    • PROBLEM TO BE SOLVED: To provide an enhanced bidirectional beam forming protocol to perform bidirectional beam forming operations to reduce training overhead and link latency during beam forming operations.SOLUTION: A wireless device has an antenna control module operative to initiate beam formation operations using an iterative training scheme to form a set of communications channels for a wireless network. The antenna control module transmits training signals and feedback information to a peer device via a transceiver and a phased antenna array using partially or fully formed high rate channels, and iteratively determines antenna-array weight vectors for a directional transmit beam pattern for the phased antenna array using feedback information from the peer device.
    • 要解决的问题:提供增强的双向波束形成协议以执行双向波束形成操作以减少波束形成操作期间的训练开销和链路等待时间。解决方案:无线设备具有天线控制模块,用于使用迭代来启动波束形成操作 培训方案,形成无线网络的一组通信渠道。 天线控制模块经由收发机和使用部分或完全形成的高速率信道的相控天线阵列将训练信号和反馈信息发送到对等设备,并且迭代地确定用于相控天线阵列的定向发射波束图案的天线阵列权重向量 使用对等设备的反馈信息。
