Ericsson, China Unicom and Qualcomm successfully accomplished a large scale trial of three carrier aggregation in Chengdu, capital city of Sichuan Province.

The trial achieved a downlink peak rate of 375Mbps for single user, fully proving the large-scale field networking capabilities of carrier aggregation and further clarifying the roadmap for LTE network evolution.

In 2016, China Unicom Network Technology Research Institute launched the "China Unicom LTE Three-carrier Aggregation New Technology Test" Project. To support implementation of the project, Ericsson and China Unicom Chengdu Branch carried out trials of continuous three-carrier aggregation in the live network in Chengnan High-Tech Zone of Chengdu. As the first chip supplier to launch a three-carrier aggregation commercial processor, Qualcomm Technologies provided the User Equipment with the latest Qualcomm® SnapdragonTM820 processor with X12 LTE for this trial.

The trial targeted an area of 25 macro base stations for the testing, all of which became available for access on April 12. Upon the start of the field trial at dawn the next day, a downlink peak rate of 375Mbps was immediately reached for single user. Overall, the trial achieved an average rate of 373.7Mbps and specifically, an average 255Mbps downlink rate for single user during road test.

Meanwhile, based on the needs of the local market, Ericsson successfully accomplish three-carrier aggregation on the Ericsson Radio Dot System at China Unicom Sichuan Tianfu Information Center. This is the first three-carrier aggregation achieved with Ericsson Radio Dot System in China, which enriches technical experience, and provides a solution for the deployment of indoor three-carrier aggregation at major buildings of China Unicom.
