  • Patent number: 8842525
    Abstract: The present document describes a system and method for extending a wireless communication coverage area of a cellular wireless base station transceiver (BTS) to enable control signaling and identification of mobile stations not currently within a coverage area of an existing beamform antenna pattern of the BTS, for example. A cellular BTS may scan through dead zones of coverage areas provided by the BTS to identify mobile stations not within the coverage area of the BTS, but within a possible service area of the BTS. In addition, the BTS may receive a relaying control signal from a mobile station located within the coverage area of the BTS, and the signal will indicate a location of another mobile station not within the coverage area of the BTS but within the service area of the BTS. In either example, the BTS may attempt to provide a coverage area to the mobile station located in the control signaling dead zone, for example.
