1. A method performed by a server for supporting positioning of one or more user equipments (UEs) in a wireless network, the method comprising:
receiving from a Transmission Reception Point (TRP) all possible positioning reference signal (PRS) configurations supported by the TRP;
determining 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
sending to the TRP the PRS configuration parameters.
