Abstract: Information is transmitted from a radioterminal to a first base station via a first wireless link. A satellite is used to route the information from the first base station to a second base station via second wireless links between the satellite and the first base station and between the satellite and the second base station. At least one of the second wireless links is more spectrally efficient than the first wireless link. Related methods, systems and devices are disclosed.

Abstract: A satellite communications system includes a satellite that is configured to wirelessly communicate with radioterminals in a satellite coverage area over a satellite frequency band, and an ancillary terrestrial component that is configured to wirelessly communicate with radioterminals in the satellite coverage area over at least some of the satellite frequency band, to thereby terrestrially reuse at least some of the satellite frequency band. Wireless communications with a radioterminal are handed over from the ancillary terrestrial component to the satellite if the radioterminal transmit power exceeds a threshold, and a received satellite signal quality exceeds a threshold, even though the radioterminal is able to wirelessly communicate with the ancillary terrestrial component. Downlink wireless radiation that is received at the radioterminal from a satellite may be monitored to determine potential interference created by the uplink radiation of the radioterminal due to the terrestrial reuse of at least some of the satellite frequency band.

Abstract: First radio signals are received by a first satellite, the received first radio signals including a desired satellite uplink signal transmitted from a first source using a frequency assigned to the first source and an interfering signal transmitted from a second source using the frequency assigned to the first source. The first radio signals are combined based on a first performance criterion to generate a first output signal. Second radio signals are received by a second satellite, the received second radio signals including a measure of the desired signal. The second radio signals are combined based on a second performance criterion to produce a second output signal. The first and second output signals are combined to generate an estimate of the desired satellite uplink signal.

Abstract: A first radio signal is received via a first satellite reception path, for example, an antenna or spot beam, which serves a satellite cell. The received first radio signal includes a desired satellite uplink signal transmitted from a first source using a frequency assigned to the satellite cell and an interfering signal transmitted from at least one second source using the frequency assigned to the satellite cell. A second radio signal is received via a second satellite reception path, for example, via another antenna or spot beam of the system and/or via a satellite antenna beam of another system. The second radio signal includes a measure of the interfering signal. The first and second radio signals are processed to recover the desired satellite uplink signal.

Abstract: Methods and systems for low earth orbit satellite communications, utilizing fractionated satellites and constellations with large baselines. The latter, combined with spatial multiplexing protocols, provides access to user equipment on the ground with much greater spatial resolution than hitherto possible. Methods include overcoming the problem posed by the round-trip delay of satellite links when adaptive, downlink, beamforming is attempted in Frequency Division Duplex (FDD) systems. Methods include using of uplink and downlink pilot signals which eliminate the need for controlling the physical integrity of the fractionated satellite through an electromechanical servo-control system in space.
