Abstract
For the downlink of OFDMA network without Quality of Service (QoS) provision, it has been proved that the network energy efficiency (EE) achieved by best Channel Quality Indicator (CQI) subcarrier allocation scheme is in close proximity to the optimal EE. However, for the downlink of OFDMA network with the provision of QoS, the existing algorithms directly assigning subcarriers have the problem of high complexity. This paper proposed a new subcarrier allocation algorithm by readjusting the subcarrier allocation obtained via the allocation principle of best CQI. The proposed algorithm attempts to maximize the EE of network, and at the meanwhile reduce computational complexity. Simulation experiments indicate that the proposed algorithm significantly reduces computational complexity and achieves nearly the same EE as the optimal solution.
