| Abstract | (in Japanese) | (See Japanese page) |
| (in English) | The 5th generation (5G) radio access network will introduce the use of higher frequency bands with wider bandwidth and Massive MIMO technology for realizing super high bit rate and higher system capacity of more than 10 Gbps. In Massive MIMO using higher frequency bands, 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. On the other hand, the user selection algorithm is an essential technique for multi-user MIMO because the transmission performance of multi-user MIMO suffers from inter-user interference. However, in multi-user Massive MIMO, the computational complexity for user selection must be reduced. In this report, we propose a 2-step user selection algorithm with analog fixed BF beam based user selection for high SHF wideband Massive MIMO using FBCP in multi-user environment. The throughput performance of multi-user Massive MIMO using the proposed algorithm is evaluated by computer simulation. | |
