Huawei announced that it has completed the first phase of key 5G technology tests as part of a series of field trials defined by the IMT-2020 5G Promotion Group. Recently. the Chinese telecoms vendor conducted an outdoor 5G macro-cell tests in Chendu, China which involved the deployment of key enabling technologies, namely the 5G air-interface.
Huawei said that the test results successfully demonstrated that the new 5G air interface technology can effectively improve spectrum efficiency and meet diverse service requirements for 5G as defined by the ITU-R. The technology has been implemented through three novel foundational technologies i.e. filtered Orthogonal Frequency Division Multiplexing (F-OFDM), Sparse Code Multiple Access (SCMA) and Polar code.
In the test, the multi-user MIMO (MU-MIMO) method which was used 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, almost 10 times of that in the LTE baseline system. Full Duplex mode has also been tested which 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.
Huawei also announced plans for the second phase of the 5G test which will focus mainly on coverage, hotspot capacity and massive connections with high reliability and low latency with reduced power consumption.
Dr. Wen Tong, Huawei 5G Chief Scientist
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 complete 5G key technologies tests and corresponding system integration test based on our proposed 5G new air interface.
