Huawei has announced it has completed the first stage of key 5G technology tests as part of a series of 5G field trials organized by the IMT-2020 5G Promotion Group.

The vendor completed outdoor macro-cell tests in Chengdu, China consisting of a number of key 5G enabling technologies and an integrated 5G air interface.

As part of the trial, Huawei evaluated three foundational technologies - filtered orthogonal frequency division multiplexing (F-OFDM), sparse code multiple access (SCMA) and polar code - the air interface technology.

Results show that F-OFDM was able to improve system throughput by 10%, SCMA was able to increase uplink connections by 300% and downlink system throughput by up to 80%, and polar code provided coding gain of between 0.5dB and 2dB compared to the code used in LTE systems.

Huawei said results of the test demonstrate that the new 5G air interface technology can improve spectral efficiency and meet the ITU-R's diverse service requirements for the standard.

The IMT-2020 5G Promotion Group was launched by the China Academy of Information and Communication Technology to encourage joint efforts to promote 5G field trials and evaluations among the global mobile industry.

Earlier this year the group announced a three-phase 5G trial plan spanning from 2016 to 2018.
