Title (EN) METHOD OF INFORMING SERVING CELL OF UPLINK INTERFERENCE AT NEIGHBOR CELL CAUSED BY UNMANNED AERIAL VEHICLE
(FR) PROCÉDÉ D'INFORMATION DE CELLULE DE DESSERTE D'INTERFÉRENCE DE LIAISON MONTANTE AU NIVEAU D'UNE CELLULE VOISINE, PROVOQUÉE PAR UN VÉHICULE AÉRIEN SANS PILOTE
Abstract:
(EN) A neighboring cell determines that uplink interference from an unmanned aerial vehicle (UAV) exceeds a first threshold at the neighboring cell. The neighboring cell transmits an uplink interference indicator to the UAV. In some examples, the UAV informs its serving cell of the uplink interference experienced by the neighboring cell. The serving cell can utilize information received from the UAV to make handover decisions or scheduling decisions for the UAV that caused the uplink interference. In other examples, the UAV can temporarily refrain from transmitting on at least some of its uplink resources or utilize different uplink resources for uplink data transmissions. In still other examples, the UAV can utilize downlink measurements to select which neighboring base station System Information Block messages should be monitored for an uplink interference indicator.
(FR) Selon l'invention, une cellule voisine détermine qu'une interférence de liaison montante provenant d'un véhicule aérien sans pilote (UAV) dépasse un premier seuil au niveau de la cellule voisine. La cellule voisine transmet un indicateur d'interférence de liaison montante à l'UAV. Dans certains exemples, l'UAV informe sa cellule de desserte de l'interférence de liaison montante subie par la cellule voisine. La cellule de desserte peut utiliser des informations reçues de l'UAV pour prendre des décisions de transfert intercellulaire ou d'ordonnancement pour l'UAV ayant provoqué l'interférence de liaison montante. Dans d'autres exemples, l'UAV peut s'abstenir temporairement de transmettre sur au moins certaines de ses ressources de liaison montante ou utiliser différentes ressources de liaison montante pour des transmissions de données de liaison montante. Dans d'autres exemples encore, l'UAV peut utiliser des mesures de liaison descendante pour sélectionner les messages de bloc d'informations système de station de base voisine qui doivent être surveillés pour un indicateur d'interférence de liaison montante.
