First Claim
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.

Abstract
The present disclosure relates to methods and to a wireless device, 10, 20, for enabling device-to-device communication. In particular the present disclosure relates to a method, performed in a radio node, of assigning resources for direct control signalling. The method comprises receiving, S1, from at least one further radio node, 160, sets of resources for direct control signalling in a respective cell or cluster. The method further comprises assigning, S2, resources for direct control signalling transmission within an area controlled by the radio node based at least on the received sets of resources, and transmitting, S3, to wireless devices controlled by the radio node, a message indicating resources assigned for direct control signalling. The disclosure also relates to the corresponding method in a wireless device and to a radio and to a wireless device implementing the methods, as well as to corresponding computer programs.
