Abstract:
(EN) The present invention relates to a 5th generation (5G) or pre-5G communication system for supporting a higher data transmission rate than a 4th generation (4G) communication system such as Long Term Evolution (LTE). An operation method of a receiver in a communication system comprises the steps of: receiving an encoded bit string corresponding to message bits and first cyclic redundancy check (CRC) bits; obtaining a codeword through a traceback of at least a part of the encoded bit string; generating second CRC bits by performing a CRC encoding of the obtained codeword; and performing a decoding on the basis of at least a part of the second CRC bits.
(FR) La présente invention concerne un système de communication de 5e génération (5G) ou pré-5G destiné à prendre en charge un débit de transmission de données plus élevé que celui d'un système de communication de 4e génération (4G), tel qu'un système d'évolution à long terme (LTE). Un procédé de fonctionnement d'un récepteur dans un système de communication comprend les étapes suivantes consistant : à recevoir une chaîne de bits codée correspondant à des bits de message et des premiers bits de contrôle de redondance cyclique (CRC); à obtenir un mot de code par l'intermédiaire d'un retraçage d'au moins une partie de la chaîne de bits codée; à générer des seconds bits CRC par réalisation d'un codage CRC du mot de code obtenu; et à effectuer un décodage sur la base d'au moins une partie des seconds bits CRC.
(KO) 본 개시는 LTE(Long Term Evolution)와 같은 4G(4th generation) 통신 시스템 이후 보다 높은 데이터 전송률을 지원하기 위한 5G(5th generation) 또는 pre-5G 통신 시스템에 관련된 것이다. 통신 시스템에서 수신단의 동작 방법은, 메시지 비트들 및 제1 CRC(cyclic redundancy check) 비트들에 대응하는 부호화된 비트열을 수신하는 과정과, 상기 부호화된 비트열의 적어도 일부에 대한 트레이스백을 통해 부호어를 획득하는 과정과, 상기 획득한 부호어에 대한 CRC 부호화를 수행함으로써 제2 CRC 비트들을 생성하는 과정과, 상기 제2 CRC 비트들 중 적어도 일부에 기반하여 복호를 수행하는 과정을 포함한다.
