Abstract:
1. A method for communications controller operation, the method comprising: receiving dominant-only interferer information comprising channel quality information from a first communications device served by the communications controller, wherein the channel quality information comprises a channel state information matrix and interference information for a channel between the first communications device and a neighboring interferer, and wherein the channel state information matrix is different from the interference information; scheduling a cell edge communications device for downlink communication in accordance with the received dominant-only interferer information, wherein the cell edge communications device operates in a periphery of a coverage area of the communications controller, and wherein the cell edge communications device is scheduled to a subset of downlink resources reserved for the cell edge communications device; reporting usage information of the subset of resources to neighboring communications controllers; from each of the neighboring communications controllers, receiving neighboring usage information of a neighboring subset of resources reserved for cell edge communications devices served by the respective neighboring communications controller; scheduling a cell center communications device, for downlink communication, in accordance with the received neighboring usage information from the neighboring communications controllers, wherein the cell center communications device is scheduled to downlink resources not in the subset of downlink resources; and transmitting data to scheduled communications devices over their respective scheduled downlink resources.
