| Abstract(in English) | This paper propose a new control scheme that the base station (BS) controls terminal's transmit beamforming in multi-input multi-output (MIMO) channel. In the proposed scheme, the BS transmits pilot signals using proper downlink beamforming to instruct the target beamforming to the terminal. Using responses of the pilot signals from the BS, the terminal computes weight for transmit beamforming. We present theoretical principle of the control scheme and terminal's actual weight computation in the presence of noise. The proposed scheme controls not only a single transmit beamforming but also multiple transmit beamforming simultaneously. Numerical results show that the terminal can yield accurate transmit weight close to the target weight in the presence of noise. |
