Abstract

Disclosed is a method of transmitting a sounding reference signal (SRS) of a user equipment in a wireless communication system, including identifying an SRS transmission count based on an SRS periodicity, a number of SRS symbols, an SRS repetition factor, a system frame number, a number of slots per a frame for a subcarrier spacing, and a slot number within the frame for the subcarrier spacing, and transmitting, to a base station, the SRS based on the SRS transmission count.

Claims (52)

1. A method of transmitting a sounding reference signal (SRS) of a user equipment in a wireless communication system, the method comprising:

identifying an SRS transmission count based on an SRS periodicity, a number of SRS symbols, an SRS repetition factor, a system frame number, a number of slots per a frame for a subcarrier spacing, and a slot number within the frame for the subcarrier spacing; and

transmitting, to a base station, the SRS based on the SRS transmission count.

2. The method of claim 1 ,

wherein the SRS transmission count is identified based on a slot offset with the SRS periodicity, the number of SRS symbols, the SRS repetition factor, the system frame number, the number of slots per the frame for the subcarrier spacing, and the slot number within the frame for the subcarrier spacing.

3. The method of claim 1 ,

wherein frequency hopping for the SRS is performed based on the SRS transmission count.

4. The method of claim 1 ,

wherein the number of SRS symbols is 1, 2, or 4, and

wherein the SRS repetition factor is less than the number of the SRS symbols.

5. The method of claim 1 ,

wherein information for the number of the SRS symbols and information for the SRS repetition factor is received from the base station via higher layer signaling.

6. A user equipment (UE) in a wireless communication system, the UE comprising:

a transceiver; and

at least one processor coupled with the transceiver and configured to:

identify a sounding reference signal (SRS) transmission count based on an SRS periodicity, a number of SRS symbols, an SRS repetition factor, a system frame number, a number of slots per a frame for a subcarrier spacing, and a slot number within the frame for the subcarrier spacing, and

transmit, to a base station, an SRS based on the SRS transmission count.

7. The UE of claim 6 ,

wherein the SRS transmission count is identified based on a slot offset with the SRS periodicity, the number of SRS symbols, the SRS repetition factor, the system frame number, the number of slots per the frame for the subcarrier spacing, and the slot number within the frame for the subcarrier spacing.

8. The UE of claim 6 ,

wherein frequency hopping for the SRS is performed based on the SRS transmission count.

9. The UE of claim 6 ,

wherein the number of SRS symbols is 1, 2, or 4, and

wherein the SRS repetition factor is less than the number of the SRS symbols.

10. The UE of claim 6 ,

wherein information for the number of the SRS symbols and information for the SRS repetition factor is received from the base station via higher layer signaling.

11. A method performed by a base station in a wireless communication system, the method comprising:

receiving, from a user equipment, a sounding reference signal (SRS) based on an SRS transmission count,

wherein the SRS transmission count is based on an SRS periodicity, a number of SRS symbols, an SRS repetition factor, a system frame number, a number of slots per a frame for a subcarrier spacing, and a slot number within the frame for the subcarrier spacing.

12. The method of claim 11 ,

wherein the SRS transmission count is identified based on a slot offset with the SRS periodicity, the number of SRS symbols, the SRS repetition factor, the system frame number, the number of slots per the frame for the subcarrier spacing, and the slot number within the frame for the subcarrier spacing.

13. The method of claim 11 ,

wherein frequency hopping for the SRS is performed based on the SRS transmission count.

14. The method of claim 11 ,

wherein the number of SRS symbols is 1, 2, or 4, and

wherein the SRS repetition factor is less than the number of the SRS symbols.

15. The method of claim 11 ,

wherein information for the number of the SRS symbols and information for the SRS repetition factor is transmitted from the base station via higher layer signaling.

16. A base station in a wireless communication system, the base station comprising:

a transceiver; and

at least one processor coupled with the transceiver and configured to:

receive, from a user equipment, a sounding reference signal (SRS) based on an SRS transmission count,

wherein the SRS transmission count is based on an SRS periodicity, a number of SRS symbols, an SRS repetition factor, a system frame number, a number of slots per a frame for a subcarrier spacing, and a slot number within the frame for the subcarrier spacing.

17. The base station of claim 16 ,

wherein the SRS transmission count is identified based on a slot offset with the SRS periodicity, the number of SRS symbols, the SRS repetition factor, the system frame number, the number of slots per the frame for the subcarrier spacing, and the slot number within the frame for the subcarrier spacing.

18. The base station of claim 16 ,

wherein frequency hopping for the SRS is performed based on the SRS transmission count.

19. The base station of claim 16 ,

wherein the number of SRS symbols is 1, 2, or 4, and

wherein the SRS repetition factor is less than the number of the SRS symbols.

20. The base station of claim 16 ,

wherein information for the number of the SRS symbols and information for the SRS repetition factor is transmitted from the base station via higher layer signaling.
