Title
(EN) REMOTE INTERFERENCE MANAGEMENT REFERENCE SIGNAL TRANSMISSION
(FR) TRANSMISSION DE SIGNAL DE RÉFÉRENCE DE GESTION D'INTERFÉRENCE À DISTANCE
Abstract
(EN)
A method, base station (BS), user equipment (UE), apparatus, and computer program product for wireless communication are provided. An aggressor BS may cause a remote interference condition for a victim BS, and the victim BS may transmit a reference signal to the aggressor BS to enable a remote interference management (RIM) operation to be performed. However, the aggressor BS may be unable to identify the victim BS based at least in part on the reference signal, and may fail to transmit a reference signal as a response. Further, when the aggressor BS does transmit a reference signal, the victim BS may be unable to identify the aggressor BS. This may reduce an effectiveness of RIM operations. In some aspects, BSs may transmit reciprocal reference signals including identification information to enable effective RIM operations.
(FR)
La présente invention concerne un procédé, une station de base (BS), un équipement utilisateur (UE), un appareil et un produit programme d'ordinateur pour une communication sans fil. Une BS agresseuse peut provoquer une condition d'interférence à distance pour une BS victime, et la BS victime peut transmettre un signal de référence à la BS agresseuse pour permettre l'exécution d'une opération de gestion d'interférence à distance (RIM). Cependant, la BS agresseuse peut être incapable d'identifier la BS victime sur la base, au moins en partie, du signal de référence, et peut échouer à transmettre un signal de référence en tant que réponse. En outre, lorsque la BS agresseuse transmet un signal de référence, la BS victime peut être incapable d'identifier la BS agresseuse. Ceci peut réduire l'efficacité des opérations RIM. Selon certains aspects, des BS peuvent transmettre des signaux de référence réciproques comprenant des informations d'identification pour permettre des opérations RIM efficaces.
