Title: FTM PROTOCOL ENHANCEMENTS TO SUPPORT SBS/DBS MODE
Abstract:
This disclosure provides systems, methods and apparatuses for performing ranging operations between a transmitting device and one or more receiving devices using one or more wireless channels. In some implementations, a transmitting device may substantially concurrently exchange, on each of a plurality of wireless channels, a corresponding set of FTM frames and acknowledgement (ACK) frames with a receiving device, and then determine a distance to the receiving device based on the plurality of exchanged sets of FTM and ACK frames. In some other implementations, the transmitting device may substantially concurrently exchange, with each of a plurality of receiving devices, a corresponding set of FTM frames and ACK frames on a corresponding one of a plurality of wireless channels, and then determine a distance to each of the plurality of receiving devices based on the corresponding sets of exchanged FTM and ACK frames.
