Elemento de red y procedimiento para coordinar el uso de recursos radio entre redes de acceso radio

Coordination of the use of radio resource between a first Radio Access Network (RAN) and a second RAN is provided, each RAN being configured to communicate over the same predefined bandwidth range. A first priority associated with traffic to be carried over the first RAN and a second priority associated with traffic to be carried over the second RAN are determined. A first portion of the radio resource comprising one or more first bandwidth segments is assigned to the first RAN and a second portion of the radio resource comprising a plurality of second bandwidth segments is assigned to the second RAN, based on the first and second priorities. The first portion is indicated to a first RAN scheduler and/or the second portion is indicated to a second RAN scheduler. At least one first bandwidth segment is assigned between two of the second bandwidth segments.
