Abstract:
An inter-cell interference coordination method and apparatus is provided for a heterogeneous network system based on Orthogonal Frequency Division Multiplexing (OFMD) communication. The inter-cell interference coordination method and apparatus exchanges two different types of inter-cell interference coordination messages between base stations to adaptively use the frequency division and time division schemes, thereby coordinating inter-cell interference of control channels transmitted randomly in distributed manner.
