HIDDEN NODE DETECTION METHOD AND APPARATUS IN WIRELESS COMMUNICATION SYSTEM |
摘要 |
Provided is a hidden node detection method and apparatus in a wireless communication system, the apparatus including a sensing unit to sense a first communication device transmitting a data signal from among a plurality of communication devices sharing a wireless channel, a transmitter to generate a reception notification signal in response to the sensing, and transmit the reception notification signal to the a plurality of communication devices through a band identical to a transmission band of the data signal, and a controller to prevent a collision with the data signal transmitted from the first communication device through the wireless channel by delaying processing of a data transmission request when the data transmission request is input from a second communication device among the plurality of communication devices while maintaining the transmitting of the reception notification signal. |
