Sidelink positioning and WLAN-based positioning

1. A method of operating a first user equipment (UE), comprising:

determining a timing for transmission of a first sidelink positioning reference signal (SL-PRS) associated with a positioning procedure for a second UE;

determining a bandwidth for transmission of the first SL-PRS based at least in part on a bandwidth associated with a downlink PRS (DL-PRS) from a wireless-capable network component to the second UE; and

transmitting, to the second UE, the first SL-PRS in accordance with the timing and the bandwidth of the first SL-PRS.

2. The method of claim 1 , wherein the timing for transmission of the first SL-PRS is received from a network component.

3. The method of claim 1 , wherein the timing for transmission of the first SL-PRS is determined based upon a SL-based timing synchronization procedure between the first UE and the second UE.

4. The method of claim 1 ,

wherein the bandwidth of the first SL-PRS is equal to the bandwidth associated with the DL-PRS, or

wherein the bandwidth of the first SL-PRS is set to a maximum supported bandwidth of the first UE, or

a combination thereof.

5. The method of claim 1 , further comprising:

receiving a resource configuration associated with the first SL-PRS from a network component.

6. The method of claim 1 , further comprising:

receiving, from the second UE, an uplink positioning reference signal (UL-PRS); and

transmitting a measurement report based on the first SL-PRS and the UL-PRS to a position estimation entity for position estimation of the second UE.

7. The method of claim 1 , further comprising:

receiving, from the second UE, a second SL-PRS; and

transmitting a measurement report based on the first SL-PRS and the second SL-PRS to a position estimation entity for position estimation of the second UE.

8. The method of claim 1 , wherein a UE status of the first UE is indicated to the second UE in association with the first SL-PRS.

9. The method of claim 1 , wherein the first SL-PRS is configured to mimic the DL-PRS from the wireless-capable network component without a UE status of the first UE being indicated to the second UE in association with the first SL-PRS.

10. A method of operating a second user equipment (UE), comprising:

receiving, from at least one wireless-capable network component, at least one downlink positioning reference signal (DL-PRS) associated with a positioning procedure of the second UE; and

receiving, from a first UE, a first sidelink positioning reference signal (SL-PRS) associated with the positioning procedure of the second UE over a bandwidth that is based at least in part on a bandwidth associated with the at least one DL-PRS from the at least one wireless-capable network component.

11. The method of claim 10 , wherein a timing for transmission of the first SL-PRS is determined based upon a SL-based timing synchronization procedure between the first UE and the second UE.

12. The method of claim 10 ,

wherein the bandwidth of the first SL-PRS is equal to the bandwidth associated with the at least one DL-PRS, or

wherein the bandwidth of the first SL-PRS is set to a maximum supported bandwidth of the first UE, or

a combination thereof.

13. The method of claim 10 , further comprising:

receiving a resource configuration associated with the first SL-PRS from a network component.

14. The method of claim 10 , further comprising:

transmitting, to at least the first UE, an uplink positioning reference signal (UL-PRS); and

transmitting a measurement report based on the first SL-PRS and the UL-PRS to a position estimation entity for position estimation of the second UE.

15. The method of claim 10 , further comprising:

transmitting, to the first UE, a second SL-PRS; and

transmitting a measurement report based on the first SL-PRS and the second SL-PRS to a position estimation entity for position estimation of the second UE.

16. The method of claim 10 , wherein a UE status of the first UE is indicated to the second UE in association with the first SL-PRS.

17. The method of claim 10 , wherein the first SL-PRS is configured to mimic the at least one DL-PRS from the at least one wireless-capable network component base station without a UE status of the first UE being indicated to the second UE in association with the first SL-PRS.

18. A method of operating a network component, comprising:

coordinating transmission of at least one downlink positioning reference signal (DL-PRS) from at least one wireless-capable network component in association with a positioning procedure of a second UE; and

coordinating transmission of a first sidelink positioning reference signal (SL-PRS) from a the first UE in association with the positioning procedure of the second UE over a bandwidth that is based at least in part on a bandwidth associated with the at least one DL-PRS from the at least one wireless-capable network component.

19. The method of claim 18 , wherein the coordination of the first SL-PRS transmission comprises transmitting a timing for transmission of the first SL-PRS to the first UE.

20. The method of claim 18 ,

wherein the bandwidth of the first SL-PRS is equal to the bandwidth associated with the DL-PRS, or

wherein the bandwidth of the first SL-PRS is set to a maximum supported bandwidth of the first UE, or

a combination thereof.

21. The method of claim 18 , wherein the coordination of the first SL-PRS transmission comprises transmitting a resource configuration associated with the first SL-PRS to the first UE, the second UE, or a combination thereof.

22. The method of claim 18 , further comprising:

receiving, from the first UE, a first measurement report based on the first SL-PRS, or

receiving, from the second UE, a second measurement report based on the at least one DL-PRS and the first SL-PRS, or

a combination thereof.
