摘要： The present invention relates to an apparatus and a method for selection of a precoding matrix. In the present invention, a precoding matrix to enable an effective signal-to-noise ratio (ESNR) to have a maximum value with respect to a signal vector that requires retransmission is selected in a codebook and fed back to a transmitter. Accordingly, since the effective signal-to-noise ratio has the maximum value after the signal vector is retransmitted, it is possible to minimize a reception error probability of retransmission.

摘要： In a wireless communication system, when a transmission node has data to be transmitted to a reception node, it checks an acknowledgement slot of the current communication frame and transmits information regarding a reception available acknowledgement slot to the reception node through a request-to-send (RTS) slot in the current communication frame, and the reception node transmits information regarding the data slot available for receiving among at least one data slot corresponding to the reception available acknowledgement slot to the transmission node through a clear-to-send (CTS) slot corresponding to the data request slot in the current communication frame. Thereafter, the transmission node transmits data to the reception node through a reservation data slot of the subsequent communication frame until the message transmission fails or finishes.
摘要翻译： 在无线通信系统中，当传输节点具有要发送到接收节点的数据时，它检查当前通信帧的确认时隙，并通过请求发送将关于接收可用确认时隙的信息发送到接收节点 （RTS）时隙，并且接收节点通过清除发送（CTS）向发送节点发送关于可用于接收的数据时隙的信息到与发送节点对应的至少一个数据时隙中， 与当前通信帧中的数据请求时隙对应的时隙。 此后，传输节点通过后续通信帧的预留数据时隙向接收节点发送数据，直到消息传输失败或完成为止。
