ENHANCEMENT OF INTER-CELL INTERFERENCE COORDINATION WITH ADAPTIVE REDUCED-POWER ALMOST BLANK SUBFRAMES BASED ON NEIGHBOR CELL PROFILE DATA
First Claim
1. A system, comprising:
- a processor; and
a memory that stores executable instructions that, when executed by the processor, facilitate performance of operations, comprising;
receiving cell profile information representing features associated with a metro cell access point device; and
based on the cell profile information, determining transmission power data representing a transmission power of a macro cell access point device that is employable to facilitate inter-cell interference coordination between the macro cell access point device and the metro cell access point device.

Abstract
An inter-cell interference coordination procedure in heterogeneous networks (HetNets) is enhanced based on utilization of cell profile data associated with neighbor access points to improve HetNet spectrum efficiency, mobility performance, and/or overall network capacity. In one aspect, a macro access point can receive cell profile data associated with neighbor access points and modify a power level of reduced-power almost blank subframes (ABS) transmitted by the macro access point to manage macro cell capacity. Further, the macro access point can configure the ABS pattern and transmit the ABS pattern to the neighbor access points. Based on the ABS pattern, the neighbor access points can schedule transmissions to user equipment that are located at (or close to) their cell-edge to reduce inter-cell interference.
