  • Publication number: 20240056177
    Abstract: A method carried out in a UE (1) for estimation of a parameter of a communication link, such as Timing Advance, for use in communication with an orbiting satellite-based access node (141) of a non-terrestrial network (130). The method comprises determining, at repeated occasions, a time of reception (Tk) in the UE of a reference signal which is transmitted with a predetermined period (?P) from the access node. A value of the parameter is calculated based on a position (51,52) which satisfies a spatial condition for the UE, which spatial condition is given by a propagationtime difference (?k) of the reference signal between said occasions (Tk, Tk+1).
