n the code structure to transmit usefulinformation of user and at the same time it supports channel coding of any code ratewith an appropriate code construction to fit any future service requirements. The test results showed that Polar code provided coding gain from 0.5dB to 2.0dBcompared with Turbo code used in LTE system.

System Integration of Innovative 5G Air Interface Technologies: -

The flexible system integration of several innovative 5G air-interface technologies, namely, F-OFDM, SCMA and massive MIMO has been verified in the first phase of key 5G technology tests.

In the test, multi-user MIMO (MU-MIMO) supported up to 24 users and up to 24 parallel layers transmission on the same time-frequency resources. The test results showed that MU-MIMO can achieve 3.6Gbps cell average throughput using 100MHz system bandwidth, it is almost 10 times of that in LTE baseline system.

The trial has validated the optimal integration of the above new radio technologies and the capability of flexible 5G air-interface technologies, the trial is also served as a technical re-risk to support  the on-going 3GPP standardization work.

Full Duplex Implemented in the First Phase of 5G Test: -

Full Duplex mode has also been testedin the first phase of 5G test. In the initial test stage on Full Duplex, it allows simultaneous transmitting and receiving of data at the base station with three level cascaded technologies, namely, passive analog cancellation, active analog cancellation, and digital cancellation. The test results showed that the Full Duplex can provide self-interference cancellation capabilitymore than113dB in real world environmentand result in a total 90% system throughput gain over the conventional half duplex mode used today.

Huawei has successfully completed the first phase test of 5G technologies in China. "The trial of 5G technologies in Chinawill be a great contribution to 5G applications in the future.” Dr. Wen Tong, Huawei 5G Chief Scientist emphasized that, "As a member of the IMT-2020 5G Promotion Group, Huawei is pleased to work with CAICT, China Mobile, China Unicom, and China Telecom, and took the initiative to be the first to complete5G key technologies tests and correspondingsystem integration testbased on our proposed 5G new air interface."

He also announced the plan of the second phase of 5G test which will focus mainly on the wide coverage, high hotspot capacity, and massive connections with high reliability, low latency with reduced power consumption.
