Method and apparatus 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:
• multiplexing uplink control information (UCI) in a physical uplink shared channel (PUSCH);
• and
• transmitting the PUSCH,
• wherein the device is configured to multiplex UCIs with different priorities, and
• wherein, based on that the UCI multiplexed in the PUSCH includes 2-part channel state information (CSI) with a larger priority index between a first priority index and a second priority index, the processor drops hybrid automatic repeat request-acknowledgement (HARQ-ACK) information with a smaller priority index between the first priority index and the second priority index, and multiplexes a first part of the 2-part CSI and a second part of the 2-part CSI in the PUSCH.

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

• receiving, from a user equipment (UE), a physical uplink shared channel (PUSCH);
• and
• obtaining uplink control information (UCI) multiplexed in the received PUSCH,
• wherein the BS configures the UE to multiplex UCIs with different priorities, and
• wherein, based on that the UCI multiplexed in the PUSCH includes 2-part channel state information (CSI) with a larger priority index between a first priority index and a second priority index, hybrid automatic repeat request-acknowledgement (HARQ-ACK) information with a smaller priority index between the first priority index and the second priority index is dropped, and a first part of the 2-part CSI and a second part of the 2-part CSI are multiplexed in the PUSCH.

A base station (BS) for wireless communication, the BS comprising:

• a transceiver;
• and
• a processor configured to receive, through transceiver from a user equipment (UE), a physical uplink shared channel (PUSCH) and to obtain uplink control information (UCI) multiplexed in the received PUSCH,
• wherein the processor configures the UE to multiplex UCIs with different priorities, and
• wherein, based on that the UCI multiplexed in the PUSCH includes 2-part channel state information (CSI) with a larger priority index between a first priority index and a second priority index, hybrid automatic repeat request-acknowledgement (HARQ-ACK) information with a smaller priority index between the first priority index and the second priority index is dropped, and a first part of the 2-part CSI and a second part of the 2-part CSI are multiplexed in the PUSCH.
