摘要： Disclosed is a method and an apparatus for efficient ACKnowledgment/NonACKnowledgement (ACK/NACK) transmission in order to transmit forward data for multiple layers and support Hybrid Automatic Retransmission reQuest (HARQ) for each layer in a mobile communication system. The method includes determining whether transmission of the ACK/NACK is for a first layer or for layers higher than the first layer; and when the transmission of the ACK/NACK is for layers higher than the first layer, transmitting the reverse ACK/NACK by allocating resources to the higher layers with a quantity different from that of the first layer.
