    • Provided is a method for retransmitting data based on antenna scheduling in a MIMO system to which a spatial multiplexing technique is applied. The method includes the steps of: (a) at a transmitter side, modulating an input packet into transmittable data to transmit to a receiver side; (b) at the receiver side, estimating channel values from the packet transmitted from the transmitter side, and selecting transmitting and receiving antennas for transmitting the next packet from the estimated channel values; (c) detecting whether an error is present in the packet or not, and transmitting a feedback signal to the transmitter side, the feedback signal including information on whether or not to transmit the packet and a list of the selected transmitting antennas; and (d) at the transmitter side, retransmitting the transmitted packet or transmitting the next packet through the transmitting antennas designated by the receiver side depending on the feedback signal.
    • 提供了一种在应用空间复用技术的MIMO系统中基于天线调度重传数据的方法。 该方法包括以下步骤:(a)在发射机侧,将输入分组调制成可发送数据,以发射到接收机侧; (b)在接收机侧,从发射机侧发送的分组估计信道值,以及从所估计的信道值中选择用于发送下一个分组的发射和接收天线; (c)检测分组中是否存在错误,并且向发射机侧发送反馈信号,所述反馈信号包括关于是否发送分组的信息和所选择的发送天线的列表的信息; 和(d)在发射机侧,根据反馈信号通过由接收机侧指定的发送天线来重传所发送的分组或发送下一分组。
