Problems solved by technology

[0006] Because the performance of device discovery is related to the load of device discovery resources, for example, when the load of device discovery resources is heavy, such as the number of sending UEs is too large, the collision of discovery signals may increase and the discovery performance may decrease
However, if the allocation of D2D discovery resources is always assumed to be relatively large, it may lead to waste of resources.

Abstract

The invention discloses a device discovery apparatus and a device discovery method for device-to-device (D2D) communication. The apparatus comprises a receiving module which is used for receiving a resource allocation parameter sent by a network side device and receiving a sending probability indication parameter sent by a network side, wherein the resource allocation parameter allocates periodical resources used for sending a D2D signal; a processing module which is used for determining whether or not to send a D2D signal in the resource cycle of the D2D signal at least according to the sending probability indication parameter, or used for determining a discovery resource cycle used for sending the D2D signal at least according to the sending probability indication parameter; and a sending module which is used for sending the D2D signal in the determined discovery resource cycle used for sending the D2D signal.

Description

technical field [0001] The present invention relates to the communication field, in particular to a device discovery device and method for device-to-device communication. Background technique [0002] In the process of implementing the technical solutions of the embodiments of the present application, the inventors of the present application at least found the following technical problems in the related art: [0003] In the cellular communication system, if the user equipment 1 and the user equipment 2 are relatively close, the traditional cellular communication method based on base station access is obviously not optimal. In fact, with the diversification of mobile communication services, for example, the popularity of applications such as social networking and electronic payment in wireless communication systems, the demand for service transmission between users in close proximity is increasing. Based on this, a device-to-device (D2D, Device-to-Device) communication mode ...
