Abstract
A system and method for using carrier aggregation and enhanced inter-cell interference coordination in carrier scheduling is disclosed. The method comprises scheduling a communication of control channel information from at least one low power node on a physical downlink control channel (PDCCH) over at least one of a first low power component carrier and a second low power component carrier. A sub-frame having a lowest level of interference caused by a corresponding macro component carrier is identified at each corresponding subframe of the component carriers. The identified sub-frame is selected to transmit the control channel information on the PDCCH from the at least one low power node to a mobile wireless device.
