Abstract: In a particular aspect, an apparatus includes first communication circuitry configured to perform first fine timing measurement (FTM) operations with respect to a device to generate first measurement data. The first FTM operation correspond to a first frequency band. The apparatus includes second communication circuitry configured to perform second FTM operations with respect to the device to generate second measurement data. The second FTM operations correspond to a second frequency band that is different than the first frequency band. The apparatus also includes a processor configured to compare the first measurement data and the second measurement data.

Abstract: Certain aspects of the present disclosure generally relate to beamforming training for a sector corresponding to a line of sight (LOS). For example, certain aspects of the present disclosure provide an apparatus for wireless communications. The apparatus generally includes an interface for obtaining a plurality of frames from a wireless node during a sector sweep procedure, and a processing system configured to select a frame of the plurality of frames as corresponding to a line of sight (LOS) between the apparatus and the wireless node based on a relative time of flight (RTOF) of the frame, and perform beamforming using the selected frame.
