Energy-Efficient Power Allocation in Multitier 5G Networks Using Enhanced Online Learning

Abstract: The multi-tier heterogeneous structure of 5G with dense small cells deployment, relays, and device-to-device (D2D) communications operating in an underlay fashion is envisioned as a potential solution to satisfy the future demand for cellular services. However, efficient power allocation among dense secondary transmitters that maintains quality of service (QoS) for macro (primary) cell users and secondary cell users is a critical challenge for operating such radio. In this paper, we focus on the power allocati… Show more

“…Besides, the work in [22] investigates the resource allocation problem to maximize the system secure capacity for D2D communications underlaying HetNets where each subcarrier can be allocated to at most one user of the same type. On the contrary, the authors in [23] focus on the power allocation problem in multi-tier HetNets by employing a non-cooperative scheme to optimize the individual EE of each small cell BS and each D2D pair.…”

“…Severe interference during downlinking causes degradation in quality of service (QoS) for cell‐edge users and negatively affects overall system capacity. Most previous studies on interference in FC networks have focused on distributed power control methods , various radio resource allocation schemes , cognitive radio resource management strategies using game theory , and beamforming techniques . However, these methods incur substantial signaling overhead and various levels of computational complexity.…”
