Abstract
Embodiments of the claimed subject matter provide a method and apparatus performing inter-cell load-balancing and inter-cell interference coordination. Some embodiments of the method include partitioning cells into groups that include a different subset of the plurality of cells. Embodiments of the method also include iteratively repeating, until a convergence criterion is satisfied, steps that include determining one or more associations of user equipment to one or more cells for a previously determined allocation of resources to the groups and determining the allocation of resources to the groups for a previously determined association of user equipment to the cells.
Claims20
A method, comprising:
- partitioning cells into groups that comprise different subsets of the cells;
- iteratively repeating, until a convergence criterion is satisfied, steps comprising:
- determining one or more associations of user equipment to one or more of the cells for a previously determined allocation of resources to the groups;
- and
- determining an allocation of resources to the groups for a previously determined association of user equipment to the cells.
An apparatus, comprising:
- a controller configured to partition cells into groups that comprise different subsets of the cells,
- wherein the controller is configured to iteratively repeat, until a convergence criterion is satisfied, steps comprising:
- determining one or more associations of user equipment to one or more of the cells for a previously determined allocation of resources to the groups;
- and
- determining an allocation of resources to the groups for a previously determined association of user equipment to the cells.
A non-transitory computer-readable storage medium encoded with instructions that, when executed by a processing device, adapt the processing device to perform a method, the method comprising:
- partitioning cells into groups that comprise different subsets of the cells;
- iteratively repeating, until a convergence criterion is satisfied, steps comprising:
- determining one or more associations of user equipment to one or more of the cells for a previously determined allocation of resources to the groups;
- and
- determining an allocation of resources to the groups for a previously determined association of user equipment to the cells.
