Positioning reference signal configuration for measurement sharing via sidelink

A user equipment (UE), comprising:

• a memory;
• a communication interface;
• and
• at least one processor communicatively coupled to the memory and the communication interface, the at least one processor configured to:
• receive, via the communication interface, from a network node, at least one positioning reference signal (PRS) configuration that defines or indicates a plurality of PRS resources having unique identifiers, the plurality of PRS resources comprising a first set of one or more PRS resources, wherein each of the one or more PRS resources in the first set is mapped to an associated identifier used by all UEs served by a location server to identify an associated PRS resource, the plurality of PRS resources further comprising a second set of one or more PRS resources, wherein each of the one or more PRS resources in the second set is mapped to an associated identifier that is specific to a UE and that is not used by all UEs served by the location server to identify the associated PRS resource;
• and
• perform a positioning operation according to the at least one PRS configuration.

A network node, comprising:

• a memory;
• a communication interface;
• and
• at least one processor communicatively coupled to the memory and the communication interface, the at least one processor configured to:
• determine a plurality of PRS resources having unique identifiers, the plurality of PRS resources comprising a first set of one or more PRS resources, wherein each of the one or more PRS resources in the first set is mapped to an associated identifier used by all UEs served by a location server to identify an associated PRS resource, the plurality of PRS resources further comprising a second set of one or more PRS resources, wherein each of the one or more PRS resources in the second set is mapped to an associated identifier that is specific to a UE and that is not used by all UEs served by the location server to identify the associated PRS resource;
• and
• cause the communication interface to send, to the UE, at least one PRS configuration that defines or indicates the first set and the second set.
