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 10):
A device at a head end, including:\n a processor, a receiver, a memory, and a bus, where the processor is connected to the memory and the receiver via the bus, wherein the receiver is configured to receive a signal including a ranging signal sent by a terminal; and the processor is configured to:\n obtain a time-domain signal based on the signal received by the receiver; and \n determine 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 the time offset is a difference between a first time point and a second time point, the first time point is a time point at which the ranging signal sent by the terminal arrives at the device at the head end, the second time point is a preset reference-point time point, and a peak-to-average ratio of the q th  symbol is greater than a preset threshold, where q is any integer greater than or equal to 1.
