    • 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。

    • Provided is a method for retransmitting packet in a Multiple Input Multiple Output (MIMO) system. The method includes: in a receiving block, decoding packets received from a transmitting block and detecting whether an error exists or not in the packets; if the error is detected, transmitting a negative acknowledgement (NACK) signal informing transmission failure of the packets to the transmitting block; calculating channel quality information (CQI) values for transmission-failed packets after performing successive interference cancellation (SIC) with respect to all antenna combinations to retransmit the transmission-failed packets; and selecting an antenna combination having CQI values of the transmission-failed packets which are equal to or greater than respective initial CQI values of the transmission-failed packets among the antenna combinations, and transmitting information of the selected antenna combination to the transmitting block.
    • 提供了一种在多输入多输出(MIMO)系统中重传分组的方法。 该方法包括:在接收块中,解码从发送块接收的分组,并检测分组中是否存在错误; 如果检测到错误,则发送否定确认(NACK)信号,通知分组对发送块的传输失败; 在对所有天线组合执行连续干扰消除(SIC)之后计算传输失败分组的信道质量信息(CQI)值,以重发传输失败分组; 以及选择天线组合中具有等于或大于发送失败分组的初始CQI值的发送失败分组的CQI值的天线组合,并将所选择的天线组合的信息发送到发送块。
