Abstract:
(EN) This disclosure relates to a 5G or pre-5G communication system for supporting a higher data transfer rate than a 4G communication system such as LTE. The present invention relates to a method for encoding and decoding a channel in a communication or broadcasting system, comprising the steps of: determining an input bit size (CBS); determining a code rate (R); determining a size (Z) of a block; comparing the determined CBS and code rate with predetermined reference values; determining an LDPC sequence to perform LDPC encoding according to the comparison result; and performing LDPC encoding and decoding on the basis of the LDPC sequence and the block size. Further, the present invention comprises the steps of: determining a code rate (R) indicated by a modulation and coding scheme (MCS) index; determining a transport block size; and determining either a first basic matrix or a second basic matrix as a basic matrix on the basis of the transport block size and the code rate.
(FR) La présente invention se rapporte à un système de communication 5G ou pré-5G permettant de prendre en charge un débit de transfert de données supérieur à celui d'un système de communication 4G, tel qu'un système LTE. La présente invention concerne un procédé de codage et de décodage d'un canal dans un système de communication ou de diffusion consistant : à déterminer une taille de bit d'entrée (CBS) ; à déterminer un débit de code (R) ; à déterminer une taille (Z) d'un bloc ; à comparer la CBS déterminée et le débit de code avec des valeurs de référence prédéterminées ; à déterminer une séquence LDPC afin d'effectuer un codage LDPC en fonction du résultat de la comparaison ; et à réaliser un codage et un décodage LDPC en fonction de la séquence LDPC et de la taille de bloc. En outre, la présente invention consiste : à déterminer un débit de code (R) indiqué par un indice de mécanisme de modulation et de codage (MCS) ; à déterminer une taille de bloc de transport ; et à déterminer une première matrice de base ou une seconde matrice de base en tant que matrice de base en fonction de la taille de bloc de transport et du débit de code.
(KO) 본 개시는 LTE와 같은 4G 통신 시스템 이후 보다 높은 데이터 전송률을 지원하기 위한 5G 또는 pre-5G 통신 시스템에 관련된 것이다. 본 발명은 통신 또는 방송 시스템에서 채널 부호화 및 복호화 방법에 있어서, 입력 비트 크기(CBS)를 결정하는 과정; 부호율(R)을 결정하는 과정; 블록의 크기(Z)를 결정하는 과정; 상기 결정된 CBS 및 부호율과 사전에 결정된 기준 값들과 비교하는 과정; 상기 비교 결과에 따라 LDPC 부호화를 수행할 LDPC 수열을 결정하는 과정; 상기 LDPC 수열과 블록 크기에 기반하여 LDPC 부호화 및 복호화 하는 과정; 을 포함함을 특징으로 한다. 또한, 본 발명은 모듈레이션 및 코딩 스킴 (modulation and coding scheme: MCS) 인덱스에 의해 지시되는 부호율 (R)을 결정하는 단계; 전송 블록 크기 (transport block size)를 결정하는 단계; 상기 전송 블록 크기 및 상기 부호율에 기반하여 제1 기본 행렬 또는 제2 기본 행렬 중 어느 하나를 기본 행렬로 결정하는 단계를 포함하는 것을 특징으로 한다.
