Abstract: A satellite radiotelephone frequency band can be reused terrestrially by an ancillary terrestrial network even within the same satellite cell, using interference reduction/cancellation techniques. An interference reducer is responsive to a space-based component and to an ancillary terrestrial network. The interference reducer is configured to reduce interference in wireless communications that are received by the space-based component from first radiotelephones in the satellite footprint over a satellite radiotelephone frequency band using wireless communications that are received by the ancillary terrestrial network from selected ones of second radiotelephones in the satellite footprint over the satellite radiotelephone frequency band and/or wireless communications that are transmitted by the ancillary terrestrial network to the second radiotelephones in the satellite footprint over the satellite radiotelephone frequency band. The interference reducer may include a prefilter that is configured to determine the selected ones of the second radiotelephones.

Abstract: An Ancillary Terrestrial Network (ATN) includes at least one Ancillary Terrestrial Component (ATC) that is configured to provide wireless communications using frequencies of a satellite frequency band. The ATN provides communications based on a GSM, cdma2000 and/or W-CDMA air interface, under a constrained capacity measure. The capacity measure of the ATN may also be constrained when the ATN provides communications based on an Orthogonal Frequency Division Multiplexed (OFDM) and/or Orthogonal Frequency Division Multiple Access (OFDMA) air interface. Analogous methods of controlling an ATN also may be provided.

Abstract: A satellite communications system includes a plurality of feeder link antennas, a primary satellite, and an auxiliary satellite. The feeder link antennas are substantially co-located relative to one another. The primary satellite is configured to receive information over a plurality of return service links from radioterminals, to communicate a first portion of the information over at least one return feeder link directly to a first one of the feeder link antennas, and to communicate a second portion of the information over at least one inter-satellite link. The auxiliary satellite is spaced apart from the primary satellite, and configured to receive the second portion of the information from the primary satellite via the at least one inter-satellite link, and to communicate the second portion of the information across at least one return feeder link to a second one of the feeder link antennas.

Abstract: Methods of reducing interference in wireless communications in a communications system are provided. A wireless communications signal is received within a frequency band. The wireless communications signal includes a desired component and an undesired interference component. The interference component may be caused by, for example, communications by another component of the communications system using frequencies in the frequency band. The received communications signal is converted to a frequency domain representation. Frequencies of the interference component of the frequency domain signal are identified. At least some of the identified frequencies of the interference component of the frequency domain signal are attenuated to generate an interference attenuated frequency domain signal. The interference attenuated frequency domain signal is converted to an interference attenuated time domain signal.
