Transmit Beam Selection Scheme for Massive MIMO using Expected Beam Responses
Yoshihito Kubo, Yukitoshi Sanada (Keio Univ.) RCS2018-55
Abstract (in Japanese) (See Japanese page) 
(in English) Massive multiple-input multiple-output (MIMO) realizes simultaneous transmission to a large number of mobile stations (MSs) and improves frequency utilization efficiency. It is drawing attention as one of the key technologies of the fifth-generation (5G) mobile communication systems. The 5G system is going to be implemented in a high frequency band and beamforming (BF) with the massive MIMO is applied to compensate propagation loss. In a conventional BF scheme, a transmit beam is selected based on the power of received signals over subcarriers. The signal on a different subcarrier is transmitted with a different directivity. To improve the accuracy of beam selection, this paper proposes a transmit beam selection scheme for the massive MIMO. The proposed scheme calculates the expected responses of the signals over the subcarriers based on the relative directivity between a base station (BS) and a MS. The MS calculates correlation between the received signals and each of the expected response sequences. It then selects the beam with the highest correlation value. It is shown in this report that the proposed scheme can improve the average signal-to-noise ratio of a received signal by about 1.5dB as compared with that of the power based search scheme. It is also shown that the proposed scheme with limited response coefficients can reduce computational complexity by a factor of $1/100$ while it still increases the average SNR by about 1.0dB.
