- Abstract
- In this paper, we propose an online power allocation (PA) scheme to maximize the time averaged sum rate for multiple downlink receivers with energy harvesting transmitter. The transmitter uses non-orthogonal multiple access (NOMA) to transmit data to multiple users. For fairness, we impose a power order constraint on the power allocation among the users. The decisions of total transmit power and power allocation for different users in a given time slot are obtained with the help of Lyapunov optimization technique. The proposed scheme does not require any statistical information of the channel states and the harvested energy. Furthermore, only one Bisection search is required for the implementation of proposed scheme and hence its computational complexity is small. Simulation results are used to show the efficacy of the proposed scheme.
