A Novel Beamforming Scheme for Mobile-to-Mobile Millimeter Wave Communications

Due to using beamforming technology in millimeter wave (mmWave) communication, the movement of transmitter (Tx) and receiver (Rx) will cause the mis-alignment of Tx and Rx beams. In order to deal with this problem, a novel physical layer beamforming scheme is proposed in this paper, namely, double Gaussian beams (DGBs) scheme, which treats the static and moving Tx/Rx scenarios in the same manner. We model the DGBs channels by three Markov states, and the connection ratio of Markov state is used as the metric to study the performance of DGBs scheme from the channel point of view. We show that the DGBs channels have very similar light-of-sight (LOS) state connection ratio compared with that of the measured mmWave channels based on similar set up of the Tx and Rx beams.
