SATELLITE SIGNAL PROPAGATION DELAY VARIATION COMPENSATION

Satellite signal propagation delay variation can be compensated by transmitting ephemeris data of a satellite and cell measurement window specifications to a terminal, receiving an indication from the terminal that a cell measurement signal will arrive at the terminal outside of a time frame defined by the cell measurement window specifications, modifying the cell measurement window specifications based on a difference in propagation delay between a serving cell, which defines the cell measurement window specifications, and a neighboring cell, which transmits the cell measurement signal, so that the cell measurement signal will arrive at the terminal within the time frame defined by the cell measurement window specifications, the satellite providing communication with the terminal for at least one of the serving cell and the neighboring cell, and transmitting modified cell measurement window specifications to the terminal.
