Abstract

An operating method of a terminal configured to perform vehicle-to-everything (V2X) communication in a wireless communication system, including signaling a maximum physical sidelink feedback channel (PSFCH) receiving capability to a base station; and receiving a wireless signal transmitted from the base station based on the maximum PSFCH receiving capability, wherein the maximum PSFCH receiving capability is a maximum number of PSFCHs receivable during one time transmission interval (TTI).

First claim

What is claimed is:

1. An operating method of a terminal configured to perform vehicle-to-everything (V2X) communication in a wireless communication system, the operating method comprising:
signaling a physical sidelink feedback channel (PSFCH) capability to a base station, wherein the PSFCH capability is a maximum number of PSFCHs which are processable during a time transmission interval (TTI),
wherein the TTI comprises a slot.

2. The operating method of claim 1 , wherein the PSFCH capability comprises a maximum PSFCH receiving capability to the base station, and
wherein the maximum number of the PSFCHs which are processable during the TTI comprises a maximum number of PSFCHs which are receivable during the TTI.

3. The operating method of claim 2 , wherein the maximum number of the PSFCHs which are receivable during the TTI is one of 10, 20, 30, 40, 50, 100, 200, 300, and 410.

4. The operating method of claim 2 , wherein the maximum PSFCH receiving capability comprises a number of PSFCHs which are received in at least one of a groupcast and a unicast.

5. The operating method of claim 1 , wherein the PSFCH capability comprises a maximum PSFCH transmission capability to the base station, and
wherein the maximum number of the PSFCHs which are processable during the TTI comprises a maximum number of PSFCHs which are transmissible during the TTI.

6. The operating method of claim 5 , wherein the maximum number of the PSFCHs which are transmissible during the TTI is one of 1, 2, 3, 4, 5, 10, 20, 30, and 68.

7. The operating method of claim 5 , wherein the maximum PSFCH transmission capability comprises a number of PSFCHs which are transmitted in at least one of a groupcast and a unicast.

8. A terminal configured to perform vehicle-to-everything (V2X) communication, the terminal comprising:
a transceiver configured to transmit and receive one or more wireless signals; and
a processor configured to control the transceiver to transmit signaling for a physical sidelink feedback channel (PSFCH) capability to a base station,
wherein the PSFCH capability is a maximum number of PSFCHs which are receivable during a time transmission interval (TTI).

9. The terminal of claim 8 , wherein the PSFCH capability comprises a maximum PSFCH receiving capability.

10. The terminal of claim 9 , wherein the maximum PSFCH receiving capability is one of 10, 20, 30, 40, 50, 100, 200, 300, and 410.

11. The terminal of claim 9 , wherein the maximum PSFCH receiving capability comprises a number of PSFCHs which are received in at least one of a groupcast and a unicast.

12. The terminal of claim 8 , wherein the PSFCH capability comprises a maximum PSFCH transmission capability to the base station, and
wherein the maximum PSFCH transmission capability comprises a maximum number of PSFCHs which are transmissible during a TTI.

13. The terminal of claim 12 , wherein the maximum PSFCH transmission capability is one of 1, 2, 3, 4, 5, 10, 20, 30, and 68.

14. The terminal of claim 12 , wherein the maximum PSFCH transmission capability comprises a number of PSFCHs which are transmitted in at least one of a groupcast and a unicast.

15. An operating method to perform vehicle-to-everything (V2X) communication in a wireless communication system, the operating method comprising:
signaling a physical sidelink feedback channel (PSFCH) transceiving capability to a base station, wherein the PSFCH transceiving capability is a maximum number of PSFCHs which are transceivable during a time transmission interval (TTI).

16. The operating method of claim 15 , wherein the maximum number of the PSFCHs which are transceivable during the TTI comprises a maximum number of PSFCHs which are receivable during the TTI, and
wherein the maximum number of the PSFCHs which are receivable during the TTI is one of 10, 20, 30, 40, 50, 100, 200, 300, and 410.

17. The operating method of claim 16 , wherein the maximum number of the PSFCHs which are receivable during the TTI is 50.

18. The operating method of claim 15 , wherein the maximum number of the PSFCHs which are transceivable during the TTI comprises a maximum number of PSFCHs which are transmissible during the TTI, and
wherein the maximum number of the PSFCHs which are transmissible during a TTI is one of 1, 2, 3, 4, 5, 10, 20, 30, and 68.

19. The operating method of claim 18 , wherein the maximum number of the PSFCHs which are transmissible during the TTI is 4.
