Abstract

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

Highlights

Within 2017 to 2020 the data signal traffic increases by seven-fold and more than 80 percent data signal traffic for high definition (HD) videos
„further evolved multi-mediamulticast broadcast service‟ (FeMBMS) system was introduced in release-14 with some new functions to deliver terrestrial broadcast services
In this study the performance analysis will evaluate by using two-layer Layered-Division Multiplexing (LDM) in 5G New Radio MBMS (5G NRMBMS)

Summary

Introduction

Within 2017 to 2020 the data signal traffic increases by seven-fold and more than 80 percent data signal traffic for high definition (HD) videos. This high data traffic puts more pressure on mobile operators to allocate more spectrums and to use the latest technologies to improve channel efficiency. LTE „enhanced Multicast/Broadcast Multimedia Service‟(eMBMS) mobile broadcast services already included. For 5G broadcasting the architecture introduces receive -only mode, without SIM and without uplink.
