Mediatek Collaboration Itri Scraping 5g Commercial

MediaTek has been aggressively pursuing the 5G market. Together with ITRI, it has developed LWA (LTE / Wi-Fi Link Aggregation) technology to improve network transmission bandwidth and 38/39 GHz millimeter-wave high-band access technology , And MUST (Multi-User Superposition Transmission) technology that supports the transmission capacity of small base stations. It has made headway and business opportunities for Taiwan to enter the global 5G communications market and is moving towards the goal of 5G network commercialization by 2020.

ITRI and MediaTek With the support of the Science and Technology Project of the Ministry of Economic Affairs and Technology, both parties have started the 5G technology research and development cooperation from 2015, and have made important breakthroughs in the most basic technology research and development, 5G test field and key standard patent layout.

Institute of IT Research Institute Que Chi grams, said ITRI and MediaTek have very close cooperation at the 2016 World Conference on Mobile Communications (MWC), the two sides have already demonstrated the world's first LWA system, the world's leading Networking speed to 700 Mbps, in order to link the domestic manufacturers to form a state-owned industrial chain of ecology, paving the way for 5G technology research and development in advance.

Zhou Yujun, head of MediaTek Technologies, said that it has established a good foundation for cooperation with LWR in the research and development of LWA and 38/39 GHz high-frequency millimeter-wave access technologies and has devoted more efforts to the development of 5G MUST systems this year. MediaTek is the first company in the world to apply multiuser interference cancellation technology to handset receivers. Using ITRI's MST technology-enabled test environment, MediaTek has completed the verification of this technology in a wireless environment for In 5G system business laid a solid foundation.

In order to solve the 5G high-frequency transmission problem, ITRI and MediaTek jointly focus on the internationally recognized frequency band of 38 / 39GHz, which is put into research and development earlier. In addition, the advanced layout of Beam-forming, Beam-tracking, , Phase-locked loop and other technologies, the peak transmission rate of up to 1Gbps, supporting more than 100Km / hr mobile transmission and coverage of 100 ~ 200 meters, the two sides demonstrated the world's first set of LTE early this year combined with 38 / 39GHz millimeter-wave 5G BTS Type system, 5G R & D reserve kinetic energy, into the international advanced group.

In the crucial moment before the 5G standard was established in 2018, both parties jointly invested in the research and development of 5G MUST technology to realize such functions as non-orthogonal multiple access (NOMA), multi-user interference cancellation (MUIC) and new air interface. With ITRI The provided MUST scheduling technology and field measurement environment have successfully completed the functional testing and performance measurement with MediaTek's handsets. Compared with the 4G measurement, the 4G spectrum achieves an average network spectrum efficiency of 10% to 40%. In addition, Up to 140% in certain environments.
