TECHNIQUES FOR WIDE BANDWIDTH POSITIONING IN A WIRELESS LOCAL AREA NETWORK - A simplified explanation of the abstract
- This abstract for appeared for US patent application number 17722197 Titled 'TECHNIQUES FOR WIDE BANDWIDTH POSITIONING IN A WIRELESS LOCAL AREA NETWORK'
Simplified Explanation
The abstract describes methods, systems, and devices for wireless communications that support greater bandwidths for ranging null data packets (NDPs). These designs allow for the use of a 320 MHz bandwidth, which offers higher resolution than narrower bandwidths. The signaling and messaging designs include updates for various frames such as null data packet announcement (NDPA) frame, trigger frame, session negation messages, and segmentation techniques for ranging NDPs.
Original Abstract Submitted
Methods, systems, and devices for wireless communications are described. In some aspects, two devices may support signaling and messaging designs that support bandwidths that are greater than 160 MHz for ranging null data packets (NDPs). For example, various signaling and messaging designs may support a use of a 320 MHz bandwidth for ranging NDPs as part of a ranging measurement procedure, which may offer greater resolution than narrower bandwidths. The signaling and messaging designs may include one or more updates for a null data packet announcement (NDPA) frame, for a trigger frame, for session negation messages (such as one or both of an initial fine timing measurement (IFTM) frame and an IFTM request (IFTMR) frame), for segmentation techniques for ranging NDPs, or for any combination thereof.
