Large-scale antennas take full advantage of the vertical and horizontal dimensional freedom in 3D channels and have great advantages in terms of spectrum utilization efficiency and system capacity, and are therefore recognized as the key technologies in 5G eMBB scenarios.
In April 2016, Datang released the world's largest 256 large-scale antenna. The product uses high-end space multiplexing pilot transmission, channel status feedback and other programs to support the maximum 32-stream transmission; in the sending and receiving programs, multi-user pairing and scheduling mechanisms, put forward in the high efficiency and low complexity of innovation In addition, this product introduces a new design scheme in array structure design, integrated transceiver, high efficiency amplifier, antenna calibration, heat dissipation, etc. . Measured in the 3.5G band, the use of 100MHz bandwidth, 20 simultaneous data streams, the rate of 4Gbps, the industry leader.
In September of this year, Datang has completed all the tests of the first phase of the 5G technology test, including technical verification of large-scale antennas, non-orthogonal multiple access, and ultra-dense networking. For the large-scale antenna, the average performance of the system and the extreme performance of the user-distributed system are also tested on the basis of the peak rate, which fully verifies the use effect of the large-scale antenna in various environments.
