The energy efficiency and packet delay tradeoffs in long term evolution-advanced （LTE-A） systems are investigated.Analytical expressions are derived to explain the relation of energy efficiency to mean packet delay,arrival rate and component carrier （CC） configurations,from the theoretical respectiv...
