Abstract:
Embodiments of the present invention are drawn to systems, apparatus and methods that perform wireless ranging procedures using EHT frames supporting large bandwidth transmission. Moreover, ranging specifications are expanded for the EHT frame format in order to support BW320 ranging with improved performance and accuracy. Embodiments of the present invention support high-bandwidth BW320 and BW240 wireless ranging using a EHT frame format and support 802.11az ranging using a high efficiency (HE) for 802.11be devices. Long training field (LTF) repetition features and security features are also described for EHT-LTFs, and signaling of preamble puncturing patterns are defined for 320 MHz physical layer protocol data units (PPDUs) carried in the U-SIG field and in Trigger Frames to improve spectrum efficiency and reduce interference, according to embodiments.
