Spectral Efficiency Performance of MBSFN-Enabled LTE Networks

Executive Summary

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.
