In heterogeneous networks (HetNet), power control at a Home eNodeB (HeNB) is a major issue in reducing co-channel interference where the fairness among HetNet users should be taken into account. In this letter, we formulate an equation that aims to maximize the minimum user rate among macro users to determine a proper target rate. Based on the determined target rate, we obtain the transmit power of...
In this paper, we formulate the problem to guarantee a max-min fairness for multicast in an orthogonal frequency division multiple access (OFDMA)-based heterogeneous network (Het-Net) by managing the power allocation at base stations (BSs) of coexisting macrocell and picocells, where different common messages are, respectively, transmitted from BSs to their served user equipments (UEs) in the same...
