USER EQUIPMENT, A NETWORK NODE, AND METHODS FOR DEVICE DISCOVERY IN DEVICE-TO-DEVICE (D2D) COMMUNICATIONS IN A WIRELESS TELECOMMUNICATIONS NETWORK
First Claim
1. A method in a first user equipment for adjusting a beacon signal to be detected by at least one second user equipment in a wireless telecommunications network, which beacon signal is transmitted in order to enable an establishment of Device-to-Device, D2D, communication between the first user equipment and the at least one second user equipment,characterized in that the method comprisesdetermining the requirement as a required data transfer rate of the application, and wherein the adjusting is based on the required data transfer rate of the application;
- andadjusting, prior to transmitting the beacon signal, the transmit power of the beacon signal based on a requirement of an application in the first user equipment for which the D2D communication is to be established.

Abstract
A method in a first user equipment for adjusting a beacon signal to be detected by at least one second user equipment in a wireless telecommunications network is provided. The beacon signal is transmitted in order to enable an establishment of Device-to-Device, D2D, communication between the first user equipment and the at least one second user equipment. The method is characterized in that the method comprises adjusting, prior to transmitting the beacon signal, the transmit power of the beacon signal based on a requirement of an application in the first user equipment for which the D2D communication is to be established.
A user equipment, a network node, and a method in a network node for enabling a D2D communication between a first user equipment and at least one second user equipment are also provided.

8. A user equipment for adjusting a beacon signal to be detected by at least one second user equipment in a wireless telecommunications network, which beacon signal is transmitted in order to enable an establishment of Device-to-Device, D2D, communication between the first user equipment and the at least one second user equipment,
characterized in that the user equipment comprises an adjustment unit configured to adjust, prior to the transmission of the beacon signal, the transmit power of the beacon signal based on a requirement of an application in the user equipment for which the D2D communication is to be established wherein the adjustment unit is further configured to determine the requirement as a required data transfer rate of the application, and perform the adjustment based on the required data transfer rate of the application.

15. A method in network node for enabling Device-to-Device, D2D, communication between a first user equipment and at least one second user equipment, which first user equipment is configured to transmit a beacon signal to be detected by the at least one second user equipment,
characterized in that the method comprises receiving information from the first user equipment indicating an application in the first user equipment for which a D2D communication is to be enabled, determining an adjustment of the transmit power of the beacon signal to be transmitted by the first user equipment based on a requirement of the application indicated in the received information, and transmitting information about the determined adjustment to the first user equipment to enable D2D communication, which determined adjustment is to be used by the first user equipment when adjusting the transmit power of the beacon signal prior to transmitting the beacon signal.
-
17. A network node for enabling a Device-to-Device, D2D, communication between a first user equipment and at least one second user equipment, which first user equipment is configured to transmit a beacon signal to be detected by the at least one second user equipment,
characterized in that the network node comprises a transceiving unit configured to receive information from the first user equipment indicating an application in the first user equipment for which a D2D communication is to be enabled, and a determining unit configured to determine an adjustment of the transmit power of the beacon signal to be transmitted by the first user equipment based on a requirement of the application indicated in the received information, wherein the transceiving unit is further configured to transmit information about the determined adjustment to the first user equipment to enable D2D communication, which determined adjustment is to be used by the first user equipment when adjusting the transmit power of the beacon signal prior to transmitting the beacon signal.
