    Abstract: A method and apparatus for code block division are provided. The method may include the following acts. A reference information packet length of a code block is determined according to an obtained division related parameter. A maximum information packet length is determined according to the reference information packet length and a hardware parameter. A Transfer Block (TB) having a length greater than the maximum information packet length may be divided into two or more code blocks according to the obtained division related parameter, the hardware parameter and the determined maximum information packet length. An information length after code block division is less than the determined maximum information packet length.

    Abstract: A data transmission method and device are provided. The method includes: a first transmission node sends data signal(s) for first transmission to a second transmission node, wherein the data signal(s) including data of at least one Transmission Block (TB), the TB including K Code Blocks (CBs), and the K CBs being divided into P CB sets; the first transmission node performs packet coding on M CB sets in the P CB sets to obtain S check CB sets; and the first transmission node generates data signal(s) for retransmission and sends the data signal(s) to the second transmission node, the data signal(s) for retransmission at least including Q bits in the check CB sets when a preset condition is met. The embodiments of the present disclosure may effectively reduce resources for retransmission under the condition of not increasing an amount of feedback information.
