Title:
TECHNIQUES AND APPARATUSES FOR CODEWORD BIT SELECTION FOR RATE-COMPATIBLE POLAR CODING
Document Type and Number:
WIPO Patent Application WO/2019/191923
Kind Code:
A1
Abstract:
Various aspects of the present disclosure generally relate to wireless communication. In some aspects, an encoding device may determine a least reliable subset of information bits included in a set of information bits that includes a predefined active set of information bits to be encoded; may determine a codeword bit to be added to a codeword based at least in part on the least reliable subset of information bits, wherein adding the codeword bit to the codeword improves reliability of the least reliable subset of information bits; may add the codeword bit to the codeword; and may transmit the codeword. Numerous other aspects are provided.
