“…However, in a real scenario the increased bandwidth available for the broadcast layer does not always outweighs the joint interference caused by the Base Station (BS) self-unicast transmissions and the transmissions from near-by cells (inter-cell interference). Simulations of Further-evolved Multimedia Broadcast Multicast Service (FeMBMS in the 3GPP Release 14), reported a coverage degradation of 18% compared to the target coverage of the traditional broadcasting service [17]. A degradation of the broadcasting service coverage higher than 30% was reported in a field trial in Germany for LTE eMBMS [18].…”

Despite the recent advances in broadband penetration and accessibility, broadcasting networks continue to be the most efficient way for delivering media content to large areas independently of the user density. Nevertheless, a convergence of broadcasting services into the broadband networks is foreseen. In this context, Layered Division Multiplexing (LDM) allows the joint provision of unicast, multicast, and broadcast services in mobile cells infrastructure. Despite the success of LDM in broadcasting infrastructure, its practical application in Long Term Evolution networks providing Evolved Multimedia Broadcast Multicast Services (LTE eMBMS) and 5G-MBMS is more difficult. In this paper, we experimentally quantify the cellinterference and its impact on the network performance and Quality of Service. Our experiments reveal that the inter-cell interference margin for LTE eMBMS is about 3 dB higher compared to traditional LTE networks. If a layered architecture is incorporated this higher inter-cell interference would cause a reduction of approximately 19% of the Enhanced Layer (Lower Layer) coverage.

“…The benefits of time interleaving [8] and LDM (Layered Division Multiplexing) [9], also known as MUST (Multiuser Superposition Transmission) [10], were also taken into consideration. The signal acquisition and synchronization procedures were also evaluated as the existing numerology mismatch between data and control channels for large SFNs may lead to coverage issues as reported in [11] and [12]. Based on the findings of the Study Item, a Work Item may then standardize further improvements in Rel-16 while taking into account practical considerations such as implementation complexity and performance.…”

3GPP LTE eMBMS Release 14, also referred to as FeMBMS (Further evolved Multimedia Broadcast Multicast Service) or EnTV (Enhanced TV), is the first mobile broadband technology standard to incorporate a transmission mode designed to deliver Terrestrial Broadcast services from conventional High Power High Tower (HPHT) broadcast infrastructure. With respect to the physical layer, the main improvements in FeMBMS are the support of larger inter-site distance for Single Frequency Networks (SFN) and the ability to allocate 100% of a carrier's resources to the broadcast payload, with self-contained signaling in the downlink. From the system architecture perspective, a receive-only mode enables free-to-air (FTA) reception with no need for an uplink or SIM card, thus receiving content without UE registration with a network. These functionalities are only available in the LTE Advanced Pro specifications as 5G New Radio (NR), standardized in 3GPP from Release 15, has so far focused entirely on unicast. This paper outlines a physical layer design for NR-MBMS, a system derived, with minor modifications, from the 5G-NR specifications, and suitable for the transmission of linear TV and radio services in either single-cell or SFN operation. The paper evaluates the NR-MBMS proposition and compares it to LTE-based FeMBMS in terms of flexibility, performance, capacity and coverage.

The provision of terrestrial broadcast services using 3GPP technologies was enabled for the first time in LTE Advanced Pro Release (Rel‐) 14, in which the evolved Multimedia Broadcast Multicast Service (eMBMS) technology was enhanced to fulfill a wide set of requirements input by the broadcast industry. During the Enhancements for Television (EnTV) work item in Rel‐14, several modifications were realized affecting system architecture, core, and radio access, which include, an interface to grant control to broadcasters to establish audiovisual services, an application programming interface for developers to simplify access to eMBMS procedures, or a transparent delivery mode with native content formats, among others. At the radio layer, dedicated carriers with 100% broadcast content allocation, and also new OFDM numerologies to support larger intersite distances in Single Frequency Networks (SFNs), were enabled. The most significant change was the so‐called receive‐only mode which enables devices receiving broadcast content without the need for uplink capabilities, SIM cards, or network subscriptions, i.e. free‐to‐air reception.In Rel‐16, 3GPP carried out a study item to evaluate EnTV Rel‐14 against the terrestrial broadcast requirements for 5G defined in 3GPP TR 38.913. Two requirements were detected as not met: the ability to support SFNs with cell radii of up to 100 km and mobile reception with speeds up to 250 km h−1. A Rel‐16 work item standardized further improvements while taking into account practical considerations such as implementation complexity and performance. The improved system is known as LTE‐based 5G Terrestrial Broadcast, and also with the popular name 5G Broadcast.
