    • A system and method for discovering and tracking communication directions is disclosed herein. In one embodiment, communication directions for two devices with asymmetric antenna systems are discovered. In one embodiment, a contention access period (CAP) is partitioned into an association CAP and a regular CAP, either of which may be further partitioned into sub-CAPs corresponding to different reception directions. In one embodiment, an association request command is transmitted by a device at different association sub-CAPs to train a transmission direction of the device. In one embodiment, further training is performed to find the best communication directions, as collisions may occur when association request commands are transmitted at different association sub-CAPs.
    • 本文公开了一种用于发现和跟踪通信方向的系统和方法。 在一个实施例中,发现具有不对称天线系统的两个设备的通信方向。 在一个实施例中,争用访问周期(CAP)被划分为关联CAP和常规CAP,其中任一个可以被进一步划分为对应于不同的接收方向的子CAP。 在一个实施例中,由不同关联子CAP的设备发送关联请求命令,以训练设备的传输方向。 在一个实施例中,执行进一步训练以找到最佳的通信方向,因为当在不同的关联子CAP发送关联请求命令时可能发生冲突。

    • A method and system for coordinating wireless communication of different waveforms in the same frequency band, is provided, the network including multiple wireless stations of different types operating at the same wireless frequency band but at different waveform formats. Channel bandwidth is allocated by scanning all available channels in the frequency band to detect available channels. When the number of detected available channels is not less than the number of wireless station types, then scheduling and transmitting beacon periods for the different types of wireless stations to different available channels, wherein each type of wireless station may have a dedicated available channel period for wireless communication in parallel with other types of wireless stations.
    • 提供了一种用于协调相同频带中不同波形的无线通信的方法和系统,该网络包括在相同无线频带但不同波形格式下操作的不同类型的多个无线站。 通过扫描频段中的所有可用信道来分配信道带宽,以检测可用信道。 当检测到的可用信道的数量不小于无线站类型的数量时,则调度和发送用于不同类型的无线站的信标周期到不同的可用信道,其中每种类型的无线站可以具有专用的可用信道周期 无线通信与其他类型的无线站并行。
