AI Technical Summary
Technical Problem
Existing sidelink positioning technologies in V2X communication face challenges when user equipment (UEs) are associated with different public land mobile networks (PLMNs), leading to potential interruptions and inefficiencies in the sidelink positioning procedure.
Method used
A location management apparatus and method that allows anchor radio terminals to detach from their serving radio access nodes, enabling the sidelink positioning procedure to proceed without interference from different location management functions (LMFs).
Benefits of technology
This solution ensures uninterrupted and efficient sidelink positioning by preventing interruptions from different LMFs and allowing anchor UEs to operate in partial coverage mode, even when associated with different PLMNs.

Abstract
There is provided a location management apparatus (LMF#1) comprising at least one processor; at least one memory including computer program code; and at least one radio communication module; the at least one processor, the at least one memory, the at least one computer program code, and the at least one radio communications module cause the location management apparatus (LMF#1) to perform at least: transmitting (318), via a downlink channel, a detachment request (DR#1), indicating that at least one anchor radio terminal (UE#2), which is selected for conducting a sidelink positioning procedure (SLP), and which is served by a different radio access node (gNB#2) than a location management function, LMF, of the location management apparatus (LMF#1) is associated with, shall detach from the different radio access node (gNB#2); receiving (336), via an uplink channel, at least one measurement report (MES#2) associated with the at least one anchor terminal (UE#2); determining (338), based on the at least one measurement report (MES#2), at least one position information (P) indication the position of a target radio terminal (UE#1); and transmitting (340) the at least one position information (P) to a requesting entity (RE).
