    • A terminal device for use in a wireless telecommunications system comprising a plurality of terminal devices operable to communicate with one another in a device-to-device manner, wherein the terminal device comprises a controller unit and a transceiver unit configured to operate together to cause the terminal device to determine a transmission power level to use for device-to-device transmissions from the terminal device to restrict the number of the other terminal devices able to receive the device-to-device transmissions to a restricted subset of the other terminal devices, and to transmit device-to-device communications using the determined transmission power level. The terminal device may determine the transmission power itself or from control signalling reads received from network infrastructure equipment, such as a base station or roadside unit.
    • 一种在无线电信系统中使用的终端设备,包括可以以设备到设备的方式彼此通信的多个终端设备,其中所述终端设备包括控制器单元和收发器单元,其被配置为一起操作以使 终端设备以确定要用于来自终端设备的设备到设备传输的发射功率电平,以将能够接收设备到设备传输的其他终端设备的数量限制到其他终端设备的受限子集, 并且使用所确定的发射功率电平来发送设备到设备通信。 终端设备可以自己确定发射功率,或者从诸如基站或路边单元的网络基础设施设备接收的控制信令读取来确定发射功率。
