Query: 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 averaged 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 quality
of service constraint on its required instantaneous rate. 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 schemes do not require any statistical information of the channel
states and the harvested energy. The proposed power allocation schemes entail
in small complexity based power allocation decisions. Therefore, the proposed
schemes can provide solutions in real time and are more suited for online power
allocation problems where the system state parameters (e.g. channel state,
harvested energy etc) change quickly. The performances of the proposed schemes
are demonstrated with the help of simulation results.
