    摘要： A communications system includes a space-based network (SBN) including a plurality of spotbeams using a first set of frequencies and an ancillary terrestrial network (ATN) including a plurality of base stations using a second set of radio frequencies. In a coverage zone of a given spot beam wherein the SBN and the ATN use at least one frequency from the first and second sets of frequencies in common, the SBN uses a narrower bandwidth than the ATN on both forward and return links, the ATN employs frequency spreading on at least its return link communications, the SBN employs spatial beam nulling directed toward at least one ancillary terrestrial component (ATC) of the ATN, the SBN employs forward link margin control, the ATN employs return link power control, the SBN employs return link power control and base stations of the ATN provide isolation in the direction of at least one satellite of the SBN. Using such a combination of measures, the ATN and the SBN may support completely or partially overlapping use of the first and second sets of radio frequencies.

    摘要： A Frequency Division Duplex (FDD) wireless terminal includes spaced-apart antennas that are configured to transmit over a return link and to receive over a forward link that is spaced apart from the return link in frequency. The FDD wireless terminal is configured to selectively refrain from transmitting over the return link from at least one of the spaced-apart antennas of the FDD wireless terminal in response to differentials in forward link power that is received at the spaced-apart antennas of the FDD wireless terminal, that are caused, for example, by blocking appendages of a user of the wireless terminal. Related methods are also described.

    摘要： In some embodiments, a satellite communications network dynamically regulates carrier assignment for bidirectional communications between a satellite and radioterminals. The satellite communications network includes a resource manager that regulates the carrier assignments by selecting among a plurality of FDD return subcarriers, with potentially different subcarrier bandwidths and supporting different radio access technologies, within at least one FDD return carrier grouping for coupling to a selected one of a plurality of FDD forward carriers, and by controlling the satellite network to receive communications from the radioterminal on the selected FDD return subcarrier and to transmit communications to the radioterminal on the selected FDD forward carrier.

    摘要： 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.
