1. A base station, comprising:
a memory configured to store a first pilot signal pattern that corresponds to a power variation between a first power level and a second power level, wherein the first pilot signal pattern is associated with a second pilot signal pattern stored on a second base station, and wherein the second pilot signal pattern corresponds to the power variation between the first power level and the second power level;
a processor coupled to the memory and configured to generate a first pilot signal in accordance with the stored first pilot signal pattern, wherein the first pilot signal is associated with a second pilot signal generated by the second base station; and
a communication unit coupled to the processor and configured to transmit the generated first pilot signal which comprises a first power level at a point of time detected by a mobile device, wherein the second pilot signal comprises a second power level at the point of time detected by the mobile device, wherein a third power level of a third pilot signal generated by a macro-cell base station and detected by the mobile device at the point of time is higher than either the first power level or the second power level.
