WIDEBAND-ASSISTED ULTRA-WIDEBAND (UWB) SENSING - A simplified explanation of the abstract
This abstract first appeared for US patent application 17931470 titled 'WIDEBAND-ASSISTED ULTRA-WIDEBAND (UWB) SENSING
Simplified Explanation
The abstract describes a method of ultra-wideband (UWB) sensing using a wireless communication device. The method involves estimating channel impulse responses (CIR) for different frequency channels based on various sessions and stitching them together to create a total CIR estimation.
- The method determines CIR estimations for different frequency channels using both radio access technology (RAT) sessions and UWB sessions.
- It calculates a total CIR estimation for a combined frequency channel by combining the individual CIR estimations.
- The method involves determining phase differences between CIR estimations to improve accuracy.
- By utilizing multiple sessions and CIR estimations, the method aims to enhance the precision of UWB sensing.

Original Abstract Submitted
An example method of ultra-wideband (UWB) sensing performed by a wireless communication device, the method comprising determining a first channel impulse response (CIR) estimation of a first frequency channel based on a radio access technology (RAT) session, wherein the RAT is different from UWB. The method also comprises determining a second CIR estimation of a second frequency channel based on a UWB session and determining a third CIR estimation of the first frequency channel based on determining a phase difference between the third CIR estimation and the first CIR estimation. The method further comprises determining a total CIR estimation for a combined frequency channel comprising the first frequency channel and the second frequency channel based on stitching the first CIR estimation, the second CIR estimation, and the third CIR estimation.
