ZTE has completed Phase 1 of China’s high-frequency 5G field tests that include multi-user shared access (MUSA) tests as well as massive multiple input multiple output (MIMO) trials.

The company said the tests show that MUSA supports random escape in under 300 percent overload conditions in uplink grant-free transmission tests, making it applicable to high-capacity 5G Internet of Things (IoT) scenarios.

In addition, the new waveforms ZTE tested (also known as FB-orthogonal frequency division multiplexing) used scattered narrowband resources, making it appealing for services that require lower time domain and frequency domain synchronization.

ZTE says it is one of the first vendors to complete high-frequency tests in both indoor and outdoor line of sight (LOS) and non-LOS scenarios. In addition, ZTE’s prototype supports automatic beam capture and beam tracking as well as adaptive beam switching depending on channel quality.

ZTE is part of China’s 5G testing project that is planned by the government and led by the Ministry of Industry and Information Technology (MIIT) and implemented by China’s IMT-2020 5G group.

ZTE said the testing was part of Phase 1 of the 5G program, which includes technology R&D tests, and it will continue until 2018. These tests include technology verification, technical solution verification, and system verification.

The product R&D tests will take place from 2018 until 2020. The goal of China’s 5G testing project is to launch 5G commercially by 2020.
