Abstract: Round trip time (RTT) measurements may be obtained from downlink (DL) trigger frame and uplink (UL) Multiple-Input Multiple-Output (MIMO) frame transactions, which can replace and/or complement separate RTT measurements. By implementing such techniques, wireless systems can make access to RTT measurements, and consequently, location determination of access points (APs) within the system, more easily accessible to navigation and/or other applications benefitting from such measurements and determinations.
