    • Provided is a method for managing resource in a high capacity wireless communication system capable of communicating with two or more users in a multi-input multi-output (MIMO) scheme when a base station transmits data. The includes: transmitting a MU-MIMO request-to-send (RTS) message to stations intending to transmit data in the MIMO scheme, and sequentially receiving a clear-to-send (CTS) message from stations intending to receive the data; transmitting a transmission ACK message to the stations, wherein the transmission ACK message includes information which prevents data collision during a time of data transmission to the stations and ACK signal; and configuring data to be transmitted to the stations into aggregated packets (A-MPDUs), transmitting the A-MPDUs to the stations in the MIMO scheme, and receiving a block ACK message from the stations.
    • 提供了一种用于在基站发送数据时能够以多输入多输出(MIMO)方案与两个以上的用户通信的高容量无线通信系统中的资源的方法。 包括:向正在MIMO方案中发送数据的站发送MU-MIMO请求发送(RTS)消息,以及顺序地接收来自旨在接收数据的站的清除发送(CTS)消息; 向所述站发送传输ACK消息,其中所述传输ACK消息包括在数据传输到所述站的时间期间防止数据冲突的信息和ACK信号; 并将要发送到站的数据配置为聚合报文(A-MPDU),在MIMO方案中将A-MPDU发送到站,以及从站接收块ACK消息。
