1. A method, performed in a radio node, of assigning resources for device-to-device discovery signalling, the method comprising:

  • receiving, from a further radio node, information indicating resources for device-to-device discovery signalling in a cell or cluster defined by the further ratio node;

    assigning resources for device-to-device discovery signalling transmission within an area controlled by the radio node based at least on the indicated resources; and

    transmitting, to wireless devices controlled by the radio node, a message indicating the resources assigned for device-to-device discovery signalling in the cell or cluster defined by the radio node, andthe resources assigned for device-to-device discovery signalling in the cell or cluster defined by the further radio node; and

    wherein any of said device-to-device discovery signalling comprises one or more beacons, each beacon indicating an identity of a Device-to-Device (D2D) device to be discovered by another D2D device.
