Abstract:
1. A method for transmitting messages for inter-cell interference coordination of a source base station and a target base station in a heterogeneous cellular system, the method comprising the steps of: generating, by the source base station, first inter-cell interference coordination information and second inter-cell interference coordination information, the first inter-cell interference coordination information and the second inter-cell interference coordination information being associated with a first subframe and a second subframe, respectively; transmitting, by the source base station to the target base station, the first inter-cell interference coordination information, the second inter-cell interference coordination information, a resource allocation bitmap indicating an allocation structure of at least one of the first inter-cell interference coordination information and the second inter-cell interference coordination information, and time information indicating at least one of the first subframe and the second subframe; and applying, by the source base station, the first inter-cell interference coordination information and the second inter-cell interference coordination information to the at least one of the first subframe and the second subframe.
