TOKYO -- Huawei announced today the world’s first successful large-scale field trial of 5G new radio access technologies. The field trial was conducted jointly with NTT DOCOMO, Inc., Japan’s largest mobile service provider. Experts from both companies participated the field trial in an outdoor test site in Chengdu, China. As an on-going field trial, Huawei was able to stream live video of trial activity to its booth at the CEATEC JAPAN 2015 trade show at Makuhari Messe in Chiba.
Today’s trial represents the first large-scale Multi-User MIMO (MU-MIMO) technology test, with a concurrent connectivity of 24 user devices in the macro-cell environment on the sub-6GHz frequency band. It is also the first time to validate the performance of Sparse Code Multiple Access (SCMA) and Filtered OFDM (F-OFDM) in the field, both of which are 5G new air interface technologies proposed by Huawei. The cell average downlink throughput of MU-MIMOs is 1.34Gbps, with 3.6Gbps on download peak throughput in a 100MHz ultra-wide band channel; these speeds are more than 10 times faster than single layer Single User MIMO (SU-MIMO) technology. The joint trial of 5G new radio access technologies is a key step toward accelerating 5G standardization and commercialization.
