Abstract(in English) In massive multiple-input multiple-output (MIMO) downlink, the transmitter beamforming (BF) to achieve the beamforming (power) gain and/or reduction in inter-user interference in multiuser MIMO case based on the channel state information (CSI)-feedback from the user terminals is essential. Massive MIMO requires large number of transmitter power amplifiers dedicated to each of transmitter antennas and allowable transmission power per power amplifiers (thus per transmitter antenna) is to be severely limited. Therefore, it is necessary to perform transmission BF in consideration of the limitation on the transmission power per antenna. In this paper, we consider the BF control using the firefly algorithm (FA) when there is a per-antenna transmission power constraint. FA is a kind of swarm intelligence and by mimicking the behavior of fireflies which moves toward neighbor fireflies based on distance and brightness of the neighbor fireflies, the solution to the multimodal optimization is obtained efficiently. By setting the BF matrix as a position of the firefly and the obtainable metric for the system throughput maximization as a brightness of the firefly, we apply the FA to the BF control. We evaluate the performance of BF control using FA from the viewpoint of the geometric mean user throughput by using computer simulations.
