Abstract

Methods and apparatuses are disclosed for flexible reconfiguration of the sounding reference signal (SRS). In one embodiment, a method implemented in a network node includes signaling a sounding reference signal (SRS) configuration, the SRS configuration including an SRS configuration parameter that indicates whether to use one of a staggered comb and a non-staggered comb for an SRS transmission; and receiving the SRS transmission according to the one of the staggered comb and the non-staggered comb indicated by the SRS configuration parameter. In one embodiment, a method implemented in a WD includes receiving a SRS configuration, the SRS configuration including an SRS configuration parameter that indicates whether to use one of a staggered comb and a non-staggered comb for an SRS transmission; and transmitting the SRS transmission according to the one of the staggered comb and the non-staggered comb indicated by the SRS configuration parameter.

First claim

The invention claimed is:

1. A network node configured to communicate with a wireless device, the network node configured comprising a radio interface and processing circuitry configured to:
signal a sounding reference signal, SRS, configuration, the SRS configuration including an SRS configuration parameter that indicates whether to use one of a staggered comb and a non-staggered comb for an SRS transmission, the SRS configuration parameter indicating a resource element position offset and the resource element position offset being dependent on at least one of a size of the comb and a number of SRS symbols; and
receive the SRS transmission according to the one of the staggered comb and the non-staggered comb indicated by the SRS configuration parameter.

2. The network node of claim 1 , wherein the SRS configuration parameter is signaled via radio resource control, RRC, signaling.

3. The network node of claim 1 , wherein the SRS configuration further includes a usage parameter and the SRS configuration parameter that indicates whether to use one of the staggered comb and the non-staggered comb for the SRS transmission is at least one of different from and independent of the usage parameter.

4. The network node of claim 3 , wherein the usage parameter is positioning.

5. A method implemented in a network node, the method comprising:
signaling a sounding reference signal, SRS, configuration, the SRS configuration including an SRS configuration parameter that indicates whether to use one of a staggered comb and a non-staggered comb for an SRS transmission, the SRS configuration parameter indicating a resource element position offset and the resource element position offset being dependent on at least one of a size of the comb and a number of SRS symbols; and
receiving the SRS transmission according to the one of the staggered comb and the non-staggered comb indicated by the SRS configuration parameter.

6. The method of claim 5 , wherein the SRS configuration parameter is signaled via radio resource control, RRC, signaling.

7. The method of claim 5 , wherein the SRS configuration further includes a usage parameter and the SRS configuration parameter that indicates whether to use one of the staggered comb and the non-staggered comb for the SRS transmission is at least one of different from and independent of the usage parameter.

8. The method of claim 7 , wherein the usage parameter is positioning.

9. A wireless device ( 22 ), WD, configured to communicate with a network node, the WD comprising a radio interface and a processing circuitry configured to:
receive a sounding reference signal, SRS, configuration, the SRS configuration including an SRS configuration parameter that indicates whether to use one of a staggered comb and a non-staggered comb for an SRS transmission, the SRS configuration parameter indicating a resource element position offset and the resource element position offset being dependent on at least one of a size of the comb and a number of SRS symbols; and
transmit the SRS transmission according to the one of the staggered comb and the non-staggered comb indicated by the SRS configuration parameter.

10. The WD of claim 9 , wherein the SRS configuration parameter is received via radio resource control, RRC, signaling.

11. The WD of claim 9 , wherein the SRS configuration further includes a usage parameter and the SRS configuration parameter that indicates whether to use one of the staggered comb and the non-staggered comb for the SRS transmission is at least one of different from and independent of the usage parameter.

12. The WD of claim 11 , wherein the usage parameter is positioning.

13. A method implemented in a wireless device (WD), the method comprising:
receiving a sounding reference signal (SRS) configuration, the SRS configuration including an SRS configuration parameter that indicates whether to use one of a staggered comb and a non-staggered comb for an SRS transmission, the SRS configuration parameter indicating a resource element position offset and the resource element position offset being dependent on at least one of a size of the comb and a number of SRS symbols; and
transmitting the SRS transmission according to the one of the staggered comb and the non-staggered comb indicated by the SRS configuration parameter.

14. The method of claim 13 , wherein the SRS configuration parameter is received via radio resource control, RRC, signaling.

15. The method of claim 13 , wherein the SRS configuration further includes a usage parameter and the SRS configuration parameter that indicates whether to use one of the staggered comb and the non-staggered comb for the SRS transmission is at least one of different from and independent of the usage parameter.

16. The method of claim 15 , wherein the usage parameter is positioning.
