Abstract

Claims (50)

1. A method of positioning performed by a first UE (user equipment) that is a bandwidth-limited UE, the method comprising:

determining, by the first UE, that at least one second UE is disposed proximate to the first UE, wherein the at least one second UE is capable of using more bandwidth than the first UE for processing received signals;

obtaining an identification for the at least one second UE from a transmission-reception point (TRP);

receiving, based on determining that the at least one second UE is disposed proximate to the first UE, a first timing measurement signal from the at least one second UE, wherein the first timing measurement signal is received via a sidelink connection;

transmitting, from the first UE, a second timing measurement signal to the at least one second UE, wherein the second timing measurement signal is transmitted via the sidelink connection.

2. The method of claim 1 further comprising:

establishing a sidelink connection to the at least one second UE, wherein the first timing measurement signal is received via the sidelink connection.

3. The method of claim 1 further comprising:

providing a measurement request message to the at least one second UE prior to receiving the first timing measurement signal; and

providing, from the first UE, based on determining that the at least one second UE is disposed proximate to the first UE, a measurement request message to the at least one second UE to transmit a first timing measurement signal;

wherein receiving the first timing measurement signal is based on providing the measurement request message.

4. The method of claim 1 further comprising receiving location information from the at least one second UE.

5. The method of claim 1 wherein the first timing measurement signal and the second timing measurement signal utilize a channel state information reference signal.

6. The method of claim 5 wherein the channel state information reference signal is within a physical sidelink control channel.

7. A first UE (user equipment) that is a bandwidth-limited UE, comprising:

a memory;

a transceiver;

at least one processor operably coupled to the memory and the transceiver and configured to:

determine that at least one second UE is disposed proximate to the first UE;

obtain an identification for the at least one second UE from a transmission-reception point (TRP);

receive, via the transceiver based on determining that the at least one second UE is disposed proximate to the first UE, a first timing measurement signal from the at least one second UE, wherein the first timing measurement signal is received via a sidelink connection, and wherein the at least one second UE is capable of using more bandwidth than the first UE for processing received signals; and

transmit, via the transceiver, a second timing measurement signal to the at least one second UE, wherein the second timing measurement signal is transmitted via the sidelink connection.

8. The first UE of claim 7 wherein the at least one processor is further configured to establish a sidelink connection to the at least one second UE, and wherein the at least one processor is configured to receive the first timing measurement signal via the sidelink connection.

9. The first UE of claim 8 wherein the at least one processor is configured to transmit the second timing measurement signal via the sidelink connection.

10. The first UE of claim 7 wherein the at least one processor is further configured to provide a measurement request message to the at least one second UE prior to receiving the first timing measurement signal.

11. The first UE of claim 7 wherein the at least one processor is further configured to receive location information from the at least one second UE.

12. The first UE of claim 7 wherein the first timing measurement signal and the second timing measurement signal utilize a channel state information reference signal.

13. The first UE of claim 12 wherein the channel state information reference signal is within a physical sidelink control channel.

14. An apparatus for positioning a first UE (user equipment) that is a bandwidth-limited UE, comprising:

means for determining that at least one second UE is disposed proximate to the first UE;

means for obtaining an identification for the at least one second UE from a transmission-reception point (TRP);

means for receiving, based on determining that the at least one second UE is disposed proximate to the first UE, a first timing measurement signal from the at least one second UE, wherein the first timing measurement signal is received via a sidelink connection, wherein the at least one second UE is capable of using more bandwidth than the first UE for processing received signals; and

means for transmitting a second timing measurement signal to the at least one second UE, wherein the second timing measurement signal is transmitted via the sidelink connection.

15. The apparatus of claim 14 further comprising:

means for establishing a sidelink connection to the at least one second UE, wherein the means for receiving the first timing measurement signal are for receiving the first timing measurement signal via the sidelink connection.

16. The apparatus of claim 14 further comprising means for providing a measurement request message to the at least one second UE prior to receiving the first timing measurement signal.

17. The apparatus of claim 14 further comprising means for receiving location information from the at least one second UE.

18. The apparatus of claim 14 wherein the first timing measurement signal and the second timing measurement signal utilize a channel state information reference signal.

19. The apparatus of claim 18 wherein the channel state information reference signal is within a physical sidelink control channel.

20. A non-transitory computer-readable storage medium comprising computer-readable instructions configured to cause one or more processor to determine a position of a first UE (user equipment) that is a bandwidth-limited UE, comprising:

code for determining that at least one second UE is disposed proximate to the first UE;

code for obtaining an identification for the at least one second UE from a transmission-reception point (TRP);

code for receiving, based on determining that the at least one second UE is disposed proximate to the first UE, a first timing measurement signal from at least one second UE, wherein the first timing measurement signal is received via a sidelink connection, wherein the at least one second UE is capable of using more bandwidth than the first UE for processing received signals; and

code for transmitting a second timing measurement signal to the at least one second UE, wherein the second timing measurement signal is transmitted via the sidelink connection.

21. The non-transitory computer-readable storage medium of claim 20 further comprising:

code for establishing a sidelink connection to the at least one second UE, wherein the code for receiving the first timing measurement signal comprises code for receiving the first timing measurement signal via the sidelink connection.

22. The non-transitory computer-readable storage medium of claim 20 further comprising code for providing a measurement request message to the at least one second UE prior to receiving the first timing measurement signal.

23. The non-transitory computer-readable storage medium of claim 20 further comprising code for receiving location information from the at least one second UE.

24. The non-transitory computer-readable storage medium of claim 20 wherein the first timing measurement signal and the second timing measurement signal utilize a channel state information reference signal.

25. The non-transitory computer-readable storage medium of claim 24 wherein the channel state information reference signal is within a physical sidelink control channel.
