Claim 11:
12. A method to enable round-trip time (RTT)-based positioning, comprising:
receiving, by a cloud-based location platform that maintains a beacon database, observations from a plurality user equipment (UE) that have observed a beacon, the observations including a RTT measurement for each of the plurality of UE by the beacon;
determining, by the cloud-based location platform, a physical antenna position of the beacon using a weighted least square (WLS) multilateration algorithm that calculates the physical antenna position based on the determined position and the RTT measurement of each of the plurality of UE weighted by a position confidence of the determined position;
updating the beacon database to include the determined physical antenna position of the beacon; and
providing, by the cloud-based location platform, the physical antenna position of the beacon to one or more UE of the plurality of UE,
such that the one or more UE both contribute information used to determine the physical antenna position of the beacon to build the beacon database and consume the physical antenna position of the beacon from the beacon database.
