Title:
METHODS AND APPARATUS FOR CRC CONCATENATED POLAR ENCODING
Document Type and Number:
WIPO Patent Application WO/2019/090468
Kind Code:
A1
Abstract:
Certain aspects of the present disclosure generally relate to techniques for encoding information bits using cyclic redundancy check (CRC) concatenated polar encoding. The CRC concatenated polar encoding techniques may avoid transmission of dummy bits. A method generally includes obtaining the bits of information to be transmitted. The method includes performing CRC outer encoding of the information bits using an even-weighted generator polynomial to produce CRC encoded bits. The method includes performing polar inner encoding of the CRC encoded bits to generate a codeword. The method includes discarding a first code bit at a beginning of the codeword. The codeword is transmitted over a wireless medium. In another method, bit-level scrambling is performed on the CRC encoded bits before the polar encoding.
