Title:
SYSTEMS AND METHODS FOR SENSING VIA INTERFEROMETER TECHNIQUES FOR SUBTERAHERTZ MIMO SYSTEMS
Document Type and Number:
WIPO Patent Application WO/2024/016231
Kind Code:
A1
Abstract:
Provided using interferometry for sensing movement of an object in a communications network operating at high frequency. The interferometer may achieve high accuracy without requiring large overhead resulting from using very narrow beams that are generated via very large antenna panels. The distance between slits does not need to be large to achieve high resolution due to the short wavelength (λ) at high frequency. Therefore, considering multi-panel, or multi-portion panel transmission, the distance between panels, or portions of a panel, may be sufficient to achieve high accuracy, even considering the case of the single panel that is virtually divided into two or more subpanels by controlling the phase shifts in each subpanels. Provided methods of signaling associated with an over-the-air (OTA) interferometer between a transmitter and receiver for measuring movement of an object.
