1. A method of wireless positioning performed by a user equipment (UE), comprising:
receiving a set of antenna parameters for a plurality of antenna ports of a transmission-reception point (TRP);
obtaining positioning measurements of a plurality of positioning reference signal (PRS) resources transmitted on the plurality of antenna ports;
reconstructing an underlying physical channel between the TRP and the UE based on the positioning measurements of the plurality of PRS resources; and
determining a downlink angle of arrival (DL-AoD) measurement from the TRP to the UE based on the reconstructed underlying physical channel.
