US 2026/0086221 A1 · FRAME OF REFERENCE COORDINATION BETWEEN WIRELESS DEVICES

Abstract

Techniques for coordinating a frame of reference between wireless devices may comprise determining a displacement vector of a wireless mobile device with respect to its local coordinate system, the displacement vector indicative of a displacement of the wireless mobile device between a first time and a second time. Techniques may further comprise the wireless mobile device receiving, from a first wireless reference device, an indication of a displacement vector of the wireless mobile device with respect to a common reference direction, and adjusting an estimated alignment of the common reference direction with respect to the wireless mobile device's local coordinate system, based at least in part on correction information determined from a comparison of (i) the displacement vector of the wireless mobile device with respect to its local coordinate system with (ii) the displacement vector of the wireless mobile device with respect to the common reference direction.

A method of coordinating a frame of reference between wireless devices, the method comprising:

determining, at a wireless mobile device, a displacement vector of the wireless mobile device with respect to a local coordinate system of the wireless mobile device, the displacement vector indicating a set of one or more attributes of displacement from a location of the wireless mobile device at a first time to a location of the wireless mobile device at a second time;
receiving, at the wireless mobile device from a first wireless reference device, an indication of a displacement vector of the wireless mobile device with respect to a common reference direction;
and
adjusting, at the wireless mobile device, an estimated alignment of the common reference direction with respect to the local coordinate system of the wireless mobile device, wherein the adjusting is based at least in part on correction information determined from a comparison of:
(i) the displacement vector of the wireless mobile device with respect to the local coordinate system of the wireless mobile device with
(ii) the displacement vector of the wireless mobile device with respect to the common reference direction.

3 more elements

A wireless mobile device comprising:

at least one transceiver;
at least one memory;
and
at least one processor communicatively coupled with the at least one transceiver and at least one memory, the at least one processor configured to:
determine a displacement vector of the wireless mobile device with respect to a local coordinate system of the wireless mobile device, the displacement vector indicating a set of one or more attributes of displacement from a location of the wireless mobile device at a first time to a location of the wireless mobile device at a second time;
receive, via the at least one transceiver from a first wireless reference device, an indication of a displacement vector of the wireless mobile device with respect to a common reference direction;
and
adjust an estimated alignment of the common reference direction with respect to the local coordinate system of the wireless mobile device, wherein the adjusting is based at least in part on correction information determined from a comparison of:
(i) the displacement vector of the wireless mobile device with respect to the local coordinate system of the wireless mobile device with
(ii) the displacement vector of the wireless mobile device with respect to the common reference direction.
