Title (EN) METHODS, SYSTEMS AND APPARATUS FOR SCHEDULING OF SUBFRAMES AND HYBRID AUTOMATIC REPEAT REQUEST (HARQ) FEEDBACK
(FR) PROCÉDÉS, SYSTÈMES ET APPAREIL DE PROGRAMMATION DE SOUS-TRAMES ET DE RÉTROACTION DE DEMANDE DE RÉPÉTITION AUTOMATIQUE HYBRIDE (HARQ)
Abstract:
(EN) Methods, systems and apparatus are provided for hybrid automatic repeat request (HARQ) processes for different transmission time interval (TTI) lengths. A wireless transmit/receive unit (WTRU) may link a first HARQ process and a second HARQ process. The WTRU may transmit a first transport block (TB) using the linked first HARQ process and a first HARQ buffer. The WTRU may receive a uplink (UL) grant and determine that the received UL grant is for a new transmission for the linked second HARQ process. The WTRU may release the first HARQ buffer based on a determination that the received UL grant is for the new transmission for the linked second HARQ process. Also, the WTRU may generate a second TB for the new transmission and store the new TB in the first HARQ buffer. The WTRU may transmit the second TB using the linked second HARQ process and the first HARQ buffer.
(FR) L'invention concerne des procédés, des systèmes et un appareil pour des processus de demande de répétition automatique hybride (HARQ) pour différentes longueurs d'intervalles de temps de transmission (TTI). Une unité d'émission/réception sans fil (WTRU) peut relier un premier processus HARQ et un second processus HARQ. La WTRU peut transmettre un premier bloc de transport (TB) en utilisant le premier processus HARQ lié et un premier tampon HARQ. La WTRU peut recevoir une autorisation de liaison montante (UL) et déterminer que l'autorisation UL reçue est destinée à une nouvelle transmission pour le second processus HARQ lié. La WTRU peut libérer le premier tampon HARQ sur la base d'une détermination que l'autorisation UL reçue est destinée à la nouvelle transmission pour le second processus HARQ lié. De plus, la WTRU peut générer un second TB pour la nouvelle transmission et stocker le nouveau TB dans le premier tampon HARQ. La WTRU peut transmettre le second TB en utilisant le second processus HARQ lié et le premier tampon HARQ.
