MANAGING RESOURCES FOR DEVICE-TO-DEVICE D2D DISCOVERY IN AN AD-HOC RADIO COMMUNICATION NETWORK

摘要

A method and a radio node (110) for managing resources for Device-to- Device discovery in an ad-hoc radio communicationnetworkare disclosed. The radio node (110) measures, on an amount of resources, received power to obtain values of received power. The values of received power include a respective value of received power for each resource of the amount of resources. The received power includes powerof any existing beacon signals received from oneor more of the further radio nodes (120, 130, 140).The radio node (110) selects at least one resource out of the amount of resources. The respective value of received power for the selected at least one resource is among the least of the obtained respective values of received power. The radio node (110) broadcasts, to the further radio nodes (120, 130, 140), a beacon signal on the selected at least one resource, wherein the beacon signal includes one or more of the values of received power.
