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: Triangular inter-user equipment coordination for new radio sidelink communications is provided. An exemplary apparatus may include at least one processor, and at least one memory. The memory stores instructions that, when executed by the processor, may cause the apparatus at least to receive, from a first device, a request of inter-user equipment coordination. The apparatus may also be caused to determine at least one second device to which to forward the request. The apparatus may also be caused to modify the request and forward the modified request to the at least one second device for the second device to provide a response to the request to the first device. The request may be modified by an indication related to the forwarding to the at least one second device.

Abstract: Systems, methods, apparatuses, and computer program products for sidelink group coordination for group-specific synchronization reference are provided. For example, a method can include determining, by a user equipment, whether a first condition is met for coordination on group synchronization reference for a group of user equipment. The method can also include determining, by the user equipment, whether a second condition is met to act as group synchronization reference user equipment for the group. The method can further include transmitting, by the user equipment, a group synchronization reference signal when determined to act as the group synchronization reference user equipment. The method can additionally include performing, by the user equipment, a reduced synchronization search when determined not to act as the group synchronization reference user equipment.
