Abstract:
1. A method, comprising: determining, in at least one server, neighbor relationships between a plurality of sectors; constructing, in the at least one server, a precedence graph using the neighbor relationships to link neighboring sectors by a plurality of directed arcs to indicate relative precedence of the neighboring sectors; and iteratively allocating, in the at least one server, at least one antenna resource of each of the plurality of sectors by: selecting a subset of the plurality of sectors as master sectors, wherein each master sector is associated with at least one slave sector that neighbors the master sector, and wherein each master sector has precedence over its associated slave sectors, and wherein each slave sector is only associated with one master sector; concurrently optimizing allocation of said at least one antenna resource for each master sector and its associated slave sectors; reversing precedence indicated by the directed arcs linked to each master sector following optimization of the allocation of said at least one antenna resource; and iterating so that each of the plurality of sectors is selected as a master sector for at least one iteration.
