Claim:
1. A user equipment, comprising: a radio-frequency (RF) transceiver capable of operating via time-division duplexing (TDD) in a first mode and capable of operating via frequency-division duplexing (FDD) in a second mode; and a processor coupled to the RF transceiver for selecting a mode of operation of the RF transceiver to communicate with a first spectrum holder; the processor to select the mode of operation of the RF transceiver in response to available spectrum not utilized by a second spectrum holder other than the first spectrum holder; the RF transceiver further being capable of operating via simultaneous TDD and FDD operation via carrier aggregation, wherein the processor selects simultaneous TDD and FDD operation in response to receiving an indication that there is a combination of a differing amount of available spectrum not utilized by the second spectrum holder or a larger amount of continuous spectrum not utilized by the second spectrum holder.
