Title (EN) CRC AIDED POLAR CODING WITH AVOIDANCE OF CIRCULAR INVARIANCE OF POLAR CODEWORD FOR IMPLICIT SIGNALING BY CIRCULAR SHIFTING
(FR) CODAGE POLAIRE ASSISTÉ PAR UN CONTRÔLE CRC AYANT UN ÉVITEMENT D'INVARIANCE CIRCULAIRE D'UN MOT CODÉ POLAIRE POUR UNE SIGNALISATION IMPLICITE PAR UN DÉPLACEMENT CIRCULAIRE
Abstract:
(EN) Certain aspects of the present disclosure provide techniques for an improved encoder for reducing repetition in polar codewords. An apparatus for wireless communication is provided. The apparatus includes at least one processor. The at least one processor is coupled with a memory. The at least one processor includes at least one encoder circuit configured to encode a set of information bits based on a cyclic redundancy check (CRC)-aided polar code to produce a codeword including polar encoded information bits and CRC bits. The at least one encoder circuit is configured to place one or more of the CRC bits at a start of the codeword and to set a value of the one or more CRC bits to a non-zero value. The apparatus includes a transmitter configured to transmit the codeword in accordance with a wireless technology across a channel via one or more antenna elements situated proximate the transmitter.
(FR) La présente invention porte, selon certains aspects, sur des techniques pour un codeur amélioré permettant de réduire la répétition dans des mots codés polaires. La présente invention se rapporte à un appareil de communication sans fil. L'appareil comprend au moins un processeur. Le ou les processeurs sont couplés à une mémoire. Le ou les processeurs comprennent au moins un circuit codeur configuré de sorte à coder un ensemble de bits d'information sur la base d'un code polaire assisté par un contrôle de redondance cyclique (CRC) pour produire un mot codé comprenant des bits d'information codés polaires et des bits de contrôle CRC. Le ou les circuits de codeur sont configurés de sorte à placer un ou plusieurs des bits de contrôle CRC au début du mot codé et à fixer une valeur du ou des bits de contrôle CRC à une valeur non nulle. Un appareil comprend un émetteur configuré de sorte à transmettre le mot codé en fonction d'une technologie sans fil à travers un canal sans fil par le biais d'un ou de plusieurs éléments d'antenne situés à proximité de l'émetteur.
