Dynamic selection of spectrum access in a spectrum sharing context

A user equipment, comprising:na 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; anda 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.

An article of manufacture comprising a non-transitory computer-readable storage medium having instructions stored thereon that, if executed by a processor, result in:ncontrolling operation of a radio-frequency (RF) transceiver via time-division duplexing (TDD) in a first mode and controlling operation of the RF transceiver via frequency-division duplexing (FDD) in a second mode; andselecting the mode of operation of the RF transceiver based at least in part on the available spectrum not utilized by a primary spectrum holder (PSH);wherein the first mode is selected if there is a larger amount of uninterrupted available spectrum not utilized by the PSH.
