Abstract
(KO) 기지국과 복수의 UE 사이의 정보를 통신하기 위한 무선 통신 네트워크가 개시된다. 본 발명의 제 1 측면에 따르면, 상기 기지국은 공간 다양성 및 주파수 분할 다중화(FDM) 통신을 이용하여 복수의 UE와 동시에 송수신한다. 본 발명의 제 2 측면에 따르면, 상기 기지국은 공간 다양성 없이 주파수 분할 다중화(FDM) 통신을 이용하여 복수의 UE와 동시에 송수신한다. 본 발명의 제 3 측면에 따르면, 상기 기지국은 공간 다양성 및 시분할 다중화(TDM) 통신을 이용하여 복수의 UE와 동시에 송수신한다. 본 발명의 제 4 측면에 따르면, 상기 기지국은 공간 다양성 없이 시분할 다중화(TDM) 통신을 이용하여 복수의 UE와 동시에 송수신한다.
