Instantaneous and statistical resource allocation for wireless powered one-way relaying with multiple antennas

We consider a wireless-powered multi-pair relaying network with a multi-antenna relay which applies the energy beamforming (BF) for wireless powering and zero-forcing BF for the information relaying. For the network, power and time allocation problems are tackled to maximize the minimum achievable r...

Summary:We consider a wireless-powered multi-pair relaying network with a multi-antenna relay which applies the energy beamforming (BF) for wireless powering and zero-forcing BF for the information relaying. For the network, power and time allocation problems are tackled to maximize the minimum achievable rate among the device pairs with the instantaneous channel station information (CSI) and statistical CSI, respectively. The results show that the optimized performance with the statistical CSI deviates from that with the instantaneous CSI with a not-solarge number of antennas but the deviation becomes negligible with a large number of antennas.
