Allocation of Downlink Carrier Power in LEO Communication Satellites
A method is provided for simultaneously transmitting a plurality of signals from a LEO satellite towards a plurality of ground terminals located within a pre-defined range of distances from the LEO satellite, wherein the plurality of signals have a pre-defined overall capacity; at least two of the plurality of signals have each a power level that is different from a power level of the other of the at least two signals; and each signal transmitted to a respective ground terminal is selected so as to ensure that its power level is the lowest from among the signals that are simultaneously transmitted, yet the selected signal has a sufficient power to enable its proper reception at a distance which extends between the respective ground terminal and the LEO satellite.
Systems and methods for communicating data over satellites
Systems for communicating data through a satellite are disclosed. The systems generally include a radio designed for terrestrial communications that is configured to uplink data to one or more satellites. The one or more satellites are configured to receive the data from the terrestrial radio. In addition, the systems include terrestrial receivers, such as one or more chirp spread spectrum radios, positioned at ground level, which are configured to receive the data from the one or more satellites.
Terrestrial and non-terrestrial communication systems, apparatuses, and methods
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.
Satellite payload with full downlink spectrum usage
Satellite communication methods and payloads are described. The payload and methods are designed to enable effective use of carrier signals in the guard band region of a channelized band of spectrum. An on-board digital channelizer may implement a band edge power monitor for measuring power spectral density in the band edges of a channel and, if it exceeds a preset threshold level, downscaling the signal amplitude in the band edges to prevent hardware damage to the payload. The channelizer may further implement a band edge gain adjustment filter for shaping the overall frequency response to flatten the response across adjacent channels, including through the guard band region between the passbands of the adjacent channels.

Simultaneously broadcasting acknowledgements of reception of uplink wireless communication
Apparatuses, methods, and systems for communicating through a wireless link are disclosed. A method includes scheduling, by a server, communication between a base station and a plurality of hubs, receiving, by the base station, the scheduled communication, providing, to each hub, a data profile that includes a periodicity, an offset, and a carrier frequency based on the scheduled communication, receiving, by the base station, uplink wireless communication from each of the plurality of hubs according to the data profile of each of the hubs and according to the scheduled communication, and simultaneously broadcasting, by the base station, acknowledgements of reception of uplink wireless communication from each of the plurality of hubs.
Phase array routing connectivity
A communication system has a control module with a control processing device, and a plurality of common modules. Each of the common modules has a common processing device. The control module and the plurality of common modules are connected with at least one adjacent common module to form a communication array. The control module and the common modules communicate via a first routing path having a first path of common modules of the plurality of common modules, and a second routing path having a second path of common modules of the plurality of common modules different than the first path of common modules. The control module and the plurality of common modules communicate via the second routing path when one of the first set of common modules fails.
Satellite acquisition assistance for supporting satellite wireless access by a mobile device
Methods and techniques are described for supporting satellite wireless by a user equipment (UE) using satellite acquisition information. A UE may obtain (e.g., from an AMF or gNB) acquisition information for satellite cells supporting access to a PLMN. The UE may enter an inactive state with no radio access, may later leave the inactive state, find a preferred satellite cell based on the acquisition information and access the satellite cell (e.g., camp on the cell or connect to the PLMN using the cell). The acquisition information may indicate satellite cells available at one or more predefined times for a known location of the UE or may enable a satellite cell to be found for any UE location at any time. The acquisition information may also provide timing, frequency and other information to enable a UE to access a satellite cell with reduced latency and reduced power consumption.
DYNAMIC ON-DEMAND CONNECTIVITY TO ADVANCED COMMUNICATION NETWORKS VIA SATELLITE
Dynamic, on-demand connectivity via satellite is enabled for advanced communication networks, such as, but not limited to, fifth generation (5G) communication networks and beyond. For instance, a system comprises radio equipment part of a new radio (NR) communication network that facilitates communication of data traffic between a communication device and core equipment of the NR communication network via satellite communication equipment part of a satellite communication network, wherein the radio equipment facilitates the communication using a NR communication protocol defined for the NR communication network. In one or more embodiments, the NR network comprises a 5G network and wherein the NR communication protocol comprises a 5G communication protocol.
