Abstract

Selon certains modes de réalisation, un procédé destiné à être utilisé dans un émetteur sans fil de codage d'un bloc de transport consiste à sélectionner, quand il est déterminé qu'un débit de code de transmission d'un bloc de transport est inférieur ou égal à r_seuil (r_seuil est compris entre 1/5 et 1/3), un graphe de base (2) de contrôle de parité à faible densité (ldcp) de nouvelle radio (nr) de manière à coder le bloc de transport. Par ailleurs, le procédé consiste à sélectionner un graphe de base (1) ldpc nr de manière à coder le bloc de transport, sauf si une taille de bloc de transport (tbs) du bloc de transport est inférieure ou égale à un seuil de taille (x) et un débit de code de transmission du bloc de transport est inférieur ou égal à 2/3, auquel cas le procédé peut consister à sélectionner un graphe de base (2). Le procédé consiste en outre à coder le bloc de transport à l'aide du graphe de base sélectionné et à transmettre le bloc de transport codé à un récepteur sans fil.
