Title
(EN) SCHEDULING HARQ TRANSMISSIONS IN MINI-SLOTS
(FR) PLANIFICATION DE TRANSMISSIONS HARQ DANS DES MINI-CRÉNEAUX
Abstract
(EN)
Systems, methods, and devices can be utilized to schedule at least one Hybrid Automatic Repeat Request (HARQ) transmission and at least one HARQ feedback message in the same Physical Resource Block (PRB). A HARQ transmission can be scheduled in a mini-slot of the PRB. Accordingly, latencies associated with transmitting and receiving the PRB can be reduced, while the high reliability of HARQ can be retained. Implementations can be applied to 5G technologies such as Ultra Reliable Low Latency Communications (URLLCs) and enhanced Mobile BroadBand (eMBB), as well as other low-latency communications. A method can include determining a location of a device; selecting, based at least in part on the location of the device, a mini-slot size; scheduling, in one or more mini-slots having the mini-slot size in a PRB, a HARQ transmission; and transmitting, to the device, the HARQ transmission in the one or more mini-slots of the PRB.

La présente invention concerne des systèmes, des procédés et des dispositifs qui peuvent être utilisés pour ordonnancer au moins une transmission de demande de répétition automatique hybride (HARQ) et au moins un message de retour HARQ dans le même bloc de ressources physiques (PRB). Une transmission HARQ peut être ordonnancée dans un mini-créneau du PRB. Par conséquent, les latences associées à la transmission et à la réception du PRB peuvent être réduites tout en conservant la fiabilité élevée de l’HARQ. Des mises en œuvre peuvent être appliquées à des technologies 5G telles que les communications à faible latence ultra-fiables (URLLC) et la large bande mobile améliorée (eMBB), ainsi qu'à d'autres communications à faible latence. Un procédé peut comprendre la détermination d'un emplacement d'un dispositif ; la sélection, sur la base, au moins en partie, de l'emplacement du dispositif, d'une taille de mini-créneau ; l'ordonnancement, dans un ou plusieurs mini-créneaux ayant la taille de mini-créneau dans un PRB, d'une transmission HARQ ; et la transmission au dispositif, de la transmission HARQ dans le mini-créneau ou les mini-créneaux du PRB.
