    • A method for transmitting and receiving information in a base station which supports multi-user multiple-input multiple-output (MU-MIMO) according to an embodiment of the present invention comprises the steps of transmitting, to a connected terminal, a first terminal identifier to identify the terminal and a first base station identifier to identify a base station; receiving, from the terminal, feedback related to a communication channel; performing scheduling for MU-MIMO transmission to the terminal based on the feedback; and configuring a control channel including interference cancellation information based on the scheduling information. According to the method of the present invention, the terminal can effectively cancel an interference signal transmitted to another terminal using minimum information. At this time, the terminal can perform interference cancellation using a terminal receiver without interference cancellation capability like an existing terminal. That is, the interference cancellation can be performed without additional terminal complexity and thus the base station can improve MU-MIMO transmission performance of a cell. Also, the terminal can derive information necessary for demodulation of a data channel signal transmitted to another terminal using proposed control channel information and can use the derived information for self-interference cancellation. Also, the base station can perform MU-MIMO scheduling according to a channel state of the terminal in the cell through a proposed control channel structure and can dynamically change an interference cancellation instruction for any terminal.
    • 根据本发明实施例的用于在支持多用户多输入多输出(MU-MIMO)的基站中发送和接收信息的方法包括以下步骤:向连接的终端发送第一终端标识符 以识别终端和用于识别基站的第一基站标识符; 从终端接收与通信信道相关的反馈; 基于所述反馈对所述终端进行MU-MIMO传输的调度; 以及基于所述调度信息配置包括干扰消除信息的控制信道。 根据本发明的方法,终端可以使用最小信息有效地消除发送到另一终端的干扰信号。 此时,终端可以使用没有干扰消除能力的终端接收机来执行干扰消除,如现有终端。 也就是说,可以在没有额外的终端复杂度的情况下执行干扰消除,并且因此基站可以提高小区的MU-MIMO传输性能。 此外,终端可以使用提出的控制信道信息来导出解调发送到另一终端的数据信道信号所需的信息,并且可以使用导出的信息进行自干扰消除。 此外,基站可以通过所提出的控制信道结构,根据小区中的终端的信道状态进行MU-MIMO调度,并且可以动态地改变任何终端的干扰消除指令。

    • The present invention relates to sounding operation method and apparatus in a wireless communication system with dynamic change of uplink control channel resources. In detail, a method of transmitting a sounding reference signal of a terminal in the wireless communication system according to the present invention is characterized by including the steps of receiving uplink and downlink setting information from a base station, checking the occurrence of collision between a physical uplink control channel (PUCCH) and a sounding reference signal (SRS) based on the uplink and the downlink setting information, and skipping the SRS transmission when the collision occurs. According to the present invention, the collision between the SRS and the uplink control channel resources can be effectively solved without increasing power consumption burden of the terminal, or without excessive restrictions for SRS transmission sub-frames or sounding bands.
