ABSTRACT:
To perform rapid and sure connection processing in a wireless communication system that performs communication in compliance with a wireless communication method having a congestion control function. A starting station transmits a discovery request frame and determines whether or not data is received from other communication devices in response to transmitted data. As a result of receiving data and checking FCS (Field Check Sequence), if it is detected that a received frame has been destroyed, or if no data is received from the other communication devices, a transmission distance control part decides a new transmission distance and sends a command to control transmission power to a power control part of a transmitting part, and the power control part transmits the discovery request frame again on the basis of the newly decided transmission distance to repeat discovery processing. This prevents a collision of responses from plural communication devices and ensures discoveries of other communication devices.
