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 20):
The machine-readable medium according to  claim 19 , wherein the determining, by the device at the head end, a time offset based on values of peak-to-average ratios of a preset quantity of symbols starting from a q th  symbol comprises:\n when there is one symbol whose peak-to-average ratio is greater than the preset threshold in the preset quantity of symbols, and the symbol whose peak-to-average ratio is greater than the preset threshold is the q th  symbol, determining, by the device at the head end, the time offset according to a first formula, wherein the first formula is:\n TA =( q\u2212 2)* N symb+ Lq\u2212 1, wherein \n TA represents the time offset, Nsymb represents a duration occupied by any symbol in the signal received by the device at the head end, and Lq represents a difference between a sampling-point time point corresponding to a peak of the q th  symbol and a start sampling-point time point of the q th  symbol.
