Abstract: The present invention relates to an apparatus and a method for avoiding signal interference between access points in an unlicensed band. The present invention provides an apparatus for avoiding interference between access points including an adjacent AP presence determination unit that determines whether or not a second access point adjacent to a first access point is present; an operation channel overlapping determination unit that determines whether or not operation channels of the first access point and the second access point overlap with each other when the second access point is determined to be present; a non-overlapping channel setting determination unit that determines whether or not non-overlapping operation channel setting is available when the operation channels of the first access point and the second access point are determined to overlap with each other; and a channel use control unit that controls the operation channel of the first access point to be shared with the second access point when the non-overlapping operation channel setting is determined to be unavailable. According to the present invention, an inter-OBSS interference problem can be addressed, and effective channel sharing becomes available while network-wide overhead is minimized through simple message exchange between the access points.

Abstract: PURPOSE: A frequency allocating method for a frequency sharing system is provided to recognize available channel information in a frequency sharing system or a frequency allocation device by classifying each sub frequency resource. CONSTITUTION: If available sub frequency resources do not exist, an apparatus determines the existence of conditional available sub frequency resources(520, 530). If the conditional available sub frequency resource exists, the apparatus decides whether the regulation is satisfied(540). If so, the apparatus allocates conditional available sub frequency resources to a frequency sharing system(541). The apparatus determines the existence of the allocated sub frequency resource using RAT(Radio Access Technology)(550).
