    • This disclosure is directed to a dynamic certification system. In general, a device may transmit a request message to a cloud spectrum broker/licensed shared access (CSB/LSA) controller requesting certification for operation in shared wireless spectrum. The device may then receive a response message containing information on available certifications for operating in the shared wireless spectrum. If at least one available certification is determined to be usable by the device, then, depending on the system configuration, the device may claim an available certification (e.g., by obtaining an electronic certification document, token, etc.) or may request to use an available certificate, which may be confirmed by the CSB/LSA controller. The device may then operate in the shared wireless spectrum based on conditions set forth in the certificate.
    • 本公开涉及动态认证系统。 通常,设备可以向云频谱代理/许可共享访问(CSB / LSA)控制器发送请求消息,请求认证以在共享无线频谱中进行操作。 然后,设备可以接收包含关于在共享无线频谱中操作的可用认证的信息的响应消息。 如果至少一个可用认证被确定为可由设备使用,则根据系统配置,设备可以要求可用的认证(例如,通过获得电子认证文档,令牌等)或者可以请求使用 可用证书,可以由CSB / LSA控制器确认。 然后,设备可以基于证书中所陈述的条件在共享无线频谱中操作。

    • Methods and apparatus that enable one or more wireless networks to minimize inter-cellular interference (ICI) at a receiver. In one embodiment, the network comprises an OFDM-based cellular network, and the method comprises utilizing a priori knowledge of non-data portions of signals from multiple base stations in order to schedule transmissions. In one variant, these non-data portions comprise pilot tones; the pilot tones can be scheduled onto various time-frequency resources of the network so as to minimize ICI. The mobility context of the receiver can also be used as a basis for dynamically adjusting the pilot tone density. In another variant, preceding (e.g., Tomlinson-Harashima precoding) can be applied to "shape" the non-data portions of the transmitted signals so as to mitigate ICI. In yet other variants, frame preambles and learning sequences are used as the basis for invoking selective transmission time shifts across the potentially interfering base stations so as to minimize ICI.
    • 使得一个或多个无线网络能够最小化接收器处的蜂窝间干扰(ICI)的方法和设备。 在一个实施例中,网络包括基于OFDM的蜂窝网络,并且该方法包括利用来自多个基站的信号的非数据部分的先验知识,以便调度传输。 在一个变体中,这些非数据部分包括导频音; 可以将导频音调度到网络的各种时频资源上,以使ICI最小化。 接收机的移动环境也可以用作动态调节导频音密度的基础。 在另一个变型中,前面的(例如Tomlinson-Harashima预编码)可以应用于“形状” 传输信号的非数据部分以减轻ICI。 在其他变体中,使用帧前导码和学习序列作为调用潜在干扰基站上的选择性传输时移的基础,以使ICI最小化。
