摘要

The present invention relates to a method for improving device-to-device proximity detection and / or device-to-device communication between a first user equipment and a second user equipment, the first user equipment and The second user equipment supports the use of a device-to-device mode (D2D mode) and provides for device-to-device proximity detection and / or device-to-device communication between the first and second user equipment. Using the device-to-device mode to perform a discovery procedure between the first and second user equipment, wherein at least the first user equipment includes a core network and an access network And the access network of the mobile communication network includes a base station entity and a first user. The first frequency or frequency band is used to receive the first control data by the device, the first control data is transmitted by the base station entity, and the second user device receives the second control data. A second frequency or frequency band is used for the method, and the method includes the following steps, in which the base station entity uses the first discovery resource configuration information as part of the first control data And second discovery resource configuration information, wherein the first discovery resource configuration information indicates that the first radio interface resource can be used for discovery involving the first user equipment, In the second discovery resource configuration information, the second radio interface resource relates to the second user apparatus. In a second step after the first step, the first user equipment (20) indicates that it can be used for discovery by using the second radio interface resource The second discovery resource configuration information is used to perform the discovery procedure for the second user apparatus.
