Title (EN) INTERFERENCE MITIGATION FOR AERIAL VEHICLE COMMUNICATIONS BY SHARING SCHEDULING INFORMATION WITH NEIGHBORING BASE STATIONS
(FR) ATTÉNUATION DES INTERFÉRENCES POUR COMMUNICATIONS DE VÉHICULE AÉRIEN PAR PARTAGE D'INFORMATIONS DE PLANIFICATION AVEC DES STATIONS DE BASE VOISINES
Abstract:
(EN) A serving base station allocates communication resources to be used by an aerial vehicle user equipment device (AV-UE) for uplink data transmissions. A neighboring base station is informed, via an air interface, of the communication resources that were allocated to the AV-UE. In some examples, the AV-UE retransmits scheduling assignment information, received from the serving base station, to the neighboring base station. In still other examples, the AV-UE transmits a sounding reference signal (SRS) to the neighboring base station. The neighboring base station can decode the retransmitted scheduling assignment information and/or the SRS to obtain information regarding the communication resources that have been allocated to the AV-UE for uplink data transmissions. The neighboring base station mitigates interference from the uplink data transmissions sent by the AV-UE.
(FR) Station de base de desserte attribuant des ressources de communication à utiliser par un dispositif d'équipement utilisateur de véhicule aérien (AV-UE) pour des transmissions de données de liaison montante. Une station de base voisine est informée, par l'intermédiaire d'une interface sans fil, des ressources de communication qui ont été attribuées à l'AV- UE. Dans certains exemples, l'AV-UE retransmet des informations d'attribution de planification, reçues à partir de la station de base de desserte, à la station de base voisine. Dans d'autres exemples, l'AV-UE transmet un signal de référence de sondage (SRS) à la station de base voisine. La station de base voisine peut décoder les informations d'attribution de planification retransmises et/ ou le SRS pour obtenir des informations concernant les ressources de communication qui ont été attribuées à l'AV-UE pour des transmissions de données de liaison montante. La station de base voisine atténue les interférences des transmissions de données de liaison montante envoyées par l'AV-UE.
