Abstract

Systems and methods for providing relay support in a communications system is provided. A relay node communication network node is provided. Aggregation of component carriers is used. At least one of the aggregated component carriers is split in to two sub-bands. One sub-band is used to form the wireless backhaul connection between the RN and a base station or e NB. The other sub-band is used to provide a direct link between the e NB and other user equipment or UEs. By splitting the carrier into sub-bands, and by using the aggregated band ("C2") with original band ("C1") in a manner where they are spatially separated, efficient communication between the e NB, the RN, and its attached UEs, and with minimal relay delays and interference problems, is achieved.
