Abstract

A terminal according to an embodiment of the present invention can: encode a plurality of UCIs comprising a first UCI and a second UCI; perform resource mapping on the encoded bits of the plurality of UCIs on a single physical uplink channel; and perform uplink transmission on the basis of the resource mapping. Even when the first UCI and the second UCI have different priorities, the terminal can separately encode the first UCI and the second UCI on the basis that the first UCI and the second UCI are configured to be multiplexed on the single physical uplink channel, and perform the resource mapping on the second UCI having the lower priority on the basis of the resource mapping of the first UCI having the higher priority.

First claim

What is claimed is:

1 . A method of transmitting a signal by a user equipment (UE) in a wireless communication system, the method 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 UE 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 UE 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 UE 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.

2 . The method of claim 1 , wherein the UE determines a number of resources for the first HARQ-ACK information based on i) the first determination, after determining resources for a demodulation reference signal (DMRS).

3 . The method of claim 1 , wherein the UE determines the number of resources for the second HARQ-ACK information based on ii) the second determination, after determining the number of resources for the first HARQ-ACK information based on i) the first determination.

4 . The method of claim 1 , wherein CSI with the first priority is not included in the PUSCH.

5 . The method of claim 1 , wherein the first priority has a priority index 1 and the second priority has a priority index 0.

6 . The method of claim 1 , further comprising:
receiving, through higher layer signaling, configuration information for the UE to multiplex the UCIs with the different priorities.

7 . A non-transitory computer-readable medium storing instruction for performing the method of claim 1 .

8 . 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.

9 . The device of claim 8 , 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.

10 . The device of claim 8 , 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.

11 . 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.

12 . The method of claim 11 , wherein the BS determines a number of resources for the first HARQ-ACK information based on i) the first determination, after determining resources for a demodulation reference signal (DMRS).

13 . The method of claim 11 , the BS determines the number of resources for the second HARQ-ACK information based on ii) the second determination, after determining the number of resources for the first HARQ-ACK information based on i) the first determination.

14 . The method of claim 11 , wherein CSI with the first priority is not included in the PUSCH.

15 . The method of claim 11 , wherein the first priority has a priority index 1 and the second priority has a priority index 0.

16 . The method of claim 11 , further comprising:
transmitting, through higher layer signaling, configuration information for the UE to multiplex the UCIs with the different priorities.

17 . 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.
