Title:
POLAR CODE ENCODING METHOD AND APPARATUS
Document Type and Number:
WIPO Patent Application WO/2018/040822
Kind Code:
A1
Abstract:
Provided are a polar code encoding method and apparatus. The method comprises: according to a target code length corresponding to an information bit sequence, determining a first mother code length corresponding to the information bit sequence; and according to the first mother code length and mapping relationship information, performing polar code encoding on the information bit sequence, wherein the mapping relationship information comprises a correlation between a mother code length and at least one of the following: a transport block size, a construction work point and a construction sequence. According to the method provided in the embodiments of the present invention, polar code encoding can be performed on an information bit sequence directly according to at least one of a first transport block size, a first construction work point and a first construction sequence, which correspond to the information bit sequence and are determined based on a mother code length of a polar code, so that encoding overheads in a polar code encoding process can be reduced.
