Abstract

Long Term Evolution (LTE) constitutes the latest step
before the 4th generation (4G) of radio technologies designed to
increase the capacity and speed of mobile communications. To
support Multimedia Broadcast/Multicast Services (MBMS), LTE
offers the possibility to transmit Multimedia Broadcast multicast
service over a Single Frequency Network (MBSFN), where a
time-synchronized common waveform is transmitted from
multiple cells for a given duration. This enables over-the-air
combining, thus improving the Signal to Interference plus Noise
Ratio (SINR) and spectral efficiency (SE) significantly compared
to conventional MBMS operation. In this paper, we analytically
calculate the SE performance achieved in a MBSFN area for a
dynamically changing user topology and different modulation
and coding schemes (MCS). Finally, based on the SE
measurement, we determine the MCS scheme that either
maximizes or achieves a target SE for the corresponding user
distribution.
