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. A base station for a wireless communication system is described. The wireless communication system includes a plurality of UEs, the plurality of UEs including at least a first UE and a second UE. The base station configured to serve the plurality of UEs. Further, base station is configured to provide a plurality of beams or spatial links for a wireless communication with the plurality of UEs, the plurality of beams including at least a first beam or spatial link for a wireless communication with the first UE and a second beam or spatial link for a wireless communication with the second UE, transmit to the first UE on the first beam or spatial link using frequency resources within a DL frequency band, transmit to the second UE on the second beam or spatial link using frequency resources within the DL frequency band, wherein the DL frequency band and a UL frequency band overlap at least partially, the overlapping parts of the DL frequency band and the UL frequency band defining an overlapping frequency band, concurrently transmit and receive in the overlapping frequency band, and cancel one or more transmission signals at least in presence of one or more concurrent receive signals from the first UE or from the second UE in the overlapping frequency band. The base station is configured to transmit to and receive from the first UE and the second UE using respective frequency resources in the overlapping frequency band.
