Abstract
A wireless communication device can determine its position in accordance with a hybrid positioning mechanism to minimize bandwidth and power consumption at the wireless communication device. The wireless communication device can detect one or more request messages and one or more corresponding response messages exchanged between a master access point and one or more target access points, and can accordingly determine TDOA information associated with the one or more target access points. The wireless communication device can receive, from the master access point, RTT measurement information determined by the master access point based, at least in part, on the one or more request messages and the one or more corresponding response messages exchanged between the master access point and the one or more target access points. The wireless communication device can calculate its position information based, at least in part, on the TDOA information and the RTT measurement information.
