The European research project 5G-Xcast (Broadcast and Multicast Communication Enabler of the 5th mobile radio generation) develops, evaluates and demonstrates a conceptually novel and future-oriented 5G network architecture in which unicast, multicast, broadcast and local caching can be used as transmission modes. In addition to solutions for freely accessible linear media distribution (e.g. live TV services), public security and the Internet of Things, a dynamically adaptable 5G network architecture with layer-independent network interfaces for dynamic and seamless switching between unicast, multicast and broadcast modes will be developed.
One of the main objectives of 5G-Xcast is to demonstrate the feasibility of the main technological innovations of the project for the monitoring & evaluation sector. IRT's role is to ensure that the 5G ecosystem can be configured to support traditional and new media services. For this purpose, appropriate network interfaces to content service providers, the required callflows within the core network and air interface and framing aspects were designed accordingly. Furthermore, IRT participates in various technical work packages and plays a key role in test bed integration, validation and demonstration.
