Abstract
(EN)
Aspects of this disclosure relate to an improved coordinated multipoint (CoMP) network operating in a millimeter wave frequency band in which user equipment (UEs) combine signals received across multiple spatial beams from multiple base stations. The improved CoMP network can achieve high throughput, low latency, and/or high reliability at millimeter wave frequencies while maintaining a reasonable network complexity (e.g., lower network overhead than CoMP networks implemented with coherent combining). For example, the improved CoMP network can include one or more base stations and one or more UEs. Multiple base stations can transmit the same data across multiple spatial beams to a UE at the same time. The base stations may use information provided by a UE to identify an active set of base stations and/or spatial beams to serve the UE.

Selon certains aspects, la présente invention concerne un réseau multipoint coordonné (CoMP) amélioré fonctionnant dans une bande de fréquence d'ondes millimétriques dans laquelle des équipements utilisateurs (UE) combinent des signaux reçus à travers de multiples faisceaux spatiaux provenant de multiples stations de base. Le réseau CoMP amélioré peut atteindre un débit élevé, une faible latence, et/ou une fiabilité élevée à des fréquences d'ondes millimétriques tout en maintenant une complexité de réseau raisonnable (par exemple, un surdébit de réseau inférieur à celui des réseaux CoMP mis en oeuvre avec une combinaison cohérente). Par exemple, le réseau CoMP amélioré peut comprendre une ou plusieurs stations de base et un ou plusieurs UE. De multiples stations de base peuvent transmettre les mêmes données à travers de multiples faisceaux spatiaux à un UE en même temps. Les stations de base peuvent utiliser des informations fournies par un UE pour identifier un ensemble actif de stations de base et/ou de faisceaux spatiaux afin de desservir l'UE.
