Title:
METHODS AND APPARATUS FOR POLAR ENCODING
Document Type and Number:
WIPO Patent Application WO/2019/047246
Kind Code:
A1
Abstract:
A method to explicitly indicate the version information while still supporting soft combining is disclosed. A polar code encoder maps q bits to q positions of q sub-channels, q is a positive integer; wherein the q bits are used to indicate a version of encoded codeword; map K-q information bits to K-q positions for the K-q information bits, K is an integer, K>q; and perform polar encoding over an input vector (I), comprising the q bits and the K-q information bits, with the length of N, N is an integer, N>=K and scramble with scrambling vector over the polar encoded bits, wherein the scrambling vector is associated to the q sub-channels or the scrambling vector is associated to a special frozen bit which is corresponding to the q sub-channels.
