Wireless communication device and method

摘要

The present disclosure discloses a wireless communication device and method capable of adaptively permitting packet transmission or adjusting a threshold for packet transmission. An embodiment of said wireless communication device includes a reception circuit, a control circuit and a transmission circuit. The reception circuit measures signal energy, generates multiple energy measurement values, and generates multiple comparison results according to the energy measurement values and at least a threshold. The control circuit is operable to generate a transmission control signal according to the comparison results or to its derived information. The transmission circuit, coupled to the reception circuit and the control circuit, determines whether packet transmission is allowable according to the comparison results if the transmission control signal indicates a normal state, and the transmission circuit determines whether packet transmission is allowable according to the transmission control signal if the transmission control signal indicates an abnormal state.
