We investigate the power allocation among multiple beams in our previously reported non-orthogonal access with random beamforming and intra-beam successive interference canceller (SIC) for cellular multiple-input multiple-output (MIMO) downlink. By equally allocating transmission power among multiple beams, the average of user throughput within a cell can be enhanced due to the effective use of spatial multiplexing. Meanwhile, the throughput of users at the cell edge may be improved by non-equal transmission power allocation among beams since the inter-beam interference is decreased and received signal power is increased from the viewpoint of the main beam to which most of the transmission power is allocated. The tradeoff between the average and cell-edge user throughput by using the control of transmission power allocation among multiple beams which is frequency block dependent in addition to the inter-cell interference coordination by the fractional frequency reuse (FFR) which utilizes the different transmission power allocation among frequency blocks is quantitatively evaluated. |
