1차 면허권 시스템이 존재하는 환경에서의 주파수 할당 방법 및 장치가 개시된다. 본 발명의 실시예들은 각 서브 주파수 자원을 이용 상황에 따라 분류된 복수의 주파수 셋들을 이용하여 1차 면허권 시스템이 존재하는 주파수 환경에서 주파수 자원 관리를 원활하게 수행할 수 있다. 또한 본 발명의 실시예들은 동종의 주파수 공유 시스템이 존재하는 경우 해당 주파수 자원을 우선적으로 할당함으로써 주파수 공유를 위한 오버헤드를 줄일 수 있다.
Abstract:
Disclosed are a frequency assignment method and a device thereof in environment in which a first license system exists. Frequency resources are smoothly managed in a frequency environment in which the first license system exists by using a plurality of frequency sets in which each sub frequency resources are classified according to a usage situation. According to an embodiment of the present invention, the present invention can reduce overheads for sharing frequencies by primarily assigning the frequency resource when the same kind of a frequency sharing system exists.

Abstract:
Disclosed is a coexistence management system and method for measuring channel information between frequency-sharing devices. The system includes a plurality of CE (coexistence enabler) in each of WSOs (white space objects) having at least one measuring capability, capable of measuring channel information about an active channel using; a CM (coexistence manager) checking the measuring capability of the WSO with at least one CE in its group and receiving the channel information about the active channel from at least one WSO in another group neighboring according to the checking result; and a CDIS (coexistence discovery and information server) registering at least one measuring capacity of each of the WSOs.
Abstract:
PURPOSE: A frequency sharing apparatus and method thereof are provided to allocate idle frequency to a wireless communication device and to select a recognition wireless communication device. CONSTITUTION: A receiving unit(310) receives information about an interference influence area from a recognition wireless communication device. A frequency allocation unit(320) selects the recognition wireless communication installation having the minimum interference effect area size. The frequency allocation unit allocates the idle frequency to the selected recognition wireless communication unit.
Abstract:
PURPOSE: A frequency sharing apparatus based on frequency set classification in a first license system is provided to use a corresponding channel in a frequency sharing system based on frequency set classification. CONSTITUTION: An information acquiring unit(630) acquires information about frequency sets. A plurality of frequency sets is generated by the separation of target frequency resources which are allocated to a first license system. An allocation unit(640) allocates sub frequency resources to a frequency sharing system. One or more sub frequency resources is included in frequency sets.
