1. An apparatus, for use in a satellite-based communications network, for grouping a plurality of carriers of a carrier resource pool assigned to a spot beam generated by a satellite in said network, and over which signal bursts are transmitted between said satellite and at least one user terminal located in a coverage area of said spot beam, said apparatus comprising:

  • a spot beam segregator which segregates said coverage area into at least one offset zone based on respective propagation time periods required for signals to travel between said satellite and respective different locations in said coverage area; and

    a carrier grouper which groups said carriers into an amount of carrier groups corresponding to an amount of said at least one offset zone, and assigns each of said carrier groups to service a respective one of said at least one offset zone.
