METHOD AND APPARATUS OF MITIGATING INTERFERENCE IN A HETEROGENEOUS NETWORK USING AN INTER-CELL INTERFERENCE COORDINATION

摘要

Methods and apparatuses of mitigating interference in a heterogeneous network using an inter-cell interference coordination are provided. An interference control server assigns, for each of the UE groups, a set of almost blank subframes (ABS) or non-preferred sub-bands specific to the corresponding one of the UE groups based on the UE group interference relationship and a resource demand for each of the UE groups. A base station assigns a plurality of sets of ABS (or non-preferred sub-bands) to reuse time-domain (or frequency-domain) resources.
