Summary

In this chapter, we first provide an overview of the frequency planning schemes in wireless networks. Next, we consider the DCA scheme in OFDMA networks and describe a semi-distributed radio resource control scheme, where DCA is realized at both the RNC and BSs. To capture the multiuser diversity in a multicell broadband environment, the RNC coordinates intercell interference over BSs at the super-frame level, where each BS makes its channel assignment decision on the frame level based on the users' channel as well as traffic conditions. As a result, the radio resources are always assigned to the user with the highest utility value. Two suboptimal channel allocation algorithms are presented for the RNC and BSs, respectively. The spectrum efficiency of multicell OFDMA systems under different cell/sector configurations is evaluated.
