Abstract

According to a first aspect of embodiments herein, the object is achieved by a method in a base station for handling a process of discovering a candidate user equipment for Device to Device, D2D, communication in a cell. The cell is served by the base station. The base station divides (200) the cell into a number of regions. The base station then assigns (201) to each one out of the number of regions, a channel resource for use in the region. The channel resource is for sending beacon signals in the process of discovering the D2D candidate user equipment.
