摘要：

In this letter, we consider 5G networks with Carrier Aggregation (CA). Our aim is to jointly select Component Carriers (CCs) and allocate Resource Blocks (RBs) such that total user throughput is maximized while user power consumption is minimized and Quality of Service (QoS) requirements are met. We formulate the User Equipment (UE) throughput and power consumption in terms of CC and RB indicators and propose a multi-objective optimization problem. Simulation results show that the proposed scheme outperforms the compared techniques by providing approximately 200mW reduction in power consumption while increasing the throughput by 2.7 times for users under short delay constraint. © 2019 IEEE.
