- the first discovery signal may also be sent by means of a broadcast, which is similar to the foregoing embodiment 3-7, and details are not described herein again.
- the above embodiment has been described by taking the communication from the UE to the UE as an example.
- the case of the communication from the base station to the base station is similar to that of the above embodiment, and only the cases similar to the embodiments 10 and 13 are exemplified herein.
- Figure 11 is a flow chart showing the method of device-to-device synchronization in Embodiment 14 of the present invention. As shown in Figure 11, cell discovery and synchronization between the base station and the base station. Similar to the embodiment 10 shown in FIG. 7, it will not be described again here.
- Figure 12 is a flow chart showing the method of device-to-device synchronization in Embodiment 15 of the present invention. As shown in Figure 12, cell discovery and synchronization between the base station and the base station. Similar to the embodiment 13 shown in FIG. 10, details are not described herein again.
- the embodiment of the present invention further provides a computer readable program, wherein when the program is executed in a signaling configuration apparatus, the program causes the computer to execute the signaling configuration method described in Embodiment 1 in the signaling configuration apparatus.
- the embodiment of the present invention further provides a storage medium storing a computer readable program, wherein the computer readable program causes the computer to execute the signaling configuration method described in Embodiment 1 in a signaling configuration apparatus.
- Embodiment 1 of the present invention also provides a computer readable program, wherein when the program is executed in a device-to-device synchronization device, the program causes a computer to execute Embodiment 3 in the device-to-device synchronization device or 6.
- the method of device-to-device discovery as described in 10 or 13.
- Embodiments of the present invention also provide a storage medium storing a computer readable program, wherein the computer readable program causes a computer to execute the device of Embodiment 3 or 6, or 10 or 13 in a device-to-device synchronization device The method of discovery to the device.
- the above apparatus and method of the present invention may be implemented by hardware, or may be implemented by hardware in combination with software.
- the present invention relates to a computer readable program that, when executed by a logic component, enables the logic component to implement the apparatus or components described above, or to cause the logic component to implement the various methods described above Or steps.
- Logic components such as field programmable logic components, microprocessors, processors used in computers, and the like.
- the present invention also relates to a storage medium for storing the above program, such as a hard disk, a magnetic disk, an optical disk, a DVD, a flash memory, or the like.
