transmitting unicast data, to the one or more UEs, in one or more subframes; and
transmitting synchronization signals, to the one or more UEs, within one or more broadcast subframes, wherein:
the synchronization signals are transmitted as single frequency network (SFN) transmissions synchronized with transmissions from one or more other base stations providing unicast coverage within the larger coverage area; and
transmitting the unicast data comprises transmitting the unicast data using a first cyclic prefix (CP) length that is different than a second CP length used for the one or more broadcast subframes.
