Inter-cell interference coordination in wireless networks

摘要

Systems and method for allocation and optimization of sub-carriers by a plurality of cells based, at least in part, on aspects of user equipment utilizing the wireless communication network. A wireless network management component classifies user equipment with at least a portion of the wireless communication network as cell edge user equipment or cell central user equipment. Based on the classification of the user equipment, the management component determines resource requirements for the cells. The resource requirements can include the designation of sub-carriers as primary sub-carriers and associated power levels based on the designation for the group of cells in the wireless network. Additionally, each cell within the wireless network can utilize the designation of sub-carriers and association of power levels in configuring communications with user equipment.

主权项

1. A method of managing wireless network components, the wireless network components include a set of cells, wherein each cell can be characterized into two or more sectors and wherein the wireless network can be characterized as a set of sectors based on the two or more sectors in the set of cells, the method comprising:
characterizing a plurality of user equipment in the set of sectors as either cell edge user equipment or cell central user equipment; determining a set of power metrics for subcarriers associated with a spectrum of available bandwidth, the set of power metrics determined, at least in part, on the characterization of the plurality of user equipment; modifying the set of power metrics based on interference associated with adjacent sectors; prioritizing a set of sectors based on load at each cell and a number of cell edge user equipment attributed to each of the set of sectors; and for each sector in the set of sectors, dynamically assigning the subcarriers associated with the spectrum of available bandwidth based on subcarriers previously associated with adjacent sectors based on the prioritization of the set of sectors.
