In this paper, we study the energy-efficient user access control (UAC) based on resource allocation (RA) in heterogeneous cellular networks (HCNs) with the required downlink data rate under non-ideal power amplifiers (PAs) and circuit power. It is proved that the energy consumption minimization is achieved when the typical user accesses only one base station (BS), while the other BSs remain in idle...
Resource allocation in Orthogonal Frequency Division Multiplexing (OFDM) system with mixed traffic is studied in this paper. The sub-carriers and power of a base station (BS) are allocated to users to maximize energy efficiency, which is measured by utility per Watt. We model the allocation of sub- carriers and power as a mixed integer nonlinear programming (MINLP) problem, which is computationally...
Energy efficiency is becoming more and more important to the development of wireless communication. In this paper, we study energy-efficient resource allocation in an Orthogonal Frequency Division Multiplexing (OFDM) system with mixed traffic. Considering both the energy efficiency and spectral efficiency, we model the allocation of sub-carriers and power as a mixed integer nonlinear programming (MINLP)...
