Abstract
A method and apparatus for minimizing interference in a wireless communication system. A base transceiver station transmits and receives over a first frequency band and a second frequency band. The maximum range of the first frequency band can be smaller than the maximum range of the second frequency band. Alternatively, the maximum range of the first frequency band can be larger than the maximum range of the second frequency band. Further, the maximum range of the second frequency band can vary based upon factors such as the capacity of the first frequency band and the amount of interference on the first frequency band. A control channel for the second frequency band which is measured for determining whether to handoff from the first frequency band to the second frequency band can be transmitted within the first frequency band.
