Title 6G Upper Mid-Band Device MIMO Communications: Extreme Receive Antennas-Aided MIMO and Modular MIMO antennas Abstract For future six-generation (6G) upper mid-band mobile communications, the higher-order device MIMO such as the 8 x 8 MIMO is envisioned for the smartphone to achieve increased data rates for the user. However, it is worth noting that the 8 x 8 MIMO requires two times the transmitted power of current 5G 4 x 4 MIMO and has a more complex system architecture. Thus, whether it is cost effective to apply the 8 x 8 MIMO for increased data rates is not clear. In this talk, based on the extreme receive antennas (ERA)-aided MIMO, we demonstrate that the 8 x 4 MIMO (8 receive antennas for 4 spatial streams) with the same transmitted power as the 5G 4 x 4 MIMO can outperform the 8 x 8 MIMO to achieve higher data rates and lower energy per bit as well. The MIMO performance is experimentally conducted in the 7.1 GHz band in the campus outdoor scenario by applying modular MIMO antennas as receive antennas in the smartphone covering 6.425-8.4 GHz in the upper mid-band, which is promising to be a prime 6G mobile spectrum. The 8 x 4 MIMO in the outdoor field test can obtain a spectral efficiency of 31 bps/Hz; that is, with only 200 MHz bandwidth, the data throughput for the user can be larger than 6 Gbps in the 7.1 GHz band. The ERA-aided MIMO system and the MIMO performance based on applying modular MIMO antennas will be addressed.
