Online Power Allocation at Energy Harvesting Transmitter for Multiple Receivers With and Without Individual Rate Constraints for OMA and NOMA Transmissions

In this paper, we propose an online power allocation scheme to maximize the time average of the expected value of sum rate for multiple downlink receivers with energy harvesting transmitter. The transmitter employs non-orthogonal multiple access (NOMA) and/or orthogonal multiple access (OMA) to transmit data to multiple users. Additionally, we consider the scenario where each individual user has a...
