무선 통신 시스템 셀 간 간섭을 감소시키는 방법 및 이를 위한 장치
摘要：
본출원에서는무선통신시스템에서서빙셀이인접셀과의협력적빔포밍을통한하향링크신호를송신하는방법이개시된다. 구체적으로, 상기인접셀로하나이상의서브프레임을지정하는제 1 서브프레임정보를전달하는단계, 상기하나이상의서브프레임에서상기인접셀로미치는간섭이일정한특성을갖도록빔(beam)을형성하는, 하나이상의 PMI (Precoding Matrix Index)를포함하는제 1 PMI 제한관련정보를상기서빙셀의단말로송신하는단계, 상기제 1 PMI 제한관련정보에기반하여상기하나이상의서브프레임에서측정된제 1 CSI (Channel Status Information) 보고를상기서빙셀의단말로부터수신하는단계, 및상기제 1 CSI 보고에기반하여, 상기서빙셀의단말로하향링크신호를송신하는단계를포함하고, 상기인접셀은상기인접셀의단말이상기하나이상의서브프레임에서측정한인접셀 대응 CSI 보고를수신하는것을특징으로한다.
摘要（英）：

The method for transmitting downlink signals via the cooperative beam-forming with the neighboring cell is the serving cell in a wireless communication system is disclosed in the present application. Specifically, the first sub-step for transmitting the frame information, the one or more PMI from the one or more sub-frames to form a beam (beam) is on the cell interfere the adjacent so as to have a certain property that specifies the neighbor cell at least one sub-frame (Precoding Matrix Index) of claim 1 PMI restriction information to the claim 1 CSI (Channel Status information measured at terminal stage, wherein 1 PMI restriction information about the one or more sub-frames based on sending to the serving cell containing ) the step of receiving from the terminal of the serving cell reports, and the first on the basis of CSI reported, cells comprising the step, and the neighbor for transmitting a downlink signal to the mobile station in the serving cell the UE of the neighbor cell It characterized by: receiving a neighboring cell corresponding CSI measurement report from the at least one sub-frame.
