In this paper, an new algorithm for frequency channel allocation in cellular mobile systems is proposed and examined in comparison with a dynamic load balancing strategy for channel assignment using selective borrowing in cellular mobile environment and a new adaptive channel assignment algorithm in cellular mobile system. When making a borrowing decision, the states of the co-channel cells of a potential...
A novel practical low-complexity multicell orthogonal frequency-division multiple access (OFDMA) downlink channel-assignment method that uses a graphic framework is proposed in this paper. Our solution consists of two phases: 1) a coarse-scale intercell interference (ICI) management scheme and 2) a fine-scale channel-aware resource-allocation scheme. In the first phase, state-of-the-art ICI management...
A novel, practical and low-complexity multi-cell OFDMA downlink channel assignment method using a graph- based approach is proposed in this work. The inter-cell interference (ICI) information is obtained through inference from the diversity set of mobile stations (MSs) and presented in the form of an interference graph. The proposed downlink channel assignment method consists of two phases. The task...
