In this paper, by adjusting user-cell association, we investigate an energy minimization problem in the macro-relay network where the rate requirements of all users are strictly guaranteed. We consider the interference between the macro and relay stations and capture the strength of the interference by the interference factor. Firstly, an integer optimization problem is formulated that is NP-hard...
In this paper, we investigate the energy efficiency problem in macro-relay network. Considering users with different locations and rate requirements, our objective is to serve all users with strict rate guarantee and meanwhile minimize the total energy consumption of the network. First, we formulate an integer optimization problem with the variables as station-user connections. Then we analyze the...
In this paper, an energy minimization problem for users with heterogeneous locations and rate requirements in the macro-relay network is considered, in which the rate requirements of all users are strictly guaranteed and meanwhile the total energy consumption of the network is minimized. First, the energy minimization problem is formulated as an integer optimization problem, which is similar to the...
