Dynamic selection of spectrum access in a spectrum sharing context

An article of manufacture comprising a non-transitory computer-readable storage medium having instructions stored thereon that, if executed by a processor, result in:

• controlling 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;
• and
• selecting 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.

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;
• wherein the processor dynamically switches between the first mode and the second mode in response to receiving an indication that spectrum utilized by the second spectrum holder is freed and made available to the network operator, or that spectrum not utilized by the second spectrum holder is reclaimed for use 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:

• controlling 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;
• selecting 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);
• and
• operating the RF transceiver in a combination of the first mode and the second mode via carrier aggregation if a differing amount of available spectrum is not utilized by the PSH and a larger amount of uninterrupted spectrum is not utilized by the PSH.
