  • Publication number: 20220182959
    Abstract: A method and an apparatus for obtaining timing advance value. The method comprises: receiving (S101) a time domain signal, which contains at least part of a reference signal; extracting (SI 02), from the time domain signal, a first group of signal parts including at least one signal part, and a second group of signal parts including at least one signal part, wherein the first group of signal parts do not overlap the second group of signal parts; and determining (S103) a timing advance, TA, value based on an energy of a signal part in the first group of signal parts and an energy of a signal part in the second group of signal parts, wherein the energy of the signal part is based on correlation between the signal part and the reference signal. Therefore, the TA value may be obtained based on a time domain signal.
