摘要

The present disclosure discloses a method, apparatus, device and system for sending device discovery signals. The method includes: acquiring configuration information indicating discovery resources for device discovery; determining discovery resource elements for sending the device discovery signals in a discovery resource period indicated by the configuration information, the discovery resource elements being obtained by dividing radio resources in the discovery resource period in a manner of time division multiplexing and/or frequency division multiplexing; and sending the device discovery signals on the determined discovery resource elements.

說明書

a sending unit arranged to send the configuration information, the configuration information indicating the periodic discovery resources, discovery resource elements being obtained by dividing radio resources in the discovery resource period in a manner of time division multiplexing and/or frequency division multiplexing, and the discovery resource elements being used by a user equipment to send the device discovery signals.

An embodiment of the present disclosure further provides a network side device, which is the apparatus for sending device discovery signals described above.

An embodiment of the present disclosure further provides a system for sending device discovery signals, which includes the user equipment and network side device of a cellular network described above.

The technical schemes of the embodiments of the present disclosure solve the half-duplex problem in the device discovery of device-to-device communication systems so as to avoid the problem that the UEs cannot discover each other when sending and monitoring the discovery signals at the same time, and have strong versatility.
