Abstract: A first and/or a second communications system may provide communications service over a geographic area. A method of operating the first and/or the second communications systems may include generating a measure of aggregate interference reaching a satellite of the second communications system substantially from devices of the first communications system. The measure of aggregate interference reaching the satellite of the second communications system may be transmitted to an element of the first communications system.

Abstract: Wireless communications transceivers include a transmitter that is configured to selectively frequency shift and transmit portions of broadband information over multiple non-contiguous narrowband frequency bands/segments, each of which is too narrow to carry the broadband information. A receiver also is configured to receive and selectively frequency shift portions of broadband information from multiple non-contiguous narrowband frequency bands/segments, each of which is too narrow to carry the second broadband information. Broadband information thereby may be transmitted and received in a regulated communications environment, even though a given provider may only be assigned discontinuous frequency bands/segments, none of which is wide enough to carry the entire broadband information.

Abstract: Wireless communications are transmitted from at least two radioterminals to a base station co-channel over a return link using a return link alphabet. Wireless communications are also transmitted from the base station to the at least two radioterminals over a forward link using a forward link alphabet that has more symbols than the return link alphabet. The co-channel signals are deciphered at the receiver, while the radioterminals can use a smaller return link alphabet, which can reduce the power dissipation at the radioterminals.
