Summary:According to an embodiment of the present invention, a communication method of a base station comprises the following steps of: setting a first band as a communication band in the entire carrier frequency band of a base station including the first band and a second band; transmitting a synchronization signal by beamforming in one direction of two directions of a transportation means moving path in the first band; communicating with a terminal by beamforming in the same direction as the synchronization signal in the first band; and beamforming and transmitting a synchronization signal in the second band in the same direction as the synchronization signal in the first band. 본 발명의 일 실시예에 따른 기지국의 통신 방법은, 제1대역과 제2대역을 포함하는 상기 기지국의 전체 캐리어 주파수 대역에서 제1대역을 통신 대역으로 설정하는 단계; 상기 제1대역에서 교통 수단 이동로의 양 방향 중 한 방향으로 빔포밍하여 동기 신호를 송신하는 단계; 상기 제1대역에서 상기 동기 신호와 동일한 방향으로 빔포밍하여 단말과 통신하는 단계; 및 상기 제2대역에서 동기 신호를 상기 제1대역의 동기 신호와 동일한 방향으로 빔포밍하여 송신하는 단계;를 포함할 수 있다.
