Lockheed Martin Corp. has filed a patent for systems and methods for communication in 4G and 5G broadband satellite networks. The methods disclosed include GNSS-independent methods and GNSS-assisted methods that eliminate the need for transmitting satellite ephemeris information from a base station to user equipment. The patent outlines a method for communication in a broadband satellite network involving a base station, terminal device, and satellite. The method includes receiving a downlink frame, determining arrival and transmission times of the frame, calculating a timing advance based on these times and error terms, and advancing subsequent communications accordingly. The patent also describes a base station for communication in a broadband satellite network, equipped with processing units to provide downlink frames, establish conventions with terminal devices, receive timing advances, and handle subsequent communications based on these advances.
Additionally, the patent details a method for communication in a terrestrial broadband network involving a base station and terminal device. This method includes iterative PRACH preamble detection operations at the base station, determining a differential delay based on received PRACH preambles, and using this delay for subsequent communications between the base station and terminal device. The base station determines the differential delay as a timing advance and provides this information to the terminal device for advancing subsequent communications. These innovative methods and systems proposed by Lockheed Martin Corp. aim to enhance communication efficiency and reliability in broadband satellite and terrestrial networks, particularly in the context of 4G and 5G technologies.
