Abstract
Systems and methods are disclosed to address inter-cell interference in a heterogeneous network. In one embodiment, a system is disclosed, comprising: a coordinating node situated between a radio access network and a core network; and a first base station in the radio access network in communication with the coordinating node, wherein: the coordinating node has a coordinating scheduler with a first scheduling period; the first base station has a first base station scheduler with a second scheduling period shorter than the first scheduling period; the coordinating scheduler is configured to send a resource reservation list and a resource restriction list to the first base station scheduler once during each first scheduling period; and the first base station is configured to receive the resource reservation list and the resource restriction list and to use the resource reservation list and the resource restriction list when performing mobile device resource scheduling.
