Combining MBSFN and PTM Transmission Schemes for Resource Efficiency in LTE Networks
Long Term Evolution (LTE) systems allow the transmission of rich 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, the authors 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.
