“…The maximum radiated power already includes the output power, feeder losses and antenna gain for a macrocell BS [22]. For the LDM configuration modeling we consider four different injection levels in the range from -7 to -4 dB, referenced to the Core Layer radiated power [7], [4]. For each injection level and MCS configuration a different pair of minimum SNR is required for decoding each layer [7], [4].…”

“…However, this means that for demodulating their unicast content each mobile device must decode the broadcast/multicast signal causing an additional computational requirement, power consumption and a faster battery drain. In a standalone broadcasting system, a use case where the Core Layer deliver a robust high-definition media service to mobile receivers and the Enhanced Layer ultra-high definition content to fixed receivers, address the issue of battery power consumption in mobile receivers [7], [4], [1].…”

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.
