摘要
The timing used by communication equipment in a licensed frequency band by is used by the communication equipment for communication in an unlicensed frequency band. Time divisions, such as frames, subframes, timeslots, and symbol times, defined for use in the licensed frequency band are used by the communication equipment to communicate in the unlicensed frequency band. Before a transmitting device transmits within the unlicensed frequency band, the unlicensed frequency band is monitored for radio frequency energy to determine if the spectrum is currently being used. If no energy is detected, or the level is below a threshold, it is determined that the unlicensed band can be used by the transmitter.
