Abstract: A method, apparatus and computer program in which an apparatus exchanges wirelessly information with a public land mobile network. The apparatus detects a wireless device to device discovery initiation instruction from the public land mobile network and responsively: sends one or more wireless discovery signal transmissions for a peer device or to monitor wireless discovery signal transmissions sent by a peer device; and directly communicates wirelessly with a peer device that indicates having received the wireless discovery signal transmission or from which the apparatus has detected a wireless discovery signal transmission in result of the monitoring of wireless discovery signal transmissions.

Abstract: The exemplary embodiments include at least a method and apparatus sending by a second network operator a request to use sub-frames muted by macro cells of a first network operator for use by at least one small cell of the second network operator; receiving information for the use of the muted sub-frames; synchronizing a use of the muted sub-frames; and sending an indication of the synchronized use. In addition, a method and apparatus receiving by a first network operator a request to use sub-frames muted by macro cells of the first network operator for use by at least one small cell of a second network operator; sending information for the use of the muted sub-frames; and receiving an indication of the synchronized use of the muted sub-frames.

Abstract: Systems and techniques for synchronization between in-coverage and out-of coverage user devices. A base station configures in-coverage and out-of coverage synchronization signals and configures user devices to recognize synchronization signals as in-coverage or out-of-coverage. An in-coverage device furnishes an in-coverage synchronization signal upon detection of an out-of coverage signal, and may continue to furnish the signal upon continued detection of an out-of-coverage signal that is not synchronized to the network. An out-of-coverage device may receive and synchronize to an in-coverage signal if available, or an out-of-coverage signal if available, or may generate and transmit its own out-of-coverage signal if no in-coverage or out-of-coverage signal is available. Signals may include rank information to indicate relay sequence information, and user devices may be configured to respond to signals based on the rank information—such as favoring a signal whose rank indicates that the signal represents a lower relay order number.

Abstract translation: 覆盖范围和超出覆盖范围的用户设备之间的同步的系统和技术。 基站配置覆盖范围和超出覆盖范围的同步信号，并配置用户设备，将同步信号识别为覆盖范围或覆盖范围以外。 覆盖内设备在检测到超出覆盖信号时提供覆盖内同步信号，并且可以在继续检测到与网络不同步的覆盖范围外的信号时，继续提供信号。 覆盖范围外的设备可以接收并同步到覆盖范围内的信号（如果有的话），或者覆盖范围不足的信号（如果有的话），或者如果没有覆盖范围或者可以生成和发送自己的覆盖范围外的信号， 覆盖范围外的信号可用。 信号可以包括用于指示中继序列信息的等级信息，并且用户设备可以被配置为基于等级信息来响应信号，例如有利于其等级指示信号表示较低的中继命令号的信号。
