Huawei and LG U+ announced they have completed a series of joint tests based on three 5G commercial scenarios: enhanced mobile broadband (eMBB), ultra-reliable low latency communications (uRLLC), and massive machine-type communications (mMTC). Results: cell peak rates of 31 Gbps and latency under 0.5 ms.
According to Huawei, 5G must enable eMBB services that require ultra-large broadband and uLLC and mMTC services for applications such as smart driving and Internet of Things (IoT) to satisfy diverse service requirements.
During the test procedures, Huawei and LG U+ verified key technologies of 5G New Radio. Simultaneously using a short transmission time interval and f-OFDM, latency was reduced to 0.5 ms. An adoption of Sparse Code Multiple Access (SCMA) allows for a significant increase in the number of cell connections for mMTC.
Since new immersive services such as virtual reality (VR) and augmented reality (AR) are steadily maturing, future wireless networks are required to provide gigabit transmission rates. Operators can obtain more continuous spectrum resources on millimeter waves than on low frequency bands, which provide large network capacity and excellent user experience in densely populated urban areas. In the joint testing phases, spectral efficiency demonstrated a noticeable improvement with cell peak rate reaching 31 Gbps supported on high-frequency bandwidth and Massive MIMO.
LG U+ and Huawei will perform further tests of LTE and 5G Dual Connectivity based on CloudRAN architecture, said Gan Bin, Vice President of Huawei Wireless Network. “In the near future, we will strengthen the cooperation and partnership with LG U+ and keep innovating to bring 5G into reality.”
Since signing a 5G MoU, Huawei and LG U+ have worked closely together to prepare for the pre-commercial use of 5G by 2018.
“We hope to provide the availability of 5G services for Korean users by 2018, and Huawei’s innovation insights and accumulated expertise will help us in achieving this goal,” said Kang Jung Ho, Vice President of LG U+.
