Abstract
A method according to an embodiment of the invention includes receiving and transmitting signals over a time division duplex (TDD) communication path. Signals are received over the TDD communication path via a first portion of a first frequency band. The first frequency band is adjacent to a second frequency band and to a third frequency band. The first frequency band is different from the second frequency band and from the third frequency band. A first frequency division duplex (FDD) communication path can be operable in the second frequency band. A second FDD communication path can be operable in the third frequency band. Signals are transmitted over the TDD communication path via a second portion of the first frequency band that is different from the first portion of the first frequency band.
