Abstract: Facing the penetration of immersive communication services into multiple industries and the deep integration of sensing, communication, computation, and artificial intelligence, 6G networks are confronted with numerous technical challenges. To address these issues, a novel 6G quality of service (QoS) architecture and a series of key technologies are proposed. These include the adoption of packet-level fine-grained QoS control and the definition of a new QoS type that guarantees bit rates without resource reservation, so as to enhance user equipment uplink rates and enable fast dynamic QoS regulation on the user plane. Leveraging 6G endogenous intelligence, traffic detection and QoS parameter generation are realized, and collaboration and synchronization schemes for multi-modal streams are developed. An intention-aware and traffic-adaptive transmission scheme is designed to support avatar-enabled intelligent agent communication. Furthermore, computational and network resources are coordinated to alleviate the computational bottlenecks of Artificial Intelligence Generated Content (AIGC) and meet the performance requirements of immersive generative communication. Based on the aforementioned technologies, a 6G holographic immersive communication service verification platform is innovatively constructed, achieving a holographic experience where virtual and real worlds coexist, and validating the effectiveness of AI-enabled QoS. While delivering ultra-immersive experiences, a novel video communication space that protects personal privacy is created through the use of intelligent avatars, laying a technical foundation for cultivating new scenarios in future mobile communications.
