Title:
APPARATUS AND METHODS FOR POLAR CODE CONSTRUCTION AND BIT POSITION ALLOCATION
Document Type and Number:
WIPO Patent Application WO/2019/141199
Kind Code:
A1
Abstract:
A sub-channel to carry an information bit, in input bits that are to be encoded, is selected from each of multiple subsets of sub-channels that are provided by a length N polar code. The subsets include sub-channels that are associated with respective overlapping constituent polar codes of the length N polar code. The constituent polar codes are of length N ref < N. An ordered sequence of length N ref, instead of a longer ordered sequence of length N, may be used in selecting the sub-channels. The input bits are encoded to generate a codeword, and the codeword is transmitted.
