Abstract

Disclosed are techniques for wireless communication. In an aspect, a first user equipment (UE) receives, from a network entity, a capability enquiry message for a sidelink positioning procedure, the capability enquiry message including at least a request for an indication of whether the first UE has the capability to provide a location of the first UE for the sidelink positioning procedure, and transmits, to the network node, a capability information message indicating one or more capabilities of the first UE to participate in the sidelink positioning procedure, the one or more capabilities of the first UE including at least the indication of whether the first UE has the capability to provide the location of the first UE for the sidelink positioning procedure.

Claims (67)

1. A method of wireless communication performed by a first user equipment (UE), comprising:

receiving, from a second UE, a discovery message for a sidelink positioning procedure, the discovery message including at least a request for an indication that the first UE has the capability to provide a location of the first UE for the sidelink positioning procedure; and

transmitting, to the second UE, a capability information message indicating one or more capabilities of the first UE to participate in the sidelink positioning procedure, the one or more capabilities of the first UE including at least the indication that the first UE has the capability to provide the location of the first UE for the sidelink positioning procedure.

2. The method of claim 1 , wherein the one or more capabilities of the first UE include an indication that the first UE has the capability to provide position calculation for the sidelink positioning procedure based on received location measurement information.

3. The method of claim 1 , further comprising:

receiving, from the second UE a second request for a location of the first UE; and

transmitting, to the second UE, the location of the first UE.

4. The method of claim 1 , wherein the one or more capabilities of the first UE include location coordinates of the first UE.

5. The method of claim 1 , wherein:

the discovery message is a first radio resource control (RRC) message, a first medium access control control element (MAC-CE), first sidelink control information (SCI), or a first Long-Term Evolution (LTE) positioning protocol (LPP) message, and

the capability information message is a second RRC message, a second MAC-CE, second SCI, or a second LPP message.

6. The method of claim 1 , wherein the indication that the first UE has the capability to provide the location of the first UE for the sidelink positioning procedure is a Boolean value.

7. A method of wireless communication performed by a second user equipment (UE), comprising:

transmitting, to a first UE, a discovery message for a sidelink positioning procedure, the discovery message including at least a request for an indication that the first UE has the capability to provide a location of the first UE for the sidelink positioning procedure; and

receiving, from the first UE, a capability information message indicating one or more capabilities of the first UE to participate in the sidelink positioning procedure, the one or more capabilities of the first UE including at least the indication that the first UE has the capability to provide the location of the first UE for the sidelink positioning procedure.

8. The method of claim 7 , further comprising:

transmitting, to the first UE, a second request for a location of the first UE; and

receiving, from the first UE, the location of the first UE.

9. The method of claim 7 , wherein the one or more capabilities of the first UE include location coordinates of the first UE.

10. The method of claim 7 , wherein the one or more capabilities of the first UE include an indication that the first UE has the capability to provide position calculation for the sidelink positioning procedure based on received location measurement information.

11. The method of claim 7 , wherein:

the capability information message is a second RRC message, a second MAC-CE, second SCI, or a second LPP message.

12. The method of claim 7 , wherein the indication that the first UE has the capability to provide the location of the first UE for the sidelink positioning procedure is a Boolean value.

13. An apparatus for wireless communication, comprising:

one or more memories; and

one or more processors coupled to the one or more memories, the one or more processors configured to cause a first user equipment (UE) to:

receive, from a second UE, a discovery message for a sidelink positioning procedure, the discovery message including at least a request for an indication that the first UE has the capability to provide a location of the first UE for the sidelink positioning procedure; and

transmit, to the second UE, a capability information message indicating one or more capabilities of the first UE to participate in the sidelink positioning procedure, the one or more capabilities of the first UE including at least the indication that the first UE has the capability to provide the location of the first UE for the sidelink positioning procedure.

14. The apparatus of claim 13 , wherein:

the capability information message is a second RRC message, a second MAC-CE, second SCI, or a second LPP message.

15. The apparatus of claim 13 , wherein the indication that the first UE has the capability to provide the location of the first UE for the sidelink positioning procedure is a Boolean value.

16. The apparatus of claim 13 , wherein the one or more capabilities of the first UE include an indication that the first UE has the capability to provide position calculation for the sidelink positioning procedure based on received location measurement information.

17. The apparatus of claim 16 , wherein the one or more processors are further configured to cause the first UE to:

determine a location of the second UE based, at least in part, on a location of the first UE and measurements of positioning reference signals received from the second UE.

18. The apparatus of claim 16 , wherein the indication that the first UE has the capability to provide position calculation for the sidelink positioning procedure is a Boolean value.

19. The apparatus of claim 13 , wherein the one or more processors are further configured to cause the first UE to:

receive, from the second UE, a second request for a location of the first UE; and

transmit, to the second UE, the location of the first UE.

20. The apparatus of claim 13 , wherein the one or more capabilities of the first UE include location coordinates of the first UE.

21. The apparatus of claim 13 , wherein the second UE is a target UE to be positioned.

22. The apparatus of claim 21 , wherein:

the discovery message comprises a “UECapabilityEnquirySidelink” information element (IE), and

the capability information message comprises a “UECapabilityInformationSidelink” IE.

23. The apparatus of claim 22 , wherein the indication that the first UE has the capability to provide the location of the first UE for the sidelink positioning procedure comprises a “PositionAnchorCapabilityStatus” field in the “UECapabilityEnquirySidelink” IE, the “UECapabilityInformationSidelink” IE, or both.
