Abstract[English]
Various aspects of the present disclosure relate to managing cross-link interference (CLI) for dynamic sub-band full-duplex (SBFD). For example, the systems and methods utilize sounding reference signal (SRS) enhancements, where a first UE (e.g., an aggressor UE) utilizes parameters of an SRS to indicate an expected or utilized SBFD sub-band. A second UE (e.g., a victim UE) measures the SRS and obtains an SRS-RSRP and information that identifies the sub-band having the expected CLI. The second UE may then report the obtained information to an associated base station, which can perform various CLI management actions, including scheduling, link adaptation, and so on.[French]
Divers aspects de la présente divulgation concernent la gestion d'une interférence de liaison croisée (CLI) pour un duplex intégral de sous-bande (SBFD) dynamique. Par exemple, les systèmes et les procédés utilisent des améliorations de signal de référence de sondage (SRS), un premier UE (par exemple, un UE agresseur) utilisant des paramètres d'un SRS pour indiquer une sous-bande SBFD prévue ou utilisée. Un second UE (par exemple, un UE victime) mesure le SRS et obtient un SRS-RSRP et des informations qui identifient la sous-bande ayant la CLI prévue. Le second UE peut ensuite rapporter les informations obtenues à une station de base associée, qui peut effectuer diverses actions de gestion de CLI, y compris une planification, une adaptation de liaison, etc.
