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.

Abstract: Embodiments of the present disclosure relate to devices, methods, apparatuses and computer readable storage media of the acknowledgement feedback for a positioning in RRC inactive state. The method comprises receiving, at a first device in a radio resource control, RRC, inactive state, information at least indicating a latency requirement for the first device to transmit an acknowledgement feedback for a reception of a message, the message being associated with a positioning of the first device and transmitted from a second device or a fourth device to the first device; and performing the transmission of the acknowledgement feedback for the reception of the message at least based on the information without changing the RRC inactive state. With the solution of the present disclosure, acknowledgement information report can be enabled to guarantee the reliability of positioning assistance data reception. It is benefit for the UE in the aspect of power saving, end-to-end positioning latency reduction and signaling overhead reduction.
