US 2024/0206014 A1 · METHOD, APPARATUS AND SYSTEM FOR IMPROVED DIRECTIONAL MULTIGIGABIT SENSING

Abstract

Efficient and accurate sensing measurements and reporting with multiple responders in 60 GHz WLAN is accomplished by conducting the measurements and reporting in multiple sub-channels separated in a frequency domain, or in a space domain, or both. Measurements, via sensing PPDUs, can be transmitted in parallel in time by multiple devices. Messaging related to communicating reporting of sensing results can also be transmitted in parallel in time by multiple devices. This parallelization is facilitated by the use of the multiple sub-channels in frequency or spatial domain.

Dependent claims

A method for sensing an object using wireless signals, comprising, by a sensing initiator:

wirelessly communicating with a plurality of sensing responders to set up an object sensing measurement;
transmitting, to each of the sensing responders, or receiving from each of the sensing responders, a different respective sensing PPDU on a different respective one of a plurality of sub-channels, the different respective sensing PPDUs being transmitted in parallel in time, the different respective sub-channels differing from one another with respect to carrier frequency and being non-overlapping in frequency domain;
and
obtaining indications of measurements of the plurality of sub-channels based on receipt of the sensing PPDUs by the sensing initiator, or based on receipt of reports from the plurality of sensing responders, the reports generated based on receipt of the sensing PPDUs, the indications of measurements usable to estimate one or more physical characteristics of the object.
