| 摘要 |
Satellite radiotelephone systems (100) include a space-based component (110) that is configured to provide wireless radiotelephone communications in a satellite footprint over a satellite radiotelephone frequency band (fD, fU). The satellite footprint is divided into a plurality of satellite cells, in which satellite radiotelephone frequencies of satellite radiotelephone frequency band are spatially reused. An ancillary terrestrial network is configured to terrestrially reuse at least one of the ancillary radiotelepho ne frequencies that is used in a satellite cell in the satellite footprint, outside the cell and in some embodiments separated therefrom by a spatial guardband.
