ABSTRACT:
Systems and methods for enhancing the capacity of base stations are provided. A base station can operate in a time division duplex mode within a first frequency band. When a second frequency band is acquired for the base station's geographic region, a duplexer can be added to the base station. The base station can then operate in a frequency division duplex mode, where the first frequency band is used for base station downlink transmissions and the second frequency band is used for uplink transmissions.
