Abstract
Methods and systems are provided for enabling a base station to listen and receive signals from neighboring base stations over a frequency designated for transmission to mobile devices for the detection of a synchronization failure. Embodiments provided herein enable the base station to cancel out its own transmission signal(s), which overloads the base station's own antenna 816 due to proximity. By cancelling out the base station's own signal, the base station listens and receives synchronization signals from one or more neighboring base stations over the frequency designated for transmission in a wireless communications network. A synchronization signal may be used, by the base station or as relayed to a server, to determine if the base station or the neighboring base station has experienced a synchronization failure.
