Abstract:
Apparatuses and methods are disclosed for performing ranging operations between a first device and a second device. The first device may receive, from the second device, a fine timing measurement (FTM) request frame including a request to estimate angle information for a number of frames exchanged with the second device and indicating a level of accuracy for the estimated angle information. The first device may transmit a first FTM frame to the second device, may receive an acknowledgement (ACK) frame from the second device, and may transmit, to the second device, a second FTM frame including angle information of the first FTM frame and timing information of one or more of the exchanged frames.
