determining configuration information indicating discovery resources for device discovery, 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; and

sending the configuration information.

An embodiment of the present disclosure further provides an apparatus for sending device discovery signals, which includes:

a first communication unit arranged to receive configuration information indicating discovery resources for device discovery;

a central processing unit arranged to determine, based on the configuration information, 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 by the central processing unit in a manner of time division multiplexing and/or frequency division multiplexing; and

a second communication unit arranged to send the device discovery signals on the determined discovery resource elements.

An embodiment of the present disclosure further provides a user equipment including the apparatus for sending device discovery signals described above.
