METHOD FOR ESTIMATING TIME OF ARRIVAL BASED ON NON-CONTIGUOUS SPECTRUMS AND APPARATUS - A simplified explanation of the abstract
- 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 signals 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. Finally, a time of arrival estimate is calculated based on the CFR of the full bandwidth, which can be used to determine the location 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.
