Abstract: A method and apparatus to use multiple pilot signals of different transmission power levels in a wireless communication system. A base station may broadcast in its coverage area at least two different pilot signals concurrently with each other but at different transmission power levels than each other. One of these pilot signals, transmitted at a normal pilot transmission power level for instance, may be for receipt and evaluation by certain UEs served by the base station, such as UEs that are not set to receive beamformed transmission of bearer traffic from the base station. Whereas another one of these pilot signals, transmitted at an increased pilot transmission power level for instance, may be for receipt and evaluation by other UEs served by the base station, such as UEs that are set to receive beamformed transmission of bearer traffic from the base station.
