    • Methods and apparatus related to supporting rapid synchronization between groups of wireless communications devices are described. Described methods and apparatus are well suited for use in peer to peer wireless communications systems in which a plurality of ad hoc peer to peer networks may be formed, each ad hoc network operating with its own notion of time. As two groups of devices, having different notions of time, come within proximity of one another, a wireless communications device of a first group detects the presence of a member of a second group. The wireless device determines that network timing re-synchronization is to be performed by one of the first and second groups and transmits a re-synchronization alert signal on a dedicated resource. Subsequently, the wireless device transmits a timing synchronization signal in accordance with new timing. Intended devices, which detect the alert signal and timing synchronization signal, adjust their internal timing.
    • 描述了支持无线通信设备组之间的快速同步的方法和装置。 描述的方法和装置非常适合用于可以形成多个自组织对等网络的对等无线通信系统,每个自组织网络以其自己的时间概念运行。 作为具有不同时间概念的两组设备彼此接近,第一组的无线通信设备检测第二组的成员的存在。 无线设备确定网络定时重新同步将由第一组和第二组之一执行,并在专用资源上发送重新同步报警信号。 随后,无线设备根据新的定时发送定时同步信号。 用于检测报警信号和定时同步信号的设备调整其内部时序。
