Abstract: Certains modes de réalisation comprennent un appareil, un procédé et un produit-programme d'ordinateur pour faciliter des temps de traitement dans un système de communications sans fil 5G. Lors du fonctionnement à un espacement de sous-porteuse (SCS) de fréquence supérieure, des temps de créneau pour recevoir et/ou transmettre des données entre un équipement utilisateur (UE) et un nœud B 5G (gNB) deviennent plus courts. En raison de cela, certains UE peuvent faire face à la difficulté de traiter les données de canal partagé en liaison descendante physique (PDSCH), de canal partagé en liaison montante physique (PUSCH) et/ou de canal de commande en liaison descendante physique (PDCCH) avec une vitesse suffisante. Pour résoudre des limitations potentielles, un temps de traitement minimal flexible peut être utilisé pour s'adapter à différentes capacités de traitement d'UE. L'UE peut rapporter ses capacités de traitement au gNB. Le gNB peut ensuite programmer des communications en fonction des capacités de traitement de l'UE. Le gNB peut tenir compte du fait que l'UE mette en œuvre un seul ou plusieurs moteurs de traitement. En outre, le gNB peut appliquer des techniques de planification à créneau unique et/ou à créneaux multiples pour empêcher également des problèmes de synchronisation.
