Abstract:
This talk addresses future six-generation (6G) upper mid-band mobile communications based on applying the extreme receive antennas (ERA) in the form of modular MIMO antennas embedded in the mobile device or smartphone. The ERA-aided MIMO communication is especially promising for applications in the lower frequency portion of the upper mid-band such as 7.125-8.4 GHz and the upper 6 GHz (6.425-7.125 GHz) for achieving stable high speeds for the users. By applying the modular MIMO antennas, we can conveniently embed many MIMO antennas in the mobile device to be at least twice the spatial streams in the MIMO communication. In this case, with the same transmit power at the base station like the current 5G 4 x 4 MIMO, the mobile device with 8 or 12 MIMO antennas can support a higher signal modulation to achieve a spectral efficiency up to 32 or 37 bps/Hz, at least about twice that of the 5G 4 x 4 MIMO. This is because the extra MIMO antennas in the mobile device can function like virtual power amplifiers to increase the received signal noise ratio (SNR) and furthermore like virtual external elements such as RIS elements added in the environment to increase the multipath signals toward the device. Additionally, it can lead to simple 6G system complexity, 5G/6G base station co-location, and high energy efficiency for increased user-experienced data rates, which meet the 6G industry priorities. Moreover, the 8 x 4 MIMO can also outperform the 8 x 8 MIMO communications to have a larger spectral efficiency for the user. The principle of the ERA-aided MIMO communication with the modular MIMO antennas will be introduced. The 4 x 4, 8 x 4, and 8 x 8 MIMO performance field test conducted in the NSYSU campus outdoor scenario will also be presented and analyzed.
