Method and apparatus for transmitting and receiving signal in wireless communication system
A user equipment (UE) operation related to at least one of embodiments of the disclosure may include multiplexing a plurality of UCIs on a single physical uplink shared channel (PUSCH), and transmitting the single PUSCH in which the plurality of UCIs are multiplexed. Based on that the UE is configured to multiplex UCIs having different priorities on the same PUSCH, that a priority of a first UCI included in the plurality of UCIs is Priority-H higher than Priority-L, and that the first UCI with the Priority-H includes 2-part channel state information (CSI), the UE may drop all hybrid automatic repeat request-acknowledgement (HARQ-ACK) information of a second UCI with the Priority-L lower than the Priority-H, and map a first part of the CSI and a second part of the CSI onto the single PUSCH.
1. A method of transmitting a signal by a user equipment (UE) in a wireless communication system, the method comprising:
multiplexing uplink control information (UCI) in a physical uplink shared channel (PUSCH); and
transmitting the PUSCH,
wherein the UE 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) including a first part and a second part with a larger priority index between a first priority index and a second priority index, the UE 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 the first part of the 2-part CSI and the second part of the 2-part CSI in the PUSCH, and
wherein the 2-part CSI including the first part and the second part is related to an aperiodic CSI report.
2. The method according to claim 1 , wherein the multiplexing of the UCI is performed by taking potential HARQ-ACK information with the larger priority index as UCI type 1.
3. The method according to claim 2 , wherein the multiplexing of the UCI is performed by taking the first part of the 2-part CSI and the second part of the 2-part CSI as UCI type 2 and UCI type 3, respectively.
4. The method according to claim 1 , wherein resource element (RE) reservation for potential HARQ-ACK information with the larger priority index is performed in the PUSCH.
5. The method according to claim 4 , wherein the RE reservation for the potential HARQ-ACK information with the larger priority index is performed even in a case where the UCI multiplexed in the PUSCH does not include any HARQ-ACK information with the larger priority index.
6. The method according to claim 4 , wherein the first part of the 2-part CSI is not mapped to REs reserved for the potential the HARQ-ACK information with the larger priority index, and
wherein, after mapping the first part of the 2-part CSI, the second part of the 2-part CSI and data are mapped to remaining REs including the REs reserved for the potential the HARQ-ACK information with the larger priority index.
7. The method according to claim 6 , wherein based on a presence of 1-bit or 2-bit of actual HARQ-ACK with the larger priority index, the UE punctures the second part of the 2-part CSI and the data from the reserved REs and maps the 1-bit or 2-bit of the actual HARQ-ACK with the larger priority index.
8. The method according to claim 1 , wherein the PUSCH has the larger priority index.
9. The method according to claim 1 , wherein the smaller priority index is an integer 0, and the larger priority index is an integer 1.
10. A non-transitory computer-readable storing instructions for performing the method of claim 1 .
11. A device for wireless communication, the device comprising:

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) including a first part and a second part 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 the first part of the 2-part CSI and the second part of the 2-part CSI in the PUSCH, and
wherein the 2-part CSI including the first part and the second part is related to an aperiodic CSI report.
12. The device of claim 11 , further comprising:
a transceiver configured to transmit or receive a wireless signal under control of the processor,
wherein the device is a user equipment (UE) configured to operate in a wireless communication system.
13. The device of claim 11 , wherein the device is an application specific integrated circuit (ASIC) or a digital signal processing device configured control a user equipment (UE) to operate in a wireless communication system.
14. 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) including a first part and a second part 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 the first part of the 2-part CSI and the second part of the 2-part CSI are multiplexed in the PUSCH, and
