    摘要: A method for modifying a synchronous non- adaptive retransmission scheme to solve the limitation of the synchronous non-adaptive retransmission scheme is disclosed. A method for indicating not only the new data transmission but also the retransmission using a data scheduling message is disclosed. A method for determining whether there is an error in the ACK signal transmitted from a data reception end using another message to -be received later is disclosed. The retransmission method for a multi-carrier system includes: receiving a grant message including scheduling information for transmitting uplink data wherein a retransmission scheme for the uplink data is predetermined by a first retransmission scheduling, transmitting the uplink data according to the scheduling information and retransmitting the uplink data according to second retransmission scheduling by receiving the second retransmission scheduling information associated with the uplink data with retransmission request.

    摘要: A method and apparatus for recovering a backhaul link failure between a base station and a relay node is provided. The relay node receives information on a plurality of relay subframes used for relaying signals between the base station and the relay node. When a backhaul link failure is detected, the relay node determines at least one reserved subframe except the plurality of relay subframes and receives information to recover the backhaul link failure on a control channel in the at least one reserved subframe.

    摘要: A method for transmitting signals using a hybrid automatic repeat request (HARQ) scheme to guarantee a constellation rearrangement gain having a predetermined level or more is provided. Predetermined code blocks are encoded, sub-block interleaving is performed with respect to the encoded code blocks, and the sub-block interleaved code blocks are transmitted according to redundancy version (RV) start locations of the sub-block interleaved code blocks. The RVs are set such that the order of bit streams modulated by an M-QAM (M>4) scheme is changed upon a retransmission. In addition, the RVs are set such that the RV start locations applied to code blocks having different sizes are different.
