Zusammenfassung:	The present invention relates to a method and an apparatus for transmitting and receiving a multi-carrier signal based on a filter bank, and more specifically, to a method and an apparatus for reusing a filter for transmitting and receiving a multi-carrier signal. According to an embodiment of the present invention, the method for reusing a filter for transmitting and receiving a multi-carrier signal is a communication method in a base station which communicates using a filter bank-based multi-carrier signal, and comprises: a step of assigning filters having non-orthogonality to a first terminal positioned in a cell to communicate; a step of selecting one filter set among two or more filter sets having orthogonality to a second terminal positioned on an edge of the cell; and a step of assigning at least one filter among filters included in the selected filter set to the second terminal to communicate. 본 발명은 필터뱅크 기반의 멀티 캐리어 신호를 송수신하기 위한 장치 및 방법에 관한 것으로 특히 필터를 재사용하여 멀티 캐리어 신호를 송수신하기 위한 장치 및 방법에 관한 것이다. 본 발명의 일 실시 예에 따른 방법은, 필터뱅크 기반의 멀티 캐리어 신호로 통신하는 기지국에서의 통신 방법으로, 셀 내부에 위치한 제1단말에 대하여 비직교성을 갖는 필터들을 할당하여 통신하는 단계; 상기 셀 가장자리에 위치한 제2단말에 대하여 둘 이상의 직교성을 갖는 필터 셋들 중 하나의 필터 셋을 선택하는 단계; 및 상기 선택된 필터 셋에 포함된 필터들 중 적어도 하나의 필터를 상기 제2단말에 할당하여 통신하는 단계;를 포함할 수 있다.
