Abstract: Various communication systems may benefit from appropriate synchronization signal design. For example, third generation partnership project (3GPP) long term evolution advanced (LTE-A) releases 12 and 13 (Rel 12/13) may benefit from such design for device to device (D2D) communications. In particular, synchronization signals may be designed to benefit proximity services (ProSe)/D2D discovery and communication. A method can include transmitting a cellular synchronization signal on a first resource. The method can also include transmitting a device to device synchronization signal on a second resource. The first resource can be different from the second resource. The cellular synchronization signal and the device to device synchronization signal can share a same base sequence.

Abstract translation: 各种通信系统可能受益于适当的同步信号设计。 例如，第三代合作伙伴计划（3GPP）长期演进（LTE-A）发行版12和13（Rel 12/13）可能受益于设备到设备（D2D）通信的这种设计。 特别地，同步信号可以被设计为有益于邻近服务（ProSe）/ D2D发现和通信。 一种方法可以包括在第一资源上发送蜂窝同步信号。 该方法还可以包括在第二资源上向设备发送设备同步信号。 第一个资源可以不同于第二个资源。 蜂窝同步信号和设备到设备同步信号可以共享相同的基本序列。
