Patent ID: 8600394

Claim:
A method for assigning frequency subbands to a plurality of interfering nodes in a wireless communication network, wherein a number of subbands assigned to a node depends from the interference condition at the node, wherein as the node faces less interference it is assigned more subbands, wherein assigning subbands to interfering nodes comprises: (a) for each of the plurality of interfering nodes, selecting a frequency subband which causes a minimum decrease in subband usage in the network, (b) for each frequency subband, determining one or more of the interfering nodes, which face less or no interference with one or more of the remaining frequency subbands, and selecting one or more of the interference nodes which cause a minimum decrease in subband usage in a network, and (c) assigning the respective remaining one or more frequency subbands to the selected interfering nodes, and wherein subband usage is defined on the basis of the number of nodes interfering with a chosen node to which a specific subband is assigned.
