The base station informs the UE1, e.g., by broadcast or dedicated means, of the resource pool it uses to send positioning assistance information over the Sidelink interface.

The UE1 selects a specific resource for the positioning assistance information according to the allocated resource pool; the received UE2 monitors the positioning assistance information sent on the Sidelink interface in the resource pool; or the UE1 determines the resource corresponding to the transmission control information (for example, the Sidelink SI0 or the control channel 1) according to the allocated resource pool and notifies the resource to the surrounding UEs; meanwhile, the UE1 is shown in the control information (for example, the Sidelink SI0 or the control channel 1 notifies the corresponding scheduling information in the specific positioning assistance message, the specific content is the same as 2); the receiving UE2 determines and receives resources corresponding to control information (e.g., the Sidelink SI0 or the control channel 1) according to the information transmitted by the UE1, and then determines resources corresponding to specific positioning assistance information according to the content of the obtained control information (e.g., the Sidelink SI0 or the control channel 1).

4) UE1 determines the resource corresponding to the specific Sidelink sending positioning assistance information (without base station assistance)

The UE1 sends a resource pool for sending positioning assistance information on the Sidelink interface at a predefined location; the received UE2 monitors the positioning assistance information sent on the Sidelink interface in the resource pool; or, the UE1 sends a resource corresponding to the control information (for example, the above-mentioned Sidelink SI0 or control channel 1) at a predefined location, and at the same time, the UE1 notifies, in the control information, the specific scheduling information for sending the positioning assistance message on the Sidelink, which is shown in the following description 2); the received UE2 first obtains the control information (such as the Sidelink SI0 or the control channel 1) according to the predefined location, and then determines the resource corresponding to the positioning assistance information sent on the specific Sidelink interface according to the content of the obtained control information (such as the Sidelink SI0 or the control channel 1).
