Abstract
A channel identification system and method are provided to automatically identify ports of a base station (e.g., an eNodeB) to route downlink signals to appropriate access points in a telecommunication system. Primary and secondary synchronization signals may be identified in the downlink signals transmitted by the base station. A broadcast channel may be decoded for a downlink signal including the primary and secondary synchronization signals. Signal information may be used to extract a first cell-specific reference signal and generate a second cell-specific reference signal corresponding to one or more ports of the base station. The first and second cell-specific reference signals may be correlated to verify the identity of the channel corresponding to the ports of the base station.
