IMT-advanced
Abstract— 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.
