Embodiments of the present invention include a two-stage blending filter that blends the measurements from two angular sensors to form a single superior high bandwidth measurement for improved disturbance rejection in a satellite systems for increased accuracy in satellite pointing, orientation, and attitude control. Embodiments of the present invention can include a satellite system including a first sensor including or defining a first measurement bandwidth; a first filter connected to the first sensor; a second sensor including or defining a second measurement bandwidth; a second filter connected to the second sensor; and a third filter connected to the first filter and the second filter. The third filter blend the first signal and the second signal into a third signal; and transmit the third signal to a flight controller configured to adjust an orientation of the satellite, a satellite subsystem, or both, relative to a target in response to the third signal.

The present disclosure relates, in part, to non-terrestrial communication systems, and in some embodiments to the integration of terrestrial and non-terrestrial communication systems. Non-terrestrial communication systems can provide a more flexible communication system with extended wireless coverage range and enhanced service quality compared to conventional communication systems.

A frequency resource allocation apparatus comprising a processor is configured to select resources for transmitting a signal to a user based on a learning model, allocate the selected resources to the user, transmit the signal to the user using the selected resources, receive information about whether the transmission of the signal is successful or not from the user via a feedback channel after a delayed time, and update an internal parameter of the learning model with respect to the resources used for transmitting the signal.

A method implemented by a user equipment to access a satellite network, at least one satellite of the satellite network being in movement relatively to Earth, the satellite network deploying radiofrequency satellite beams, wherein the user equipment: receives through at least a first satellite beam data of assistance information regarding at least current and future satellite beams of the network, interprets the data of assistance information to anticipate: connection conditions through the first satellite beam, and connection conditions through at least one second satellite beam, different from the first satellite beam, decides the access to the satellite network through a satellite beam among the first satellite beam and the second satellite beam, selected on the basis of at least the connection conditions through the first and second satellite beams, and implements a RACH procedure through the selected satellite beam.

A method for matching between high altitude platform (HAP) and unmanned aerial vehicle (UAV) in space-air-ground integrated network includes determining if there is an unmatched UAV in the space-air-ground integrated network including at least one UAV and at least one HAP; requesting matching to an unmatched m-th (where m is a natural number) UAV from an n-th (where n is a natural number) HAP having an unconnected antenna in a presence of the unmatched UAV; determining if the m-th UAV is matched with another HAP; comparing a priority of the n-th HAP with a priority of the matched HAP, in case of the m-th UAV being matched with another HAP; and matching the unconnected antenna of the n-th HAP with the m-th UAV, in case of the priority of the n-th HAP being higher than the priority of the matched HAP.

A user equipment (UE) accesses a public land mobile network (PLMN) and obtains an address of a server and authorization data. The UE sends the server a request for coverage data based on the address and including the authorization data. After verifying the authorization data, the server sends the coverage data to the UE, which enables the UE to determine whether access to the PLMN is possible at one or more locations of the UE, at one or more future times, and using one more radio access technologies (RATs), including non-terrestrial network (NTN) RAT(s) and/or terrestrial network (TN) RAT(s). The authorization data may include a temporary identifier for the UE that may be ciphered and may enable verification of the authorization data. The request for coverage data may indicate signal levels needed by the UE to access the NTN and TN RATs and the locations and the future times.

Systems, methods and techniques are presented for discovering optimal solutions to satisfy communication traffic demands to a NGSO and GSO satellite constellations used for telecommunication. When multiple ground demands (mobile and stationary) are present, a satellite constellation requires an assignment of satellite resources to optimally match the ground demands. The systems, methods and techniques presented can utilize an optimization structure to maximize the objective function, using linear programming in combination with simulation and predictive features. The techniques presented determine optimal or quasi-optimal allocation of scarce and highly constrained satellite resources in an efficient manner. These techniques take into account maximizing capacity while protecting other geostationary and non-geostationary networks.

In one embodiment, a method performed by a wireless communication device operating in a non-terrestrial network (NTN), the method including: obtaining configuration information associated with a plurality of candidate cells of the NTN, each of the plurality of candidate cells associated with a respective one of a plurality of candidate satellites; and based on the configuration information, adjusting a ranking of the plurality of candidate cells for cell selection or reselection.

The invention provides a method and an architecture for deploying non-terrestrial cellular network base stations, so as to enable cellular network coverage in remote areas, where no fixed infrastructure is available. The proposed methods allow for efficient power management at the terminal devices that need to synchronize to the airborne or spaceborne cellular base stations. This is particularly important for IoT devices, which have inherently limited power are computing resources.
