This paper investigates and proposes a framework for the efficient integration of functionalities for dynamic spectrum use (e.g., spectrum aggregation) and cooperative radio resource management (RRM) in the scope of IMT-Advanced (IMT-A) candidate systems. The envisaged technical solution is based on a joint centralized and distributed approach for both intra-and inter-operator scenarios. Spectrum assignment decisions benefit from a distributed approach that can be realized by the pooling of resources at higher layers together. The paper investigates the possible interworking between the two techniques for the benefits of achieving higher performance and capacity gains. Based on the proposed framework, operators will be able to demand portions of the spectrum for a certain time period and coordinate this action with the actual network loads. The framework is described in terms of functionalities, physical entities, and mutual interactions. The proposed integrated framework can reduce the CAPEX and OPEX during the deployment of IMT-A systems.
