Positioning reference signal configurations for co-located transmission reception points

A server configured for supporting positioning of one or more user equipments (UEs) in a wireless network, the server comprising:

• an external interface configured to communicate with entities in the wireless network;
• at least one memory;
• at least one processor communicatively coupled to the external interface, and the at least one memory, wherein the at least one processor is configured to:
• receive from a Transmission Reception Point (TRP), via the external interface, all possible positioning reference signal (PRS) configurations supported by the TRP;
• determine PRS configuration parameters for the TRP, wherein the PRS configuration parameters restrict the PRS resources transmitted by the TRP with respect to PRS resources from the co-located TRPs, wherein the PRS configuration parameters restrict orthogonality of PRS resources transmitted by the TRP with respect to PRS resources from the co-located TRPs to only code division multiplexing, wherein the PRS resources transmitted by the TRP are prohibited from being orthogonal to PRS resources from the co-located TRPs using time division multiplexing or frequency division multiplexing;
• and
• send to the TRP, via the external interface, the PRS configuration parameters.
