Title (EN) SYSTEMS AND METHODS FOR DISTRIBUTED OPEN-LOOP MULTI-USER CO-OPERATIVE MULTI-POINT (CoMP) SCHEDULING AND TRANSMISSION
(FR) SYSTÈMES ET PROCÉDÉS POUR UNE PROGRAMMATION ET UNE TRANSMISSION MULTIPOINT COLLABORATIVE MULTI-UTILISATEUR (MU-COMP) À BOUCLE OUVERTE DISTRIBUÉE
Abstract:
(EN) Embodiments are provided to enable distributed open-loop multi-user co-operative multi-point (MU-CoMP) scheduling and transmission. In an embodiment, network nodes schedule data transmissions for UEs among multiple transmission tiers that include a first transmission tier having predetermined modulation and coding and a second transmission tier having adaptive modulation and coding. The first transmission tier and the second transmission tier are in respective time-frequency resources that at least partially overlap. The network nodes transmit the scheduled data transmissions in the transmission tiers according to the scheduling for the UEs. A UE receives CoMP transmissions once it is scheduled for transmission by multiple network nodes.
(FR) Des modes de réalisation de l'invention permettent d'exécuter une programmation et une transmission multipoint collaborative multi-utilisateur (MU-CoMP) à boucle ouverte distribuée. Dans un mode de réalisation, des nœuds de réseau programment des transmissions de données pour des UE parmi une pluralité de niveaux de transmission qui comprennent un premier niveau de transmission ayant une modulation et un codage prédéterminés et un second niveau de transmission ayant une modulation et un codage adaptatifs. Le premier niveau de transmission et le second niveau de transmission se trouvent dans des ressources temps-fréquence respectives qui se chevauchent au moins partiellement. Les nœuds de réseau transmettent les transmissions de données programmées dans les niveaux de transmission selon la programmation des UE. Un UE reçoit des transmissions CoMP une fois qu'il est programmé pour une transmission par une pluralité de nœuds de réseau.
