Title
(EN) SCHEDULING HARQ TRANSMISSIONS IN MINI-SLOTS BASED ON FADING CONDITIONS
(FR) ORDONNANCEMENT DE TRANSMISSIONS HARQ DANS DES MINI-INTERVALLES BASÉ SUR DES CONDITIONS D'ÉVANOUISSEMENT
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 detecting a fading condition of a device; scheduling, in one or more mini-slots of a PRB, a HARQ transmission based at least in part on the fading condition; and transmitting, to the device, the HARQ transmission in the one or more mini-slots of the PRB.

Des systèmes, des procédés et des dispositifs peuvent être utilisés pour ordonnancer au moins une transmission de demande de répétition automatique hybride (HARQ) et au moins un message de rétroaction de HARQ dans le même bloc de ressources physiques (PRB). Une transmission de HARQ peut être ordonnancée dans un mini-intervalle du PRB. Ainsi, les latences associées à la transmission et à la réception du PRB peuvent être réduites, tandis que la fiabilité élevée de HARQ peut être conservée. Des mises en oeuvre peuvent être appliquées aux technologies 5G, telles que des communications à faible latence ultra-fiables (URLLC) et une large bande mobile améliorée (eMBB), ainsi que d'autres communications à faible latence. Un procédé peut comprendre la détection d'une condition d'évanouissement d'un dispositif ; l'ordonnancement, dans un ou plusieurs mini-intervalles d'un PRB, une transmission HARQ basée sur au moins en partie, la condition d'évanouissement ; et la transmission, au dispositif, de la transmission HARQ dans le ou les mini-intervalles du PRB.
