%X <p>In order to improve the average user utility of energy harvesting in energy broadcasting system with massive antennas, the maximum ratio transmission precoder was employed. Considering the single energy source scenario, the optimal power allocation scheme is first derived with aid of advantage of the characteristics of massive antennas. To exploit the inter-cell interference, a cooperative energy transfer scheme was proposed in multiple energy sources scenario, and the optimal power allocation for cooperative energy transfer was deduced correspondingly. Simulations indicate that the performance with the optimal power allocation is better than that with equal power allocation in single energy source scenario, and the cooperative energy transfer outperforms the non-cooperative energy transfer in multiple energy sources scenario.</p>
