发现信号生成和接收
摘要：
描述了针对设备对设备(D2D)发现信号生成以及D2D发现信号的传输和调度的物理层处理和过程。描述了D2D发现信号的检测和测量，D2D信号标识管理以及由无线发射/接收单元(WTRU)针对D2D发现调度监控PDCCH，如可以被配置D2D特定的发射/接收时机模式的WTRU。所述发现信号可以携带针对有关用户和/或服务标识的显式信息的净荷并且可以被映射至物理资源以此去耦合来自下行链路操作的发现信号的发射/接收。WTRU可以测量D2D发现信号质量并且报告给网络。
摘要（英）：

Physical layer processing and procedures for device-to-device (D2D) discovery signal generation and transmission and scheduling of D2D discovery signals are described. Detection and measurement of a D2D discovery signal, D2D signal identity management, and monitoring by a wireless transmit/receive unit (WTRU) of PDCCH for D2D discovery scheduling is described, as is a WTRU that may be configured with a D2D-specific transmission/reception opportunity pattern. The discovery signal may carry a payload for explicit information about user and/or service identity, and may be mapped to physical resources in such a way as to decouple transmission/reception of the discovery signal from downlink operations. A WTRU may measure a D2D discovery signal quality and report to the network.
