Title (EN) UPLINK ALLOCATION ECHOING BY A UE AT THE CELL EDGE FOR INTERFERENCE COORDINATION
(FR) RENVOI EN ÉCHO D'ATTRIBUTION DE LIAISON MONTANTE PAR UN UE AU NIVEAU DU BORD DE CELLULE POUR COORDINATION D'INTERFÉRENCE
Abstract:
(EN) Interference coordination using over the air data is enabled. A UE receives downlink control information including uplink resource allocation. The UE determines whether it is near a cell edge of its serving cell. If so, the UE echoes at least a subset of the allocation information over the air to one or more neighboring base stations. The echo may use a multi-cluster PUSCH approach or a combined PUSCH, PUCCH approach. One or more neighboring base stations receive the echoed allocation data. With the echoed data, the neighboring base stations engage in interference coordination, thereby avoiding delays inherent in non-idea backhaul connections. Other aspects, embodiments, and features are also claimed and described.
(FR) Une coordination d'interférence est activée à l'aide de données radio. Un UE reçoit des informations de commande de liaison descendante comprenant une attribution de ressource de liaison montante. L'UE détermine s'il se trouve ou pas à proximité d'un bord de cellule de sa cellule de desserte. Si tel est le cas, l'UE renvoie en écho au moins un sous-ensemble des informations d'attribution par radio vers une ou plusieurs stations de base voisines. L'écho peut utiliser une approche à canal PUSCH multi-grappe ou une approche à canal PUCCH, PUSCH combiné. Une ou plusieurs stations de base voisines reçoivent les données d'attribution renvoyées en écho. À l'aide des données renvoyées en écho, les stations de base voisines participent à la coordination d'interférence, évitant ainsi les retards inhérents aux connexions terrestres qui ne sont pas idéales. La présente invention concerne également d'autres aspects, modes de réalisation et caractéristiques.
