TARGET DEVICE DISCOVERY METHOD OF COMMUNICATION DEVICE USING DIRECTIONAL COMMUNICATION IN A WIRELESS COMMUNICATION SYSTEM

摘要

PURPOSE: An opponent device discovery method using the directive communication of a communication device is provided to discover opponent devices existed within an area selected by a user by transmitting a pseudo probe request signal based on a directive method. CONSTITUTION: A communication device generates a pseudo probe request signal for finding out a device(300). The communication device transmits the generated pseudo probe request signal(310). The communication device receives a probe response signal from a direction where the pseudo probe request signal is transmitted(320). The communication device sets up a communication channel with an opponent device transmitting the probe response signal(330). [Reference numerals] (300) Generate a pseudo probe request signal; (310) Transmit the pseudo probe request signal using a directional communication module; (320) Receive a probe response signal; (330) Establish a communication channel using a wireless communication module; (AA) Start; (BB) End
