Abstract In this paper, maximizing energy efficiency (EE) through radio resource
allocation for renewable energy powered heterogeneous cellular networks (HetNet) with
energy sharing, is investigated. Our goal is to maximize the network EE, conquer the
instability of renewable energy sources and guarantee the fairness of users during
allocating resources. We define the objective function as a sum weighted EE of all links
in the HetNet. We formulate the resource allocation problem in terms of subcarrier
assignment, power allocation and energy sharing, as a mixed combinatorial and
non-convex optimization problem. We propose an energy efficient resource allocation More >
