Enabling Technologies and Strategies for Radio Resource Management in Decentralized Heterogeneous Wireless Networks

This paper proposes enabling technologies and strategies for Radio Resource Management (RRM) in decentralized heterogeneous wireless networks. To cope with dynamic variation of user signals' bandwidth in the decentralized RRM, Dynamic Spectrum Control (DSC) is applied to flexibly utilize spot-wise available spectra. Spectrum clipping is further applied as a bandwidth adjustment technique to fit the desired spectrum to available spot-wise spectra. Moreover, real time EXIT analysis is applied to evaluate convergence property of the DSC and spectrum clipping before transmission; thereby the decentralized RRM scheme becomes more reliable and stable one.
