This paper considers a downlink cellular network with two base stations (BSs) powered by harvested energy to cooperatively serve two users. To tackle the problem that BSs are of different energy arrival rates, each transmission frame is divided into two subframes, i.e., in the first subframe, one of the BSs keeps silent for some time to store energy while the other transmits to one of the users, and...
This paper presents the power allocation solution in single link Multi-Input Multi-Output (MIMO) wireless communication systems powered by harvested energy. We first derive the channel capacity with non-causal full information in a finite time horizon, which is shown to be a convex optimization problem. The optimal power allocation can be obtained through Spatial-Temporal Water-Filling (ST-WF) solution,...
