METHOD FOR ALLEVIATING PROBLEM OF HIDDEN NODE IN WIRELESS LOCAL AREA NETWORK SYSTEM

摘要

A method of mitigating a hidden node problem in a wireless LAN system is disclosed. The limited access interval setting method starts at a first time point within a beacon interval, and sets a first limited access interval used for channel access of the first terminal group, a second time after a predefined time from the first time point Starting at a time point, setting a second restricted access section used for channel access of the second terminal group, generating beacons including setting information of the first limited access section and setting information of the second limited access section And transmitting the generated beacon. Therefore, the frequency of occurrence of the hidden node problem can be lowered, thereby improving the use efficiency of the radio channel.
