Control apparatus and method for wireless communication system supporting cognitive radio

A first apparatus for a wireless communication system, comprising:

• a processing circuitry configured to:
• transmit an access request for a spectrum resource to an apparatus managing the first apparatus;
• receive available spectrum resource information about an available spectrum resource for the first apparatus, wherein the available spectrum resource information is provided in response to the access request and on the basis of routing information determined by the apparatus, wherein the first apparatus is capable of communicating with a second apparatus using the available spectrum resource;
• and
• receive a reconfiguration request from the apparatus, wherein the reconfiguration request comprises routing information or a time configuration of another access request to be used by the first apparatus.

A second apparatus for a wireless communication system comprising:

• a processing circuitry configured to:
• determine a reconfiguration request for a first apparatus managed by the second apparatus, wherein the reconfiguration request comprises routing information or a time configuration of an access request to be used by the first apparatus, wherein the access request is used for a spectrum resource for accessing an apparatus managing the first apparatus;
• and
• communicating with the first apparatus using an available spectrum resource indicated by available spectrum resource information provided by the apparatus, wherein the available spectrum resource information is provided in response to the access request and on the basis of routing information determined by the apparatus.
