Abstract: The present disclosure relates to a 5G or 6G communication system for supporting higher data transmission rates than 4G systems such as LTE. A method for operating a proxy in a wireless communication system combining a terrestrial network and a satellite network according to an embodiment of the present invention comprises the steps of: acquiring, from a server for managing a satellite, configuration information about a satellite cell that connects with a user equipment in which a transport control protocol (TCP) session is to be set up; calculating a first round trip time (RTT) between the satellite cell and the satellite and the data rate of the satellite cell on the basis of the configuration information about the satellite cell; and setting a congestion window (CWND) value for the TCP session on the basis of the first RTT and the data rate of the satellite cell.

Abstract: A constellation of many satellites provide communication between devices such as user terminals (UTs) and ground stations that are connected to other networks, such as the Internet. A constellation management system (CMS) facilitates management and operation of the satellites in the constellation and facilitates information exchange with other authorized systems to provide for situationally aware operation. The CMS may ingest data such as satellite telemetry, space weather data, object ephemeris data about other orbital objects, and so forth. The CMS uses the ingested data to automatically operate satellites to perform routine activities such as station keeping maneuvers, maintenance activities, interference mitigation, and so forth. Confirmation from a human operator may be obtained before performing some activities. Activities may be planned and coordinated to minimize resource consumption for the individual satellite as well as the constellation. Output, such as ephemeris data, may be provided to other parties as well.

Abstract: A satellite communication system and method are presented for operation in one or more frequency bands to simultaneously relay data signals between a plurality of remote terminals and one or more ground stations (gateways) in both return and forward links. This allows the remote terminal to be of a few centimeters in size. The satellite communication system comprises a processor configured and operable to receive from each of the remote terminals an uplink return signal in the form of a plurality of terminal return signals spread over a predetermined first frequency allocation in said one or more frequency bands according to a predetermined spread function, de-spread the received plurality of terminal return signals, and generate a downlink return signal, corresponding to at least some of the received plurality of spread terminal return signals and having a predetermined second frequency allocation, to be sent to one of the ground stations.
