sending, to a transmitting UE (Tx UE) and a receiving UE (Rx UE), a request for sidelink (SL) positioning reference signal (PRS) capabilities data;
receiving, from each of the Tx UE and the Rx UE, respective SL PRS capabilities data;
configuring a SL positioning reference signal (PRS) that is based on the SL PRS capabilities data for each of the Tx UE and the Rx UE;
sending data specifying a selected SL PRS configuration to the Tx UE;
receiving an acknowledgement signal from the Tx UE indicating a Tx UE SL PRS configuration that is based on the selected SL PRS configuration; and
providing, to the Rx UE, the Tx UE SL PRS configuration.
