摘要
An energy-efficient framework for active transmission in OFDMA-based long-range wireless networks is disclosed. This frame-work is based on using energy-aware metrics for resource allocation and link adaptation. By casting the optimal energy-efficient resource allocation problem as utility-based optimization problem, low-complexity utility-based resource allocation schemes developed here can be applied to reduce the complexity of resource allocation decisions.
