Abstract: A method for allocating transmission resources to at least one terminal of a set of D2D terminals for direct communication implemented by a cellular access network having a base station. The method includes, for a transmission interval: calculating, by each transmitter terminal of a D2D pair, of a value of a utility metric indicating an energy efficiency of the D2D communication of the pair; determining a transmission resource index to be used for the relaying of an indicator by each transmitter terminal of a D2D pair by comparing its value of the utility metric with the table of correspondence; relaying an indicator, by each transmitter terminal of pair, via the index resource representing the value of its utility metric; and determining, by the base station an optimum D2D transmitter terminal, of which the resource for relaying the indicator has the minimum order index, for the allocation of resources.

Abstract: A method for allocating transmission resources to at least one terminal of a set of D2D terminals available for direct communication implemented by a cellular access network having a base station. The base station has knowledge of a statistic relating to the state of the D2D channels. The method includes, for a transmission interval: determination, by the base station, of a subset among different subsets of D2D terminals of the set that statistically minimizes a utility function; determination, by each D2D terminal of subset, of a minimum power and a maximum throughput which minimize its utility metric; and determination, by the base station, of a D2D terminal among the D2D terminals of subset, of which the utility function applied to its minimum power and its maximum throughput is minimal, in order to allocate to the terminal spectral resources for transmission during the transmission interval.
