a base station transmitter operable to send a transmission on the shared radio medium.

8. The system of claim 6 , wherein the first transmitting device is a second classified base station and the second transmitting device is a first classified base station, wherein the second classified base station comprises:

a base station processor operable to listen for a reservation request signal (RRQ) sent by the first classified base station, wherein the base station processor is further operable to determine whether to send a transmission on the shared radio medium based at least on the listening; wherein the first classified base station is assigned a higher priority as compared to the second classified base station, when transmitting on the shared radio medium; and

a base station transmitter operable to send a transmission on the shared radio medium.

9. The system of claim 8 , wherein the base station processor is further operable to

determine that the first classified base station has scheduled a transmission based on the listening detecting the RRQ sent by the first classified base station, and based at least on the determination, the base station transmitter is operable to refrain from transmitting during the transmission of the first classified base station.

10. The system of claim 8 , wherein based at least on the determination, the base station processor is further operable to decide that the first classified base station has not scheduled a transmission,

and based at least on the decision, the base station transmitter is further operable to transmit a transmission using the shared radio medium.

11. The system of claim 10 , wherein the base station processor of the second classified base station is operable to schedule the transmission by at least:

directing the base station transmitter to:

send an RRQ during a RRQ time slot within the shared radio medium assigned to the second classified base station for channel reservation hand-shaking operation, and

send an RRS during a RRS time slot within the shared radio medium assigned to the second classified base station for channel reservation hand-shaking operation; and

directing a base station receiver to receive an uplink transmission on the shared radio medium.

12. A non-transitory computer-readable medium having program code recorded thereon, which causes channel reservation, the program code comprising:

code for detecting, by a first base station of a plurality of base stations sharing access to a shared radio medium of a network that is shared by a plurality of licensed network operators, transmission of one or more channel reservation signals, between a second base station of the plurality of base stations and a user equipment (UE) associated with the second base station, during a channel reservation hand-shaking operation conducted between the second base station and the UE; and
