Abstract:
A method and an apparatus for determining a time offset are disclosed. The method includes: obtaining, by a device at a head end, a time-domain signal based on a received signal; and then determining a time offset based on values of peak-to-average ratios of a preset quantity of symbols starting from a q th  symbol in the time-domain signal, where a peak-to-average ratio of the q th  symbol is greater than a preset threshold. A new method for determining a time offset is provided, and takes advantages that the time-domain signal obtained by the device at the head end has stronger capabilities of resisting interference such as frequency offset and phase noise. The method for determining a time offset can be applied both to initial ranging and periodic ranging.

Claim (Index 9):
The method according to  claim 2 , further comprising:\n processing, by the device at the head end, a second frequency-domain signal and a frequency-domain reference signal whose parameter is twice an FFT length, to obtain a second frequency-domain result, wherein the frequency-domain reference signal whose parameter is twice the FFT length is obtained based on a frequency-domain reference signal whose parameter is the FFT length in the device at the head end, or the frequency-domain reference signal whose parameter is twice the FFT length is obtained by performing FFT of twice the FFT length on a time-domain reference signal, and the second frequency-domain signal is obtained by performing an FFT of twice the FFT length on the signal received by the device at the head end; and performing, by the device at the head end, an IFFT of twice the FFT length on the second frequency-domain result, to obtain the time-domain signal.
