Transmission of device to device sounding reference signals using macrocell communication resources
Abstract:
A first wireless communication user equipment (UE) device transmits a device-to device (D2D) Sounding Reference Signal (SRS) to a second wireless communication (UE) device using microcell communication resources. The second wireless communication (UE) device evaluates the SRS to discover the first wireless communication (UE) device, estimate channel conditions, and/or determine Channel State Information. Information indicative of the CSI is reported to a base station. Based on the reported channel conditions, (D2D) communication resources are scheduled by assigning microcell communication resources to the wireless communication (UE) devices.
Abstract(Chinese):

第一无线通信用户设备（UE）设备使用微小区通信资源向第二无线通信（UE）设备发送设备到设备（D2D）探测参考信号（SRS）。 第二无线通信（UE）设备评估SRS以发现第一无线通信（UE）设备，估计信道条件和/或确定信道状态信息。 向基站报告指示CSI的信息。 基于报告的信道条件，通过向无线通信（UE）设备分配微小区通信资源来调度（D2D）通信资源。
