network beyond 3G, is designed to support the explosion in
demand for bandwidth-hungry multimedia services that are
already experienced in wired networks. To support Multimedia
Broadcast/Multicast Services (MBMS), LTE offers functionality
to transmit MBMS over a Single Frequency Network (MBSFN),
where a time-synchronized common waveform is transmitted
from multiple cells for a given duration. This significantly
improves the Spectral Efficiency (SE) compared to conventional
MBMS operation. The achieved SE is mainly determined by the
Modulation and Coding Scheme (MCS) utilized by the LTE
physical layer. In this paper we propose and evaluate four
approaches for the selection of the MCS that will be utilized for
the transmission of the MBSFN data. The evaluation of the
approaches is performed for different users? distribution and
from SE perspective. Based on the SE measurement, we
determine the most suitable approach for the corresponding
users? distribution.10aLTE10aMBMS10aMBSFN10aMCS1 aBouras, Christos1 aAlexiou, Antonios1 aPapazois, Andreas1 aKokkinos, Vasileios1 aTsichritzis, George  uhttp://telematics.upatras.gr/telematics/publications/efficient-mcs-selection-mbsfn-transmissions-over-lte-networks
