Station discovery processing method and wireless communication device

A station discovery processing method, comprising the steps of:

• determining whether data is received for specified waiting time;
• if no data is received for the specified waiting time, transmitting a discovery request frame;
• determining whether data is received in response to the transmission of the discovery request frame;
• if data is received in response to the transmission of the discovery request frame, determining whether the received data is a discovery response frame;
• and
• updating the waiting time if the received data is not a discovery response frame, or no data is received in response to the transmission of the discovery request frame.

A wireless communication device, comprising:

• a transmitting part that transmits data to other communication devices;
• a receiving part that receives data from other communication devices;
• a communication frame control part that generates the data to be transmitted from the transmitting part and detects data reception from the receiving part;
• a frame determining part that determines a frame type and validity of the data received from the receiving part;
• a transmission distance control part that decides a data transmission distance on the basis of notice from the communication frame control part and the frame determining part;
• and
• a power control part that controls transmission power of the data transmitted from the transmitting part so that the data is transmitted to other communication devices existing in a position of the transmission distance decided by the transmission distance control part.
• wherein if there is a transmission error in the data received from the receiving part in response to a discovery, request frame transmitted from the transmitting part, or if no data is received from the receiving part, the transmission distance control part decides a new transmission distance, the power control part controls the transmission power of the data to be transmitted, and the transmitting part transmits the discovery request frame again.

A wireless communication device of the present invention, comprising:

• a transmitting part that transmits data to other communication devices;
• a receiving part that receives data from other communication devices;
• a communication frame control part that generates the data to be transmitted from the transmitting part, transmits the generated data to the transmitting part after waiting for specified waiting time, and detects data reception from the receiving part;
• and
• a waiting time control part that decides waiting time before a discovery request frame is transmitted, on the basis of notice from the communication frame control part,
• wherein if no data is received from the receiving part in response to a discovery request frame transmitted from the transmitting part, the waiting time control part decides new waiting time and the transmitting part transmits the discovery request frame again after waiting for the new waiting time.
