RRM aproaches in multicast transmission for supporting emerging 5G systems

This Thesis focused on fifth generation (5G) mobile networks. In particular on the Mobile Video, an application which will reach the 80% of the total amount of mobile traffic within 2019. 5G system aims to manage the ever-growing traffic demand, the huge number of connected devices e to improve the performance of current cellular networks. An important solution to such problems is exploiting group-oriented communications, well known as Multicasting, which exploit point-to-multipoint communications, useful to efficiently manage the available radio resources. This work focused on the multicast traffic management for the Mobile Video application and, in particular, on the Radio Resource Management (RRM). The Thesis is divided into four different research contribution. In the first chapter, application scenarios of multicast communications have been described together with the respective enhancement needed for their implementation. RRM plays an important role in multicast communication, and it has been dealt with in the following three chapters. In the second chapter, resource management issues were addressed in multicast communications in a Dense Heterogeneous network scenario, trying to balance customer services in poor channel conditions compared to those in good channel conditions. In the third chapter, the same issue was extended to Single Frequency Networks (SFNs), while in the fourth, radio resource management was dealt with in another perspective. Specifically, integrating into the LTE cellular system a non-orthogonal access technique (NOMA), typical of other broadcast systems.
