Title:
CODING METHOD AND CODING APPARATUS FOR POLAR CODE
Document Type and Number:
WIPO Patent Application WO/2019/052581
Kind Code:
A1
Abstract:
Disclosed in the present invention are a coding method and a coding apparatus for a polar code. The method comprises: determining that a valid payload of broadcast signaling comprises D cyclic redundancy check (CRC) bits and M predictable information bits; respectively mapping the M predictable information bits to M information bits having low reliability among K information bits of a polar code, and mapping the D cyclic redundancy check (CRC) bits to D information bits having high reliability among remaining information bits in the K information bits, so as to obtain mapped bits, M
