Title
(EN) METHODS AND ALGORITHMS OF DATA MULTIPLEXING AT PHY LAYER
(FR) PROCÉDÉS ET ALGORITHMES DE MULTIPLEXAGE DE DONNÉES AU NIVEAU D'UNE COUCHE PHY
Abstract
(EN) A method, system and apparatus are disclosed for methods and algorithms of data multiplexing at a physical (PHY) layer. In one embodiment, a network node is configured to schedule using a single downlink control information, DCI, message a first transmission with repetition of a first transport block, TB, and a second transmission with repetition of a second TB, the repetitions of the first and second TBs being mapped to non-overlapping time- domain resources and the repetitions of first and second TBs being mapped to a same physical resource block, PRB, set; and trigger the first transmission with repetition of the first TB and the second transmission with repetition of the second TB based on the single DCI scheduling. In one embodiment, a wireless device, WD, is configured to receive the single DCI message; and process the repetitions of the first TB and the repetitions of the second TB based at least in part on the single DCI scheduling.
(FR) Sont divulgués ici un procédé, un système et un appareil pour des procédés et des algorithmes de multiplexage de données au niveau d'une couche physique (PHY). Dans un mode de réalisation, un nœud de réseau est configuré pour planifier à l'aide d'un message d'information de commande de liaison descendante, DCI, unique une première transmission avec répétition d'un premier bloc de transport, TB, et une seconde transmission avec répétition d'un second TB, les répétitions des premier et second TB étant mises en correspondance avec des ressources de domaine temporel non chevauchantes et les répétitions des premier et second TB étant mises en correspondance avec un même ensemble de blocs de ressources physiques, PRB ; et pour déclencher la première transmission avec répétition du premier TB et la seconde transmission avec répétition du second TB sur la base de la planification de DCI unique. Dans un mode de réalisation, un dispositif sans fil, WD, est configuré pour recevoir le message de DCI unique ; et traiter les répétitions du premier TB et les répétitions du second TB sur la base, au moins en partie, de la planification de DCI unique.
