Abstract: In a carrier allocation scheme for a cellular communications system, cells are divided into groups of different types (CG1, CG2, CG3, CG4) and carriers (f xyz ) are divided into sets (f 1yz , f 2yz , f 3yz , f 4yz, ) allocated respectively to the different types. Carriers may be re-used between different groups of the same type, and optionally within a group, subject to a minimum re-use distance rule. The allocation patterns may be varied independently between different groups of the same type. The scheme may be adapted to the demand for carriers over a predetermined period. Different allocation schemes applied to different carriers may be overlaid on the same cells. Different allocation schemes may be applied to different cells, provided that the minimum re-use distance rule is obeyed between schemes. The scheme may be applied to spot beams of a satellite communications system, or cells of a terrestrial cellular system.

Abstract: A multibeam is configured to transmit a duplicate of a channel from one spot beam in another spot beam, which contains a remote monitoring station. The satellite is reconfigurable to select the channel which is duplicated, allowing the beams of the satellite to be monitored, without the need for a remote monitoring station in each beam.
