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 13):
The device according to  claim 10 , wherein the processor is configured to:\n when there are a plurality of symbols whose peak-to-average ratios are greater than the preset threshold in the preset quantity of symbols, and Pm\u2212Pn\u2264Pn\u2212Threshold, determine the time offset according to a third formula, where the third formula is:\n TA =( k\u2212 2)* N symb+ Lk\u2212 1, where \n the preset threshold is Threshold, Pm is the largest value in the peak-to-average ratios of the preset quantity of symbols, Pn is the second largest value in the peak-to-average ratios of the preset quantity of symbols, a symbol whose peak-to-average ratio is Pm is an m th  symbol, a symbol whose peak-to-average ratio is Pn is an n th  symbol, TA represents the time offset, Nsymb represents a duration occupied by any symbol in the signal received by the device at the head end, Lk represents a difference between a sampling-point time point corresponding to a peak of a k th  symbol and a start sampling-point time point of the k th  k=min(m, n) symbol, and Lk>0.5 time Nfft, Nfft indicates an FFT length, and m and n are any integers greater than or equal to q.
