    • Provided are a method of transmitting a dedicated reference signal (DRS), a method of receiving a DRS, and a feedback method of a terminal. The method of transmitting a DRS includes determining a DRS transmitting resource for at least one terminal which is a target of transmission, and transmitting the DRS using the determined transmission resource and notifying the terminal of information about layer used by the terminal. The method of receiving a DRS includes determining a DRS receiving resource, receiving information about layer used by a terminal from a serving cell base station, and receiving the DRS for the terminal using the determined reception resource and the information about layer. Accordingly, a terminal can find the position and sequence of its DRS. In particular, in the case of multi-user multiple input multiple output (MU-MIMO) or joint scheduling, it is possible to prevent or remove signal interference using the DRS of another terminal.
    • 提供了发送专用参考信号(DRS),接收DRS的方法和终端的反馈方法的方法。 发送DRS的方法包括确定作为传输对象的至少一个终端的DRS发送资源,以及使用所确定的传输资源发送DRS,并向终端通知关于终端使用的层的信息。 接收DRS的方法包括确定DRS接收资源,从服务小区基站接收终端使用的层的信息,以及使用所确定的接收资源和关于层的信息来接收终端的DRS。 因此,终端可以找到其DRS的位置和顺序。 特别地,在多用户多输入多输出(MU-MIMO)或联合调度的情况下,可以使用另一终端的DRS来防止或消除信号干扰。

    • Disclosed is a method for transmitting and receiving control information. The method for transmitting control information according to the present invention, in a mobile communication system in which a control channel region and a data channel region are separated from each other, comprises the steps of: determining a control channel resource for transmitting control information by means of the data channel region; and transmitting the control information using the determined control channel resource. According to the present invention, a capacity for control information, which increases for multiple user multiple-input multiple-out (MIMOs) in a heterogeneous network environment, for heterogeneous network interference control using carrier aggregation, for frequent use of a multicast-broadcast single frequency network (MBSFN) subframe, and for a CoMP transmission control, may be satisfied. Further, an adaptive resource allocation based on a requested capacity for control information may be enabled, and the efficient utilization of resources may also be enabled.
    • 公开了一种发送和接收控制信息的方法。 在控制信道区域和数据信道区域彼此分离的移动通信系统中,根据本发明的用于发送控制信息的方法包括以下步骤:确定用于通过装置发送控制信息的控制信道资源 的数据通道区域; 以及使用所确定的控制信道资源发送控制信息。 根据本发明,对异构网络环境中的多用户多输入多输出(MIMO)增加的控制信息的容量用于使用载波聚合的异构网络干扰控制,用于频繁使用多播广播单 频率网络(MBSFN)子帧,以及用于CoMP传输控制。 此外,可以启用基于所请求的控制信息容量的自适应资源分配,并且还可以实现资源的有效利用。
