In this chapter, we investigate a wireless powered communication network (WPCN) comprised of a power beacon that broadcasts radio frequency (RF) energy to a set of energy harvesting (EH) transmitters equipped with unlimited batteries, which use the harvested energy to transmit information back to the power-beacon in a non-orthogonal multiple access fashion. For this network, we propose a communication scheme which achieves the capacity region. Moreover, we show that the capacity region of the considered WPCN converges to the capacity region of its corresponding non-EH multiple access network, where the non-EH transmitters have specific average power constraints.
