Device to device operation in out of network coverage

A non-transitory computer readable medium storing a computer program for obtaining resources for device to device (D2D) operation in out-of-network coverage (ONC), the computer program comprising computer program code that, when executed by processing circuitry in a wireless device, causes the wireless device to:

• obtain a first set of resources for performing the D2D operation on at least one licensed carrier;
• obtain a second set of resources for performing the D2D operation on at least one un-licensed carrier;
• attempt to determine a location of the wireless device;
• receive information related to the first and second sets of resources for the D2D operation, wherein the information comprises thresholds of signal measurements performed by the wireless device;
• and
• select one of the first and second sets of resources for the D2D operation based on the signal measurements exceeding or staying below the thresholds, wherein the selecting further comprises selecting the first set of resources responsive to determining the location to be within a coverage area of the at least one licensed carrier and selecting the second set of resources responsive to failing to determine the location, and
• wherein the first set of resources and the second set of resources are obtained by determining at least one of the first and second sets of resources based on following criteria:
• load on carriers;
• the location of the wireless device;
• a priority level or a type of the D2D operation;
• and
• information about a location of possible carrier frequencies in frequency bands.
