摘要： Embodiments herein disclose a method in a radio node (12) for enabling communication between a first communication device (10) and a second communication device (11) over a device-to-device, D2D, connection in a radio communications network (1). The radio node (12) allocates radio resource bands of a carrier band for the D2D connection according to at least a first pattern for frequency hopping. The radio resource bands are used for frequency hopping over the carrier band and are at a respective carrier band edge and/or at the respective carrier band edge plus or minus a margin such that a contiguous bandwidth of radio resources between the radio resource bands is not used by the first pattern. The radio node (12) signals an indication of the allocated radio bands to the first and/or the second communication device (10,11).
