Layered-Division Multiplexing in 5G New -Radio for Terrestrial Broadcast Services

The 5G system can deliver simultaneouslyunicast services, multicast services and broadcast services using the conventional high-power high- tower (HPHT) infrastructure and with the same spectrum.The Third Generation Partnership Project (3GPP) LTEevolved -multimedia broadcast- multicast service (eMBMS) have new features designed for Terrestrial Broadcast services in Release 14. A broadcast service means only receive mode, only downlink no uplink or inserting a SIM card not needed. In free to air reception without a SIM card or without user device registration with the network the content can be received. This specification is standardized in release 15. In this study a two layer Layered-Division Multiplexing (LDM) is used in 5G new radio (NR).A significant performance could be analyzed in a 5G- NRMBMS by using two layer LDM system for delivering terrestrial broadcast services. The performance analysis demonstrated by computer simulations. Using two-layer LDM in 5G-NRMBMS system a high-qualityservice can be provided to both handheld and fixed devices

Third Generation Partnership Project

In recent years, mobile operators are observing a growing demand of multicast services over radio cellular networks. In this scenario, multicasting is the technology exploited to serve a group of users which simultaneously request the same data content. Since multicast applications are expected to be massively exchanged over Fourth Generation (4G) systems, the Third Generation Partnership Project (3GPP) defined the Multimedia Broadcast Multicast Service (MBMS) standard. MBMS allows supporting multicast services over Long Term Evolution (LTE), the 4G wireless technology able to provide high quality services in mobile environments. Nevertheless, several issues related to the management of MBMS services are still open. The aim of this chapter is to analyze the challenges in supporting multicast services over LTE with particular attention to resource management, considered the key aspect for an effective provisioning of MBMS services over cellular networks.

In recent years, mobile operators are observing a growing demand of multicast services over radio cellular networks. In this scenario, multicasting is the technology exploited to serve a group of users who simultaneously request the same data content. Since multicast applications are expected to be massively exchanged over the forthcoming fifth generation (5G) systems, the third-generation partnership project (3GPP) defined the multimedia broadcast multicast service (MBMS) standard. MBMS supports multicast services over long-term evolution (LTE), and the 4G wireless technology provides high quality services in mobile environments. Nevertheless, several issues related to the management of MBMS services together with more traditional unicast services are still open. The aim of this chapter is to analyze the main challenges in supporting heterogeneous traffic over LTE with particular attention to resource management, considered as the key aspect for an effective provisioning of mobile multimedia services over cellular networks.
