  The first 5G (5th generation wireless systems) New Radio Release-15 was
recently completed. However, the specification only considers the use of
unicast technologies and the extension to point-to-multipoint (PTM) scenarios
is not yet considered. To this end, we first present in this work a technical
overview of the state-of-the-art LTE (Long Term Evolution) PTM technology,
i.e., eMBMS (evolved Multimedia Broadcast Multicast Services), and investigate
the physical layer performance via link-level simulations. Then based on the
simulation analysis, we discuss potential improvements for the two current
eMBMS solutions, i.e., MBSFN (MBMS over Single Frequency Networks) and SC-PTM
(Single-Cell PTM). This work explicitly focus on equipping the current eMBMS
solutions with 5G candidate techniques, e.g., multiple antennas and millimeter
wave, and its potentials to meet the requirements of next generation PTM
transmissions.
