Abstract

L'invention concerne un procédé et un dispositif dans un nœud utilisé pour une communication sans fil. Un nœud reçoit d'abord une première signalisation, puis reçoit une signalisation cible ; la signalisation cible comprend un premier champ et un second champ, le premier champ de la signalisation cible est utilisé pour indiquer une quantité de DCI de premier type, et le second champ de la signalisation cible est utilisé pour indiquer une quantité de DCI de second type ; la première signalisation est utilisée pour indiquer que les DCI de premier type comprennent une transmission à base de TB de planification de DCI et que les DCI de second type comprennent une transmission à base de CBG de planification de DCI, ou la première signalisation est utilisée pour indiquer que les DCI de premier type comprennent des DCI de première priorité et les DCI de second type comprennent des DCI de seconde priorité. L'invention indique de manière dynamique le nombre de processus HARQ réellement multiplexés dans des transmissions PDSCH de diverses priorités au moyen d'un DAI, ce qui permet d'optimiser la transmission d'un signal de rétroaction de liaison montante et d'améliorer les performances globales.
