METHOD FOR ASSIGNING FREQUENCY SUBBANDS TO A PLURALITY OF INTERFERING NODES IN A WIRELESS COMMUNICATION NETWORK, CONTROLLER FOR A WIRELESS COMMUNICATION NETWORK AND WIRELESS COMMUNICATION NETWORK

摘要

PURPOSE: A sub-band frequency allocation method, wireless communication network, and control unit thereof are provided to allocate much more sub-bands to specific nodes by using a resource partitioning approach method. CONSTITUTION: One sub-band is respectively allocated to nodes(A~F). The additional sub-band is not allocated to nodes(A~C) due to interference. The additional sub-band is able to be allocated to nodes(D,E). A second sub-band which is not used by the node(A) is allocated to the node(D) by additionally allocating to an original sub-band. Nodes(D,C) are able to be allocated when interference is not founded between the nodes.
