Multicasting over 6G Non-Terrestrial Networks: a Softwarization-based Approach
Multicast/broadcast delivery is a critical challenge of future sixth-generation (6G) mobile networks where massive internet of things deployment and extended reality multimedia such as teleportation are target application scenarios. Non-terrestrial networks (NTNs) are considered essential for the success of 6G, which aims to provide true "global" services by extending mobile access worldwide, thus overcoming the coverage limit of current terrestrial networks (TNs). This paper discusses how the main distinguishing features of NTNs can be effectively exploited for 6G multicasting. Furthermore, in line with the evolution of future 6G networks toward softwarized systems, we evaluate the potential of using the softwarization paradigm in the heterogeneous TN/NTN architecture to deliver multicast services.
