Abstract

Disclosed are a method for transmitting/receiving an uplink signal between a base station and a terminal, and a device for supporting the same. More specifically, disclosed are a method for transmitting/receiving a signal between a terminal and a base station for the coexistence of terminals to which different transmission time intervals (TTIs) are applied when the terminals to which the different TTIs are applied send an uplink signal on the same resource, and a device for supporting the same.

Claims

1. A method of operating a User Equipment (UE) in a wireless communication system that includes a base station (BS), the method comprising:

receiving, from the BS, downlink control information (DCI); and

transmitting, to the BS, a Physical Uplink Control Channel (PUCCH) signal according to a PUCCH configuration that is selected from a set of PUCCH configurations based on the DCI,

wherein each PUCCH configuration of the set of PUCCH configurations identifies;

a corresponding number of PUCCH symbols to be used for transmitting the PUCCH, and

a corresponding PUCCH symbol index to be used for transmitting the PUCCH, and

wherein the PUCCH configuration is selected from the set of PUCCH configurations based on a slot index included in the DCI.

2. The method of claim 1, wherein the set of PUCCH configurations is provided via a higher layer of the UE.

3. The method of claim 1, wherein the PUCCH symbol index comprises an index for a starting PUCCH symbol.

4. The method of claim 1, wherein the DCI is UE-specific DCI.

5. A User Equipment (UE) for operating in a wireless communication system that includes a base station (BS), the UE comprising:

a memory;

a transceiver; and

a processor operatively connected to the memory and the transceiver, the processor for;

receiving, from the BS, downlink control information (DCI); and

transmitting, to the BS, a Physical Uplink Control Channel (PUCCH) signal according to a PUCCH configuration that is selected from a set of PUCCH configurations based on the DCI,

wherein each PUCCH configuration of the set of PUCCH configurations identifies;

a corresponding number of PUCCH symbols to be used for transmitting the PUCCH, and

a corresponding PUCCH symbol index to be used for transmitting the PUCCH, and

wherein the PUCCH configuration is selected from the set of PUCCH configurations based on a slot index included in the DCI.

6. The UE of claim 5, wherein the set of PUCCH configurations is provided via a higher layer of the UE.

7. The UE of claim 5, wherein the PUCCH symbol index comprises an index for a starting PUCCH symbol.

8. The UE of claim 5, wherein the DCI is UE-specific DCI.

9. A method of operating a base station (BS) in a wireless communication system that includes a User Equipment (UE), the method comprising:

transmitting, to the UE, downlink control information (DCI); and

receiving, from the UE, a Physical Uplink Control Channel (PUCCH) signal according to a PUCCH configuration that is selected by the UE from a set of PUCCH configurations based on the DCI,

wherein each PUCCH configuration of the set of PUCCH configurations identifies;

a corresponding number of PUCCH symbols to be used by the UE for transmitting the PUCCH, and

a corresponding PUCCH symbol index to be used by the UE for transmitting the PUCCH, and

wherein the PUCCH configuration is selected from the set of PUCCH configurations based on a slot index included in the DCI.

10. The method of claim 9, wherein the set of PUCCH configurations is provided to the UE by the BS.

11. The method of claim 9, wherein the PUCCH symbol index comprises an index for a starting PUCCH symbol.

12. The method of claim 9, wherein the DCI is UE-specific DCI.

13. A base station (BS) for operating in a wireless communication system that includes a User Equipment (UE), the BS comprising:

a memory;

a transceiver; and

a processor operatively connected to the memory and the transceiver, the processor for;

transmitting, to the UE, downlink control information (DCI); and

receiving, from the UE, a Physical Uplink Control Channel (PUCCH) signal according to a PUCCH configuration that is selected by the UE from a set of PUCCH configurations based on the DCI,

wherein each PUCCH configuration of the set of PUCCH configurations identifies;

a corresponding number of PUCCH symbols to be used by the UE for transmitting the PUCCH, and

a corresponding PUCCH symbol index to be used by the UE for transmitting the PUCCH, and

wherein the PUCCH configuration is selected from the set of PUCCH configurations based on a slot index included in the DCI.

14. The BS of claim 13, wherein the set of PUCCH configurations is provided to the UE by the BS.

15. The BS of claim 13, wherein the PUCCH symbol index comprises an index for a starting PUCCH symbol.

16. The BS of claim 13, wherein the DCI is UE-specific DCI.
