A method and device for data transmission. The method comprises: the first transmission node transmits to a second transmission node a data signal being transmitted for the first time, where the data signal comprises data of at least one transmission block, the transmission block comprises a K-number of code blocks, the K-number of code blocks are divided into a P-number of code block sets; the first transmission node performs packed encoding on an M-number of code block sets among the P-number of code block sets to produce an S-number of check-code block sets; the first transmission node generates a retransmission data signal and transmits to the second transmission node; and, when a predetermined condition is satisfied, the retransmission data signal comprises at least a Q-number of bits in the check-code block sets. Embodiments of the present invention are capable of effectively reducing resources used by retransmission without increasing the amount of feedback information. |
