Abstract: Embodiments of the present disclosure disclose methods and apparatuses for sidelink positioning. A first terminal device transmits capability information of the first terminal device along with a positioning reference signal (PRS), and the capability information indicates a capability to provide the location information of the first terminal device. Then the first terminal device receives a request for the location information of the first terminal device from a second terminal device. Based on receiving the request, the first terminal device transmits the location information along with a subsequent PRS. As such, in embodiments of the present disclosure, the first terminal device may transmit location information according to the request of the second terminal device. Thereby the sidelink positioning performance is improved.

Abstract: Example embodiments of the present disclosure relate to sidelink positioning. In an example method, a terminal device detects a positioning reference signal (PRS) from a second terminal device and location information transmission associated with the PRS in case the location information was transmitted. The terminal device determines that the PRS is transmitted without location information of the second terminal device. The terminal device transmits, to a network device, indication information for indicating the PRS transmitted without the location information of the second terminal device. Sidelink positioning performance can be improved.
