A daptive radio resource allocation in a cellular and multiuser OFDMA-Based relay network is considered in this paper. We solve the problem with the objective function for minimizing total transmitted power and the constraints on the relay and user data rates. We have studied adaptive subframe and subcarrier allocation and greedy bit loading in a cellular scenario. Users are distributed randomly and...
In this paper, an adaptive resource allocation (subframe, subcarrier, bit and power allocation) in a cellular multiuser OFDMA-based relay network is considered. We have studied a margin adaptive problem that satisfies link rate requirements with minimum total base station and relay stations power for a fixed set of discrete modulation levels. This problem has been solved by various optimization techniques...
