Synchronization and resource allocation for sidelink positioning

An apparatus, comprising:

• a memory;
• and
• at least one processor in communication with the memory and configured to:
• generate instructions to transmit, to a plurality of wireless devices, an anchor selection request for a sidelink positioning procedure for a target user equipment device (UE);
• receive, from one or more wireless devices of the plurality of wireless devices, an anchor selection response that includes information indicative of synchronization-reference characteristics associated with each wireless device of the one or more wireless devices, wherein the synchronization-reference characteristics include at least one of a synchronization source identifier, a relative time difference, or synchronization quality information;
• and
• select, based, at least in part, on the synchronization-reference characteristics included in the anchor selection responses, one or more anchor devices from the one or more wireless devices that satisfy a synchronization-reference criterion.

A device, comprising:

• a memory;
• at least one network interface;
• and
• one or more processors, in communication with the memory and the at least one network interface, configured to cause the device to:
• transmit, to a plurality of wireless devices, an anchor selection request for a sidelink positioning procedure for a target user equipment device (UE);
• receive, from one or more wireless devices of the plurality of wireless devices, an anchor selection response that includes information indicative of synchronization-reference characteristics associated with each wireless device of the one or more wireless devices, wherein the synchronization-reference characteristics include at least one of a synchronization source identifier, a relative time difference, or synchronization quality information;
• and
• select, based, at least in part, on the synchronization-reference characteristics included in the anchor selection responses, one or more anchor devices from the one or more wireless devices that satisfy a synchronization-reference criterion.
