  Abstract: In this paper, we pursue a unified study on smart grid and coordinated multipoint (CoMP)-enabled wireless communication by investigating a new joint communication and energy cooperation approach. We consider a practical CoMP system with clustered multiple-antenna base stations (BSs) cooperatively communicating with multiple single-antenna mobile terminals (MTs), where each BS is equipped with local renewable energy generators to supply power, as well as a smart meter to enable two-way energy flow with the grid. We propose a new  energy cooperation  paradigm, where a group of BSs dynamically shares their renewable energy for more efficient operation via locally injecting/drawing power to/from an aggregator with a zero effective sum energy exchanged. Under this new energy cooperation model, we consider the downlink transmission in one CoMP cluster with cooperative zero-forcing (ZF)-based precoding at the BSs. We maximize the weighted sum rate for all MTs by jointly optimizing the transmit power allocations at cooperative BSs and their exchanged energy amounts subject to a new type of power constraints featuring energy cooperation among BSs with practical loss ratios. Our new setup with BSs' energy cooperation generalizes the conventional CoMP transmit optimization under BSs' sum-power or individual-power constraints. It is shown that, with energy cooperation, the optimal throughput is achieved when all BSs transmit with all of their available power, which is different from the conventional CoMP schemes without energy cooperation where BSs' individual power constraints may not all be tight at the same time. This result implies that some harvested energy may be wasted with no use in the conventional setup due to the lack of energy sharing among BSs, whereas the total energy harvested at all BSs is efficiently utilized for throughput maximization with the proposed energy cooperation, thus leading to a new  energy cooperation gain . Finally, we validate our results by simulations under various practical setups and show that the proposed joint communication and energy cooperation scheme substantially improves the downlink throughput of CoMP systems powered by smart grid and renewable energy, as compared with other suboptimal designs without communication and/or energy cooperation.
