Method and apparatus for processing data

摘要

Embodiments of the present invention provide a method and an apparatus for processing data. The method includes: performing code block segmentation on a data block to obtain multiple first blocks, wherein a difference between numbers of bits of any two first blocks in the multiple first blocks is not more than 1 bit; determining multiple second blocks according to a padding bit and the multiple first blocks, wherein a value of the padding bit is a preset value; adding consecutive N−K fixed bits to each of the multiple second blocks to obtain multiple third blocks, wherein a value of the fixed bit is a preset value, and N−K≧0; and performing polar encoding according to the multiple third blocks.

1. A method for processing data, comprising:
performing code block segmentation on a data block to obtain multiple first blocks, wherein a difference between numbers of bits of any two first blocks block is not more than 1 bit; determining multiple second blocks according to at least one padding bit and the multiple first blocks, wherein a quantity of bits of each of the multiple second blocks is K, K is a quantity of information bits of a polar code, and a value of each padding bit is a preset value; adding consecutive N−K fixed bits to each of the multiple second blocks to obtain multiple third blocks, wherein a value of each fixed bit is a preset value, a value of N is 2^n, n is an integer larger than 0, and N−K≧0; and performing polar encoding according to the multiple third blocks.
