摘要： Methods, systems, and devices are described that provide for D2D synchronization. The methods, systems, and/or devices may include tools and techniques that provide for synchronizing a mobile device based on detection of a reliability alarm. A reliability alarm may be used between mobile devices, which is transmitted and/or received on specific D2D resources. Since the resources are reserved for the reliability alarm, a mobile device which was previously isolated from network synchronization will be able to receive the reliability alarm that a reliable synchronization signal is close when it moves within range of a reliable device. Once a reliability alarm is received the mobile device may free other resources to allow it to receive synchronization signals from the reliable devices. The mobile device may then synchronize with the network based on the received synchronization signals and transmit its own reliability alarm for subsequent isolated devices to use.
摘要翻译： 描述了提供D2D同步的方法，系统和设备。 方法，系统和/或设备可以包括基于可靠性警报的检测来提供用于同步移动设备的工具和技术。 在特定的D2D资源上发送和/或接收的移动设备之间可以使用可靠性警报。 由于资源被保留用于可靠性报警，因此先前与网络同步隔离的移动设备将能够接收到可靠的同步信号在可靠设备的范围内移动时关闭的可靠性报警。 一旦接收到可靠性报警，移动设备就可以释放其它资源，以允许其接收来自可靠设备的同步信号。 然后，移动设备可以基于接收到的同步信号与网络同步，并且为随后的隔离设备发送其自己的可靠性警报以供使用。
