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."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Method for transmitting signals using HARQ scheme to guarantee constellation rearrangement gain","description":"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.
