User equipment based positioning
Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a transmitter user equipment (UE) may transmit, to a receiver UE, a first communication that includes a positioning reference signal (PRS) associated with the transmitter UE. The UE may transmit, to the receiver UE, a second communication that includes an information element associated with a boundary of a vehicle associated with the transmitter UE. Numerous other aspects are described.
1. An apparatus for wireless communication at a transmitter user equipment (UE), comprising:
a memory; and
one or more processors, coupled to the memory, configured to:
transmit, to a receiver UE, a first communication that includes a positioning reference signal (PRS) associated with the transmitter UE; and
transmit, to the receiver UE, a second communication that includes an information element associated with a boundary of a vehicle associated with the transmitter UE.
2. The apparatus of claim 1 , wherein the information element indicates a reference position of the vehicle, a location of an antenna of the transmitter UE, a size of the vehicle, an attitude of the vehicle, or a type of the vehicle.
3. The apparatus of claim 2 , wherein the reference position of the vehicle is indicated by one or more coordinates.
4. The apparatus of claim 2 , wherein the location of the antenna of the transmitter UE is indicated relative to the reference position of the vehicle.
5. The apparatus of claim 2 , wherein the size of the vehicle is indicated as one or more dimensions of the vehicle.
6. The apparatus of claim 2 , wherein the attitude of the vehicle is indicated as one or more of a yaw of the vehicle, a pitch of the vehicle, or a roll of the vehicle.
7. The apparatus of claim 2 , wherein the type of the vehicle includes a class of the vehicle.
8. The apparatus of claim 1 , wherein the receiver UE is a roadside unit, and wherein the information element indicates a reference position of the vehicle.
9. The apparatus of claim 1 , wherein the first communication and the second communication are sidelink communications.
10. The apparatus of claim 1 , wherein the first communication and the second communication are radio link communications.
11. An apparatus for wireless communication at a receiver user equipment (UE), comprising:
a memory; and
one or more processors, coupled to the memory, configured to:
receive, from a transmitter UE, a first communication that includes a positioning reference signal (PRS) associated with the transmitter UE; and
receive, from the transmitter UE, a second communication that includes an information element associated with a boundary of a vehicle associated with the transmitter UE.
12. The apparatus of claim 11 , wherein the information element indicates a reference position of the vehicle, a location of an antenna of the transmitter UE, a size of the vehicle, an attitude of the vehicle, or a type of the vehicle.
13. The apparatus of claim 12 , wherein the reference position of the vehicle is indicated by one or more coordinates.
14. The apparatus of claim 12 , wherein the location of the antenna of the transmitter UE is indicated relative to the reference position of the transmitter UE.
15. The apparatus of claim 12 , wherein the size of the vehicle is indicated as one or more dimensions of the vehicle.
16. The apparatus of claim 12 , wherein the attitude of the vehicle is indicated as one or more of a yaw of the vehicle, a pitch of the vehicle, or a roll of the vehicle.
17. The apparatus of claim 12 , wherein the type of the vehicle includes a class of the vehicle.
18. The apparatus of claim 11 , wherein the first communication and the second communication are sidelink communications.
19. The apparatus of claim 11 , wherein the first communication and the second communication are radio link communications.
20. The apparatus of claim 11 , wherein the one or more processors are further configured to determine the boundary of the vehicle based at least in part on the information element.
21. A method of wireless communication performed by a transmitter user equipment (UE), comprising:
transmitting, to a receiver UE, a first communication that includes a positioning reference signal (PRS) associated with the transmitter UE; and
transmitting, to the receiver UE, a second communication that includes an information element associated with a boundary of a vehicle associated with the transmitter UE.
22. The method of claim 21 , wherein the information element indicates a reference position of the vehicle, a location of an antenna of the transmitter UE, a size of the vehicle, an attitude of the vehicle, or a type of the vehicle.
23. The method of claim 22 , wherein the reference position of the vehicle is indicated by one or more coordinates.
24. The method of claim 22 , wherein the location of the antenna of the transmitter UE is indicated relative to the reference position of the vehicle.
25. The method of claim 22 , wherein the size of the vehicle is indicated as one or more dimensions of the vehicle.
26. A method of wireless communication performed by a receiver user equipment (UE), comprising:
receiving, from a transmitter UE, a first communication that includes a positioning reference signal (PRS) associated with the transmitter UE; and
receiving, from the transmitter UE, a second communication that includes an information element associated with a boundary of a vehicle associated with the transmitter UE.
27. The method of claim 26 , wherein the information element indicates a reference position of the vehicle, a location of an antenna of the transmitter UE, a size of the vehicle, an attitude of the vehicle, or a type of the vehicle.
28. The method of claim 27 , wherein the reference position of the vehicle is indicated by one or more coordinates.
29. The method of claim 27 , wherein the location of the antenna of the transmitter UE is indicated relative to the reference position of the transmitter UE.
30. The method of claim 27 , wherein the size of the vehicle is indicated as one or more dimensions of the vehicle.
