A simple network-power-saving resource allocation method for OFDMA cellular networks with multiple relays
General signal model for orthogonal-frequency-division multiple access cellular networks with multiple amplify-and-forward relays has been introduced. An optimization problem minimizing network power is formulated to allocate subchannels and to design relay processing, and it is simplified to achieve a suboptimal solution. Numerical results show that the proposed resource allocation method achieves network power reduction and performance improvement.
