Claim Text:
1. A communication device comprising: a transceiver configured to communicate with a counterpart communication device using a television (TV) white space; a measurer configured to measure power of a signal received from the counterpart communication device; a memory configured to store an initial power level; and a controller configured to determine a transmission power level based on the power measured by the measurer and control the transceiver to communicate with the counterpart communication device while gradually increasing a transmission power of a signal transmitted to the counterpart communication device from the initial power level to the transmission power level, wherein, when transmission to the counterpart communication device pauses and then resumes, the controller is further configured to reset the transmission power to the initial power level, and control the transceiver to communicate with the counterpart communication device while gradually increasing the transmission power from the initial power level to the transmission power level.
