1. A non-transitory computer-readable medium including instructions that are executable by a computer to cause the computer to perform operations comprising:
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;
wherein the modifying the cell measurement window specifications includes determining that a spectral efficiency of the modified cell measurement window specifications is above a threshold spectral efficiency value.
