Abstract: A method and apparatus are disclosed for a wireless communication device capable of scanning for radar signals while detecting and/or receiving a wireless communication signal. The wireless communication device may include a plurality of local oscillator synthesizers to allow distinct frequency bands to be used for wireless communication signals and radar detection. In some embodiments, the wireless communication device may include a radar detection physical layer (PHY) circuit to detect the presence of radar signals within a received RF signal. The radar detection PHY may have limited functionality suitable primarily for radar signal analysis and not suitable for processing (decoding) communication signals.

Abstract: This disclosure provides systems, methods and apparatuses for performing ranging operations between wireless devices. In some implementations, wireless devices can exchange ranging packets that include packet extensions containing a plurality of long training fields (LTFs). The wireless devices can use the LTFs in the ranging packets to obtain a plurality of round-trip time (RTT) values based on a single exchange of ranging packets. The wireless devices also can use the LTFs to estimate angle of arrival (AoA) and angle of departure (AoD) information of the exchanged ranging packets.
