Procedure for the management of radio-electric resources in 5G cellular networks for the reuse of resources in vehicle-to-vehicle, V2V, links in cellular networks containing cellular users, C-UEs, at least one eNodeB or base station responsible for controlling and directing communications to and from the cellular user equipment, C-UEs by means of links within an LTE-A architecture, and V-UE vehicles, comprising the following stages: - Grouping of the V-UEs in clusters based on common characteristics comprising direction, distance and relative speed; - Election for each cluster of a central vehicle or Cluster Head, CH responsible for coordinating communications between the cluster members, V-UEs; - Calculation of the minimum distances required between C-UEs and V2V links to make it possible to reuse radio-electric resources in the two links while ensuring that a Signal-to-Interference plus Noise ratio, SINR, of the C-Ues and the V2V links is above a minimum threshold within the area of coverage of an eNodeB or base station, and creation of C-UE and V-UE to V-UE link pairs, when a pair distance between the CUE and the V-UEs allows to share radio-electric resources; - Calculation, for each created pair, of transmission powers of the links between C-UEs and the eNodeB or base station and of the V2V links based on the previously-calculated pair distance information according to the information that each seeks to transmit,, wherein the quantity of radio-electric resources of the V2V links depends on the type of message that needs to be transmitted; - Application of metaheuristics that enable an efficient solution to be obtained for the allocation and reuse of radio-electric resources wherein the number of created pairs is maximised, and the amount of used radio-electric resources within the area of coverage of an eNodeB or base station is minimised. - Grouping of the V-UEs in clusters based on common characteristics comprising direction, distance and relative speed; - Election for each cluster of a central vehicle or Cluster Head, CH responsible for coordinating communications between the cluster members, V-UEs; - Calculation of the minimum distances required between C-UEs and V2V links to make it possible to reuse radio-electric resources in the two links while ensuring that a Signal-to-Interference plus Noise ratio, SINR, of the C-Ues and the V2V links is above a minimum threshold within the area of coverage of an eNodeB or base station, and creation of C-UE and V-UE to V-UE link pairs, when a pair distance between the CUE and the V-UEs allows to share radio-electric resources; - Calculation, for each created pair, of transmission powers of the links between C-UEs and the eNodeB or base station and of the V2V links based on the previously-calculated pair distance information according to the information that each seeks to transmit,, wherein the quantity of radio-electric resources of the V2V links depends on the type of message that needs to be transmitted; - Application of metaheuristics that enable an efficient solution to be obtained for the allocation and reuse of radio-electric resources wherein the number of created pairs is maximised, and the amount of used radio-electric resources within the area of coverage of an eNodeB or base station is minimised.
