Title
(EN) HARQ HANDLING FOR SINGLE-DCI MULTI-SLOT SCHEDULING
(FR) GESTION DE HARQ POUR LA PLANIFICATION À MULTIPLES CRÉNEAUX D'UNE SEULE DCI
Abstract
(EN)
A network node causes transmission of DCI that includes information for scheduling two or more TBs over two or more communication slots. The two or more TBs are associated with two or more HARQ process IDs. The information includes one or more of: a PUCCH resource indicator configured to indicate at least one 5 resource for use for transmitting HARQ feedback related to the two or more TBs; a DAI configured to indicate a position of HARQ feedback related to the two or more TBs, in a HARQ codebook; a HARQ process ID indicator indicating two or more HARQ process IDs; and one or more NDIs configured to indicate whether at least one of the two or more TBs is a retransmission.
(FR)
Un nœud de réseau provoque la transmission d'une DCI qui comprend une information pour planifier deux TB ou plus par le biais de deux créneaux de communication ou plus. Les deux TB ou plus sont associés à deux ID de processus de HARQ ou plus. L'information comprend un ou plusieurs de ce qui suit : un indicateur de ressource de PUCCH configuré pour indiquer au moins une ressource à utiliser pour transmettre une information en retour de HARQ concernant les deux TB ou plus; un DAI configuré pour indiquer une position de l'information en retour de HARQ concernant les deux TB ou plus, dans un livre de codes de HARQ; un indicateur ID de processus HARQ indiquant deux ID de processus HARQ ou plus; et un ou plusieurs NDI configurés pour indiquer si au moins un des deux TB ou plus est une retransmission.
