Abstract: Aspects of the present disclosure relate to wireless communications and, more particularly, to synchronization for standalone long term evolution (LTE) broadcast. In one aspect, a method is provided which may be performed by a wireless device such as a base station (BS). The method generally includes providing unicast coverage to one or more user equipments (UEs) in a unicast coverage area within a larger coverage area, transmitting unicast data in one or more subframes, and transmitting synchronization signals within one or more of the broadcast subframes, wherein the broadcast 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.
