Energy Efficiency Evaluation in HetNet Uplink Transmission: A Survey

In a wireless system communication, the radio signals are diminished as they travel from side to side from air. HetNet is a precise persuasive methodology for cellular networks to make available the capacity and coverage required to move onward. Heterogeneous elements examples consist of picocells, microcells, femtocells, as well as disseminated antenna systems also remote radio heads, which are famed by their physical size, transmit powers/ coverage areas, propagation characteristics and backhaul. However, as the transmission rate and the power consumption, both dependent on the power control coefficient of FPC, become coupled, energy efficiency analysis of FPC in the uplink is complicated. Different from point-to-point wireless links, energy efficiency analysis for wireless networks is complicated due to the presence of co-channel interference and the need to meet network coverage requirements. This paper provides the survey of energy evaluation in HetNet uplink transmission.
