| Abstract | (in Japanese) | (See Japanese page) |
| (in English) | The 5th generation mobile communication system (5G) will introduce the use of higher frequency band with wider bandwidth and Massive MIMO technology for realizing super high bit rate and higher system capacity of more than 10 Gbps. In high-SHF band Massive MIMO, from the point of view of realization, as a novel method for hybrid beamforming (BF) that combines analog BF with digital precoding, joint processing of fixed analog BF and channel state information (CSI)-based precoding (FBCP) has been proposed. Moreover, transmission performance in multiuser conditions mainly depends on inter-user interference, and thus a low-complexity user selection algorithm that selects users from multiple users on maximum throughput criterion has been also proposed for FBCP. On the other hand, it is important to evaluate the proposed algorithms in the real radio channel, because the Massive MIMO performance highly depends on propagation channel characteristics. In this report, we measure propagation channels by using horn antennas that simulate the fixed analog BF in 28 GHz band indoor propagation experiments, and verify the effectiveness of the proposed user selection algorithm by computer simulations using real propagation channel data. | |
