Claim 0:
1. 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 of user equipment (UE) that have observed a beacon, the observations including at least a determined position of each of the plurality of UE, a RTT measurement for each of the plurality of UE by the beacon, a RTT measurement uncertainty, a signal strength associated with the RTT measurement, and a bandwidth associated with the RTT measurement;
using, by the cloud-based location platform, a trilateration algorithm to determine a physical antenna position of the beacon based on at least the determined position of each of the plurality of UE and the RTT measurement of each of the plurality of UE, wherein the determination by the trilateration algorithm is further based on the RTT measurement uncertainty, the signal strength, and the bandwidth for each of the plurality of UE;
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 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.
