and
• transmitting the PUSCH including uplink control channel (UCI) based on UCI resources in the PUSCH,
• wherein the processor performs, based on the UCI resources in the PUSCH, i) a first determination for determining a number of resources for a hybrid automatic repeat request-acknowledgement (HARQ-ACK), and ii) a second determination for determining a number of resources for first channel state information (CSI) after the first determination, and
• wherein, based on that the device is configured to multiplex UCIs with different priorities in the PUSCH, and the UCIs with the different priorities include first HARQ-ACK information with a first priority and second HARQ-ACK information with a second priority lower than the first priority:
• the processor determines a number of resources for the second HARQ-ACK information based on ii) the second determination by taking the second HARQ-ACK information with the second priority as the first CSI.

A method of receiving a signal by a base station (BS) in a wireless communication system, the method comprising:

• transmitting, to a user equipment (UE), downlink control information (DCI) for scheduling a physical uplink shared channel (PUSCH);
• and
• receiving, from the UE, the PUSCH including uplink control channel (UCI) based on UCI resources in the PUSCH,
• wherein the BS performs, based on the UCI resources in the PUSCH, i) a first determination for determining a number of resources for a hybrid automatic repeat request-acknowledgement (HARQ-ACK), and ii) a second determination for determining a number of resources for first channel state information (CSI) after the first determination, and
• wherein, based on that the BS has configured the UE to multiplex UCIs with different priorities in the PUSCH, and the UCIs with the different priorities include first HARQ-ACK information with a first priority and second HARQ-ACK information with a second priority lower than the first priority:
• the BS determines a number of resources for the second HARQ-ACK information based on ii) the second determination by taking the second HARQ-ACK information with the second priority as the first CSI.

A base station (BS), the BS comprising:

• a transceiver;
• and
• a processor configured to control the transceiver to:
• transmit, to a user equipment (UE), downlink control information (DCI) for scheduling a physical uplink shared channel (PUSCH);
• and
• receive, from the UE, the PUSCH including uplink control channel (UCI) based on UCI resources in the PUSCH,
• wherein the processor performs, based on the UCI resources in the PUSCH, i) a first determination for determining a number of resources for a hybrid automatic repeat request-acknowledgement (HARQ-ACK), and ii) a second determination for determining a number of resources for first channel state information (CSI) after the first determination, and
• wherein, based on that the processor has configured the UE to multiplex UCIs with different priorities in the PUSCH, and the UCIs with the different priorities include first HARQ-ACK information with a first priority and second HARQ-ACK information with a second priority lower than the first priority:
• the processor determines a number of resources for the second HARQ-ACK information based on ii) the second determination by taking the second HARQ-ACK information with the second priority as the first CSI.
