Huawei Assists China Mobile Verification of Key TD-LTE-Advanced Technologies in Field Tests
Huawei, a leading global information and communications technology (ICT) solutions provider, together with China Mobile, verified multiple core TD-LTE-Advanced technologies including FDD/TDD Carrier Aggregation, MSA, 256QAM, inter-site CoMP, and MU-MIMO in a field test conducted at Chengdu Electronic Technology University. The verification marks a milestone in improving the entire TD-LTE network performance and user peak throughput.
Jointly established by China Mobile, Huawei, and Chengdu Electronic Technology University, this field test is a very important platform for the validation, evolution, and innovation of new TD-LTE Advanced technologies. As pre-commercial verification for the 3GPP R12 standardization process, it will accelerate the development of the TD-LTE-Advanced industry and speed up scale for commercial use of these technologies.
LTE TDD & FDD Carrier Aggregation (CA) is one of the most important technologies in 3GPP R12 standards. This test has enabled China Mobile and Huawei to validate the CA peak throughput by considering a scenario where LTE TDD is the primary cell and LTE FDD is the secondary cell. The air interface test results reached the theoretical peak data rate corresponding to a used network configuration of 250Mbps.
Another key technology of 3GPP R12 standards is LTE Multi-Stream Aggregation (MSA). MSA between TD-LTE and LTE FDD sites were both tested, with the results showing flexible handover or traffic concurrency for users, based on network coverage, load and interference.
As part of the field test, China Mobile and Huawei validated MU-MIMO with four data streams based on an 8-antenna network, which resulted in a peak data rate improvement of 100%. The test result for inter-site CoMP on a PTN-based network also showed a 30% increase in throughput for cell edge users.
In addition, Huawei accomplished a TD-LTE indoor and outdoor test with 256QAM to become the world's first vendor to successfully conduct a high-order modulation test. Compared to 64QAM, 256QAM enables a 33% peak data rate gain, and a cell average performance improvement of more than 20% in an indoor test environment.
