    • Embodiments of a millimeter-wave communication station and method for multiple-access beamforming in a millimeter-wave network are generally described herein. In some embodiments, an initiating station performs multiple-access beamforming with one or more responding stations by announcing a number of sector-sweep (SS) slots of a beamforming training (BFT) period and a number of SS frames of each SS slot. One or more SS frames are received from one or more of the responding stations within one of the SS slots of the BFT period. The initiating station transmits one or more SS feedback frames to the responding stations within the one SS slot to indicate an antenna configuration to the responding stations for communication with the initiating station. The responding stations transmit a limited number of SS frames per SS slot based on the number of SS frames announced by the initiating station and transmit any additional SS frames in a next SS slot of the beamforming training period. Each SS frame contains an indication to the initiating station of an antenna configuration for communication with the responding station.
    • 在此总体上描述毫米波通信站和用于毫米波网络中的多址波束成形的方法的实施例。 在一些实施例中,发起站通过宣告波束形成训练(BFT)时段的数目的扇区扫描(SS)时隙和每个SS时隙的SS帧的数目来执行与一个或多个响应站的多址波束成形。 从BFT周期的SS时隙之一内的一个或多个响应站接收一个或多个SS帧。 发起站将一个或多个SS反馈帧发送到一个SS时隙内的响应站,以向响应站指示天线配置以与发起站进行通信。 响应站根据发起站通告的SS帧的数量,发送每个SS时隙有限数量的SS帧,并在波束成形训练周期的下一个SS时隙中发送任何附加SS帧。 每个SS帧包含一个指示给发起站的天线配置,用于与响应站进行通信。

    • A system and method are provided to trigger re-beamforming based on an algorithm that assesses various link characteristics. The algorithm is based on the ability of a 60 GHz receiving device to track and feedback a Received Signal Strength Indication (RSSI) to a 60 GHz data packet transmitter. By automatically analyzing RSSI values across a range of data packets, including consecutive data packets, a link degradation trend is predicted. When link degradation crosses, or is predicted to cross, a predetermined threshold, re-beamforming is triggered by the algorithm. Variables in the algorithm and the predetermined thresholds used by the algorithm can be automatically or manually modified to maintain a balance between appropriately triggering the re-beamforming when the conditions arise without unnecessarily triggering the re-beamforming thereby causing unneeded interruptions in regular data flow.
    • 提供了一种基于评估各种链路特性的算法来触发重新波束形成的系统和方法。 该算法基于60GHz接收设备跟踪并将接收信号强度指示(RSSI)反馈到60GHz数据分组发射机的能力。 通过自动分析包括连续数据包在内的一系列数据包的RSSI值,可以预测链路退化趋势。 当链路劣化交叉或被预测为交叉预定阈值时,由该算法触发重新波束形成。 可以自动地或手动地修改算法中使用的算法和预定阈值的变量,以便在条件出现时适当地触发重新波束成形之间保持平衡,而不必不必要地触发重新波束形成,从而导致规则数据流中不必要的中断。
