LINK ADAPTATION IN TYPE-II RELAY NETWORK

摘要

This invention is related to the link adaptation for the downlink transmission in type-II relay network. An method in an eNodeB for adapting link for downlink transmission in type- II relay network, said type- II relay network comprises the eNodeB, one or more relay nodes and a plurality of User Equipments (UE), the method comprises the steps of: classifying the plurality of UEs into two groups: macro-UEs which are served directly by the eNodeB without the help of the one or more relay nodes, and relay-UEs which are served by the eNodeB and the one or more relay nodes; and adapting link for the macro-UEs and the relay-UEs separately.
