摘要
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.
