Abstract
A method for estimating a time of arrival based on non-contiguous spectrums includes receiving a plurality of signals from a transmit end on a plurality of frequency bands. The plurality of frequency bands are in a one-to-one correspondence with the plurality of signals. The method also includes determining, based on the plurality of signals, channel frequency responses (CFRs) of the frequency bands corresponding to the plurality of signals. The method further includes determining a CFR of a full bandwidth based on the CFRs of the frequency bands corresponding to the plurality of signals. The method additionally includes determining a time of arrival estimate based on the CFR of the full bandwidth. The time of arrival estimate is used to determine location information of a terminal device.
