Claim 0:
1. A method to enable round-trip time (RTT)-based positioning, comprising:
scanning, by a wireless network interface of user equipment (UE) for beacons within range of the UE;
accessing information from a beacon database maintained by a cloud-based location platform to determine whether RTT capabilities are known for each beacon within range of the UE;
sending, for one or more beacons having unknown RTT capabilities, range requests to attempt to have the one or more beacons measure RTT, and based thereon assigning the one or more beacons a RTT measurement status that indicates the one or more beacons' RTT capabilities; and
uploading at least the RTT measurement status to the cloud-based location platform to update the beacon database,
such that the UE both consumes information regarding RTT capabilities of beacons from the beacon database, and contributes information regarding RTT capabilities of beacons to the beacon database.
