Method for configuring radio resources (121, 161, 162, 171, 172) distributed in a plurality of communication nodes (12, 16, 17) of a communication network comprising a so-called backhaul subnetwork and a so-called fronthaul user network, the fronthaul subnetwork being a wireless network, each communication node (12, 16, 17) comprising one or more radio resources (121, 161, 162, 171, 172), the method being executed in a communication node (12, 16, 17) of said communication network, and being characterised in that it comprises: - collecting, for each of said radio resources (121, 161, 162, 171, 172), configuration parameters, and at least one parameter representing a reception level of a signal sent or received by this radio resource, - detecting, from said collected radio-resource configuration parameters, and from at least one of said parameters representing a reception level, a common configuration parameter value and a proximity between a radio resource of a first communication node and a radio resource of a second communication node from said plurality of communication nodes (12, 16, 17), of such a nature as to cause interference in the communications between the first and second communication nodes (12, 16, 17), said proximity being detected as soon as the reception power level of a signal sent by the radio resource of the first communication node and received by the radio resource of the second communication node or of a signal sent by the radio resource of the second communication node and received by the radio resource of the first communication node is above a predetermined threshold, said radio resources (121, 171) of the first and second communication nodes being configured for implementing transmissions by a wireless link in the so-called backhaul subnetwork, - configuring at least the radio resource of the second communication node having a common configuration parameter value with a new configuration, said value of said common configuration parameter being absent from the new configuration and said second radio resource being configured for implementing transmissions in the fronthaul subnetwork after said configuration step, - detecting at least one cable link between the first and second communication nodes able to be substituted for the wireless link for communications in the backhaul subnetwork, so that said communications made by the wireless link between the first and second communication nodes are made by the cable link after the reconfiguration step. - collecting, for each of said radio resources (121, 161, 162, 171, 172), configuration parameters, and at least one parameter representing a reception level of a signal sent or received by this radio resource, - detecting, from said collected radio-resource configuration parameters, and from at least one of said parameters representing a reception level, a common configuration parameter value and a proximity between a radio resource of a first communication node and a radio resource of a second communication node from said plurality of communication nodes (12, 16, 17), of such a nature as to cause interference in the communications between the first and second communication nodes (12, 16, 17), said proximity being detected as soon as the reception power level of a signal sent by the radio resource of the first communication node and received by the radio resource of the second communication node or of a signal sent by the radio resource of the second communication node and received by the radio resource of the first communication node is above a predetermined threshold, said radio resources (121, 171) of the first and second communication nodes being configured for implementing transmissions by a wireless link in the so-called backhaul subnetwork, - configuring at least the radio resource of the second communication node having a common configuration parameter value with a new configuration, said value of said common configuration parameter being absent from the new configuration and said second radio resource being configured for implementing transmissions in the fronthaul subnetwork after said configuration step, - detecting at least one cable link between the first and second communication nodes able to be substituted for the wireless link for communications in the backhaul subnetwork, so that said communications made by the wireless link between the first and second communication nodes are made by the cable link after the reconfiguration step.
