Abstract: To address the challenge of radio spectrum scarcity and the more-and-more challenging requirements of emerging mobile applications, the use of multi-band systems is a promising solution for future cellular networks. In this seminar, we present a new measure of energy efficiency, and we address the problem of joint optimization of resource allocation in sub-6 GHz, millimeter wave and terahertz coexistence networks. The problem formulated is a nonlinear mixed-integer programming problem and it turns out to be an NP-hard problem. The objective is to maximize the system energy efficiency while respecting the QoS (throughput and signal-to-interference plus noise) constraints of each user. To find a solution within a reasonable amount of time, the problem is divided into two sub-problems to be solved iteratively. First, we solve the joint problem of user-base station association and channel allocation. Secondly, the power allocation sub-problem is solved. Next, we propose a multi-agent resource allocation solution based on deep reinforcement learning. Simulation results reveal the effectiveness of the proposed iterative and reinforcement-learning solutions compared to other solutions and illustrate the impact of multi-band communications on improving the system energy efficiency .
