    • An application data synchronization system may include a data storage system and a data synchronization module. The data storage system may store the identity of entities and, for each entity, the identity of a group of cellular communication devices used by the entity and at least one application that has been delivered to at least two of the cellular communication devices in the group. The data synchronization module may detect that an application has changed data while operating in one of the cellular communication devices. The data synchronization module may consult the data storage system to determine whether the application was also delivered to one or more other cellular communication devices within the same entity group and, if so, cause the changed data to be propagated to the one or more other cellular communication devices within the same entity group.
    • 应用数据同步系统可以包括数据存储系统和数据同步模块。 数据存储系统可以存储实体的身份,并且对于每个实体,该实体使用的一组蜂窝通信设备的标识和至少已经传送到该组中的至少两个蜂窝通信设备的应用 。 数据同步模块可以在蜂窝通信设备之一中操作时检测到应用已经改变了数据。 数据同步模块可以参考数据存储系统以确定应用程序是否也被递送到同一实体组内的一个或多个其他蜂窝通信设备,如果是,则使改变的数据传播到一个或多个其他蜂窝 同一实体组内的通信设备。

    • One method of estimating timing and frequency information of a payload transmitted through two or more frequency separated channels combines training fields from preambles from the two or more frequency separated channels to construct combined values that may be used to estimate the frequency and timing information. In one embodiment, the combined values may be determined by combining self-correlated training fields from the frequency separated channels. Another method of estimating the timing and frequency information selects the training fields from the preamble of one of the frequency separated channels based upon a signal quality metric. In another embodiment, the selection of the training fields based upon a signal quality metric may be biased to favor a particular channel.
    • 估计通过两个或多个频率分离的信道传输的有效负载的定时和频率信息的一种方法组合来自两个或更多个频率分离信道的前导码的训练场,以构建可用于估计频率和定时信息的组合值。 在一个实施例中,可以通过组合来自频率分离的信道的自相关训练场来确定组合值。 估计定时和频率信息的另一种方法是基于信号质量度量从频率分离信道之一的前同步码中选择训练场。 在另一个实施例中,基于信号质量度量的训练场的选择可能偏向于有利于特定频道。
