Definitions

  • inter-cell-interference co-ordination/avoidance The approaches considered in inter-cell interference mitigation comprise inter-cell-interference co-ordination/avoidance.
  • the common theme of inter-cell-interference co-ordination/avoidance is to apply restrictions to the resource management (configuration for the common channels and scheduling for the non common channels) in a coordinated way between cells. Such restrictions in a cell will provide the possibility for improvement in (Signal-to-Interference Ratio) SIR, and cell-edge data-rates/coverage, on the corresponding time/frequency resources in a neighbor cell.
  • the exemplary frequency groups 32 , 33 , 34 , 35 , 36 of FIG. 3 are shown as comprised of one or more adjacent radio frequency carriers. It is clear that the radio resource groups according to the invention may comprise any logical combination of a number of related radio resource units that for a purpose can be dealt with as an entity.
  • a radio resource group can consist of a number of (for example 2-4) physical radio resource units that may, or may not reside next to each other in the frequency domain.
