  • This abstract for appeared for patent application number 18335694 Titled 'METHOD FOR ESTIMATING TIME OF ARRIVAL BASED ON NON-CONTIGUOUS SPECTRUMS AND APPARATUS'

Simplified Explanation

The abstract describes a method and apparatus for estimating the time of arrival of a signal based on non-contiguous spectrums. The method involves receiving multiple signals on different frequency bands, determining the channel frequency responses (CFRs) of these frequency bands, and then using these CFRs to determine a CFR of the full bandwidth. The time of arrival estimate is then calculated based on the CFR of the full bandwidth, and this estimate is used to determine the location information of a terminal device.


Original Abstract Submitted

A method for estimating a time of arrival based on non-contiguous spectrums and an apparatus are provided. The method includes: receiving a plurality of signals from a transmit end on a plurality of frequency bands; determining, based on the plurality of signals, channel frequency responses CFRs of the frequency bands corresponding to the plurality of signals; determining a CFR of full bandwidth based on the CFRs of the frequency bands corresponding to the plurality of signals, where the full bandwidth includes the plurality of frequency bands; and determining a time of arrival estimate based on the CFR of the full bandwidth, where the time of arrival estimate is used to determine location information of a terminal device.
