A method assigning frequency bands on a cellular network including plural network nodes each configured to activate transmission links between pairs of corresponding network nodes to exchange traffic. The method includes, in response to assessment of a new transmission link to be activated between first and second network nodes: retrieving an indication of coordinates of first and second network nodes within a geographical area; retrieving an indication of resource sharing clusters, of the cellular network, each including a group of transmission links considered to potentially cause transmission collisions; selecting a set of the resource sharing clusters according to a comparison of coordinates of the first network node with coordinates of the network nodes corresponding to the transmission links of the resource sharing clusters; if the selected set of resource sharing clusters is not empty, carrying out operations including: activating a new transmission link by exploiting an assigned frequency band.

Method and system for limiting collisions in cellular networks

A cellular network comprising one or more user transceiver stations located within a first coverage area and that are each configured to provide radio coverage over a corresponding second coverage area by exploiting a selected frequency band among a respective set of frequency bands. When a user equipment within one first coverage area of requests to exchange user traffic, the cellular network selects a group of candidate user transceiver stations located within the first coverage area based on the position of the user equipment within the first coverage area; select a group of candidate frequency bands among sets of frequency bands of the user transceiver stations located within said one first coverage area; and allow the user equipment to exchange user traffic with one or more selected user transceiver stations exploiting a selected frequency band.

Multi-band cellular network with control plane decoupled from user plane

A cellular network is provided. The cellular network includes a plurality of control plane transceiver stations, each one configured to provide radio coverage over a corresponding first coverage area for allowing user equipment within said first coverage area to exchange signaling traffic with the control plane transceiver station. For each control plane transceiver station, the cellular network further comprises one or more hybrid transceiver stations located within the corresponding first coverage area. Each hybrid transceiver station is configured to be switched between: a) a user operation modality that allows user equipment within said user coverage area to exchange user traffic with the hybrid transceiver station, and b) a control operation modality that provides radio coverage over a corresponding control coverage area for allowing user equipment within said control coverage area to exchange at least signaling traffic with the hybrid transceiver station.
