US 12,267,709 B2 · Techniques for wide bandwidth positioning in a wireless local area network

Abstract

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.

Dependent claims

An apparatus for wireless communication at a first device, comprising:

one or more processors;
and
one or more memories coupled with the one or more processors and that store processor-executable code that, when executed by the one or more processors, is configured to cause the apparatus to:
receive a physical layer protocol data unit (PPDU) that includes a ranging null data packet announcement (NDPA) frame, wherein the PPDU includes an indication of a bandwidth of ranging null data packets (NDPs) to be used for a ranging measurement procedure between the first device and a second device, the bandwidth of the ranging NDPs being greater than 160 megahertz (MHz), and an indication of a puncturing pattern that is associated with the bandwidth of the ranging NDPs being greater than 160 MHZ, and
receive a first set of one or more ranging NDPs based at least in part on the indication of the bandwidth and the indication of the puncturing pattern that is associated with the bandwidth of the ranging NDPs being greater than 160 MHz,
wherein a distance between the first device and the second device is based at least in part on measurements made of the first set of one or more ranging NDPs.
