multimedia services by utilizing the Multimedia Broadcast/Multicast Service
(MBMS) over a Single Frequency Network (MBSFN). During MBSFN
transmission a time-synchronized common waveform is transmitted from
multiple cells. The 3rd Generation Partnership Project (3GPP) has specified that
Point-to-Multipoint (PTM) transmission can be used in combination with
MBSFN to provide MBMS-based services. In this paper we evaluate the
combined transmission scheme in terms of Resource Efficiency (RE). The
evaluation is performed through simulation experiments for various user
distributions and LTE network configurations. The experiments are conducted
with the aid of a proposed algorithm, which estimates the Spectral Efficiency
(SE) of each cell and the RE of the network, and is also able to formulate the
optimal network deployment that maximizes the network?s RE. For each of the
examined scenarios, we present the most efficient solution (in terms of RE)
selected by our algorithm and we compare it with other transmission schemes.10aLTE10aMBMS10aMBSFN1 aBouras, Christos1 aAlexiou, Antonios1 aPapazois, Andreas1 aKokkinos, Vasileios1 aAsimakis, Konstantinos  uhttps://telematics.upatras.gr/telematics/publications/combining-mbsfn-and-ptm-transmissions-schemes-resource-efficiency-lte-networks
