Abstract
Methods and systems are provided for enabling a base station to receive signals and synchronization information from neighboring base stations over a frequency band designated for transmissions to mobile devices. In embodiments, a cancellation signal is used to cancel antenna overload resulting from a base station's own transmission. By negating antenna overload, the base station may listen for synchronization signals output by neighboring base stations over the frequency band designated for transmission to mobile devices, such as a downlink band, for example. In embodiments, synchronization signals are used by the base station and/or a server to detect when synchronization failures occur at the base station and/or neighboring base stations. Synchronization signals from a neighboring base station may be used to re-synchronize a base station that have experience such a failure, in some embodiments.
