摘要： An illustrated embodiment disclosed herein is a method for downlink scheduling. The method includes scheduling, by a satellite, one or more protocol data units (PDUs) in a slot, determining, by the satellite, whether available capacity of the slot is less than a predetermined threshold, responsive to determining that the available capacity of the slot is not less than the predetermined threshold, scheduling, by the satellite, a second one or more PDUs in the slot, and responsive to determining that the available capacity of the slot is less than that the predetermined threshold, transmitting, by the satellite, the slot to an endpoint. In some embodiments, the one or more PDUs are associated with a first spreading factor (SF). In some embodiments, the first SF is lower than a second SF. In some embodiments, the second one or more PDUs are associated with the second SF.

摘要： An illustrative embodiment disclosed herein is a method including estimating, by an endpoint, a first rate of change of a Doppler frequency offset during a downlink reception from a satellite associated with the Doppler frequency offset and applying, by the endpoint, a second rate of change of the Doppler frequency offset to an uplink transmission to the satellite. The second rate of change of the Doppler frequency offset compensates the first rate of change of the Doppler frequency offset.
