More Information
Summary:Fine Time Measurement (FTM) improvement and, specifically, trigger based FTM improvements via efficiently grouping initiators may be provided. A plurality of probe requests transmitted by a plurality of initiators is received. For each probe request, a Received Signal Strength Indication (RSSI) and Channel State Information (CSI) is determined, and a distance between an initiator and an associated responder associated with the probe request is determined based on the RSSI and the CSI. Line of Sight (LOS) or Non Line of Sight (NLOS) relationships between the plurality of initiators and one or more responders is determined based on the CSI. One or more groups of initiators is determined from the plurality of initiators based on the LOS or NLOS relationships and the distances determined for each probe request, wherein the responders and the initiators perform FTM based on the one or more groups of initiators.
