Chinese vendors Huawei Technologies and ZTE have announced the completion of their respective tests in the second phase of China’s 5G technology tests, with Huawei focused on 5G New Radio and ZTE on massive machine type communication (mMTC).

Huawei said it completed its test in Beijing ahead of schedule using 5G New Radio, massive MIMO, and other technologies using 200 MHz of bandwidth to achieve single-user downlink throughput of over 6 Gbps and cell peak rate of over 18 Gbps.

Huawei says its 5G test terminal enabled more than 100 channels of 4K UHD video on a single 5G base station. Huawei also claimed to be the first vendor to complete a 5G network slicing test.

During the test procedures, Huawei implemented interoperability tests involving radio frequency and interworking functions together with upstream and downstream vendors. Huawei partnered with instrument vendors (Rohde & Schwarz, Keysight Technologies, and DT Link Tester), chipset vendors (Spreadtrum Communications and MediaTek), and other companies.

Meanwhile, ZTE announced it has become the first vendor to complete the mMTC field test in the second phase of China’s 5G test.

The test result showed that the number of connected terminals was increased by nearly 600%, reaching an equivalent density of 10 million connections.

ZTE used its multi-user shared access (MUSA) technology to enhance the number of connections. By introducing short extended codes into the field, said ZTE, MUSA allows high overload, eliminates scheduling operations and simplifies synchronization and power control, increasing the number of connections by three to six times.

In the coming 5G era, said ZTE, the IoT will become the main driving force for 5G development, and mMTC is one of the three major application scenarios identified by the ITU-R, which specifies as one of its KPIs for 5G networks a density of 1 million connections per square kilometer. To do that, 5G must resolve challenges such as enormous scheduling resources and power consumption.
