Huawei has recently completed the Massive MIMO verification test using the operator's 40 MHz spectrum on the 3.5GHz band in Tokyo, Japan. The pair adopted Massive MIMO and multi-carrier technologies with the peak downlink rate reaching 1.4 Gbps. The test represents another collaboration regarding Massive MIMO between the two companies since September 2016 when SoftBank announced the "5G Project" programme using 2.5GHz band on the TDD (AXGP) commercial network operated by Wireless City Planning Inc. and is also the world's first Massive MIMO trial on the 3.5GHz band.
The 3.5GHz band, with its abundant bandwidth resources, has already gained a reputation as one of the most popular bands throughout the world. This offers a great opportunity for the global development of LTE TDD, and has grown increasingly important as a 5G catalyst to assume the spotlight position of the global mobile industry. Massive MIMO, featuring the incorporation of massive antennas and 3D beamforming, enhances spectrum multiplexing among multiple UEs to significantly improve spectral efficiency without additionally increasing site density or bandwidth. The 3.5GHz Massive MIMO test further explores the latent potential of 3.5GHz spectrum, and is expected to open up a new commercial era of LTE-Advanced.
SoftBank has experienced several years of exponential growth, showing a remarkable increase in traffic. Traffic has risen by a factor of 2,300 times within the last ten years, and this continued growth trend is expected to remain stable over the next three to five years. In response to the rapid growth in traffic, SoftBank, with the assistance of Huawei, has deployed a large number of commercial Massive MIMO sites at key locations in Tokyo, Osaka, and Nagoya since September 2016. In February 2017, Huawei secured the lead in completing massive MIMO+multi-carrier verifications on the 3.5GHz band, consolidating SoftBank's technological advantages in network deployment using 3.5GHz spectrum.
Together with SoftBank, Huawei seeks to further entrench industrial cooperation and joint innovation regarding LTE evolution to develop the most advanced mobile communications technologies.
