| Abstract(in English) | The fifth-generation (5G) mobile communication system will utilize higher frequency bands with wider bandwidth for super high bit rate and large system capacity. In low-SHF-band, fully-digital Massive multiple-input multiple-output (MIMO) beamforming (BF) technology can be applied, and joint processing of digital fixed BF and channel state information (CSI)-based precoding (Digital FBCP) is proposed as one of the fully-digital methods. Additionally, it is assumed that multiple sites cover continuous areas early. Intersite coordination methods using Digital FBCP are proposed in order to transmit effectively multiple streams while decreasing intersite interference. For further improvement, in this paper, we study enhanced intersite coordination with beam search in Digital FBCP. Received power information applies interference-considered precoding method and determines applied area of the intersite coordination. Throughput performances of Digital FBCP with enhanced method are shown by link level simulation and this paper clarify that the enhanced method can improve throughput performance by utilizing received power information of beam search. |
