摘要： A data retransmission method for a polar code, and a device therefor are disclosed. The data retransmission method of the disclosure can comprise the steps of: generating a first data block by allocating a plurality of data bits to input bits, with high priorities, among input bits of a polar code encoding module on the basis of a target encoding rate; transmitting the generated first data block; generating a second data block by allocating first data bits among the plurality of data bits to input bits, with low priorities, among the input bits of the polar code encoding module, on the basis of the target encoding rate and shortening bits; and transmitting the generated second data block as a retransmission of the first data block.

摘要： Disclosed are a method for dividing a carrying block of a Low Density Parity Check (LDPC) code and an apparatus therefor. The method for dividing a LDPC code of the present disclosure can obtain a high throughput by using a limited size of shifting network. Moreover, it is possible to prevent degradation in performance due to a minimum size of code block by performing shortening for a large size of code block while minimizing the number of code blocks. Furthermore, in selection of a minimum size of code block, since a minimum size of code block is selected on the basis of shortening for a relatively large size of code block, it is possible to increase the size of the minimum size of code block.
