Title
(EN) REFERENCE SIGNALING FOR NEIGHBOR INTERFERENCE MANAGEMENT
(FR) SIGNALISATION DE RÉFÉRENCE POUR GESTION D'INTERFÉRENCES VOISINES
Abstract
(EN)
Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a first base station may communicate a reference signal for interference management between the first base station and a second base station, wherein respective time division duplexing configurations of the first base station and the second base station conflict with each other; and perform an interference management operation based at least in part on the reference signal. Numerous other aspects are provided.
(FR)
Selon divers aspects, l'invention se rapporte d'une manière générale à la communication sans fil. Selon certains aspects, une première station de base peut : communiquer un signal de référence pour une gestion d'interférences entre la première station de base et une seconde station de base, les configurations de duplexage par répartition dans le temps respectives de la première station de base et de la seconde station de base étant en conflit l'une avec l'autre ; et effectuer une opération de gestion d'interférences d’après au moins en partie le signal de référence. L'invention se présente également sous de nombreux autres aspects.
