Classification: CPC H  Y | IPC H

Claim 15:
16. A D2D terminal of a set Ω of pairs of terminals of index n in a coverage of a base station that are candidates for direct communication, referred to as D2D terminals, a channel between two D2D terminals in direct communication being referred as the D2D channel, wherein the D2D terminal comprises:
a non-transitory computer-readable memory storing a lookup table of correspondence between different intervals of values of a utility metric and a list of indices ordered from a minimum index to a maximum index defining a ranking of resources available for reporting an indicator of a state of a D2D channel,
a processing unit configured to calculate a value of the utility metric vn(t) assessing an energy efficiency of the D2D communication of the pair and for determining an index of a transmission resource to be used for reporting an indicator by comparing its value of the utility metric vn(t) with the lookup table,
a transmitter configured to report, to the base station, an indicator via the resource of determined index, and
a receiver configured to receive the indicators reported from other D2D terminals and/or for receiving authorization to transmit from the base station.
