Pour tous les PDSCH suivants, dans le premier groupe de PDSCH, qui ne chevauchent pas les symboles dans le premier ensemble de symboles, des numéros de processus HARQ correspondants sont séquentiellement augmentés de 1 selon une séquence de planification, et une opération modulo pour une première valeur numérique est utilisée, la première valeur numérique représentant une valeur numérique configurable ou une valeur numérique constante. Le premier ensemble de symboles comprend un symbole indiqué en tant que liaison montante par le second bloc d'informations et au moins un symbole dans la première ressource.
