Efficient multicasting of critical messages is of essential importance in public safety and commercial multimedia cellular networks. The authors study the effectiveness of using the aid of micro Base Stations (mBSs) to enhance the spectral efficiency of multicast distribution in a wireless cellular network. Coloring oriented adaptive rate scheduling algorithms are considered, including such that temporally employ TDMA schedules with reuse levels of 1, 3, 4 and 7 over a cellular arrangement. These schemes are used to regulate multicast transmissions executed by Macro Base Stations (MBSs) and to jointly schedule macro and micro Base Stations (mBSs). They examine the utility of using the aid of mBSs in potentially improving multicasting performance.
