Patent ID: 8463178

Claim:
A communication system comprising: at least a first radio terminal comprising a first transceiver including at least a first receiver and at least a first transmitter that communicates by way of a satellite using a satellite frequency band; at least a second radio terminal comprising a second transceiver including at least a second receiver and at least a second transmitter that communicates by way of the satellite using the satellite frequency band and that selectively communicates with the first radio terminal via a wireless terrestrial link using a portion of the satellite frequency band so as to terrestrially reuse the portion of the satellite frequency band; a device, collocated with the first transceiver, that measures power received by the satellite over a frequency band from all sources including the wireless terrestrial link, and transmitted from the satellite to the first receiver; and a controller that receives and processes said measurements to determine in which frequency channel within the satellite frequency band the second transmitter is to transmit.
