Abstract

L'invention concerne un appareil et un procédé de transmission de canal partagé de liaison montante physique (PUSCH). L'invention concerne un procédé de transmission de canal PUSCH d'un équipement utilisateur (UE) qui consiste à déterminer une première transmission de canal PUSCH correspondant à un premier bloc de transport (TB) d'un numéro de processus de demande de répétition automatique hybride (HARQ) qui doit être transmis, et à déterminer une seconde transmission de canal PUSCH correspondant à un second TB du numéro de processus de demande HARQ qui doit être transmis, la seconde transmission de canal PUSCH étant réalisée pour être au moins un intervalle de temps après la première transmission de canal PUSCH. Ceci peut augmenter un débit de transmission qui peut résoudre un goulot d'étranglement en raison d'un long temps aller-retour, et/ou offrir une bonne performance de communication et une fiabilité élevée.
