Institute of IT Research Institute Que Chi grams, said ITRI and MediaTek have very close cooperation at the 2016 World Mobile Congress (MWC), the two sides have joined hands to demonstrate the world's first LWA system, the world's leading network Speed up to 700 Mbps, in order to link the domestic manufacturers to form a state-owned industrial chain ecological, paving the way for 5G technology development in advance; the same year, also jointly developed specifications to jointly develop the world's first 38 / 39GHz millimeter-wave high frequency access embryonic system , Outdoor support for mobile transmission at over 100 Km / hr and Gbps levels, joint development and deployment of key technologies such as phase array antennas and beam tracking 2017 Jointly Launched in 2017 to Launch the World's First LTE Combined 4G / 5G dual-mode small base station prototype system, breaking the bottleneck of access to high-band technology to demonstrate its own 5G R & D capabilities.
MediaTek senior vice president and technology chief Zhou Yuejun said that ITRI is MediaTek in capital and communications technology research and development of an important partner in LWA and 38/39 GHz millimeter-wave high-frequency access technology research and development process, the establishment of good cooperation Tacit understanding basis, this year more into the 5G MUST system development MediaTek is the world's first multi-user interference cancellation technology used in mobile receiver company, using ITRI to provide support for MUST technology test environment, MediaTek to complete this technology Verification in a wireless environment has laid a solid foundation for its commercial use in 5G systems.
ITRI pointed out that in the post-4G era, ITRI and MediaTek in order to solve the problem of soaring demand for broadband transmission, without increasing the operator's operation and construction costs, the research and development of LWA technology will enable mobile handsets The device can simultaneously transmit data using LTE and Wi-Fi to enhance the bandwidth and efficiency of network transmission and facilitate the early completion of interoperability testing with CLP China to provide the world's 'LWA 4G + Wi-Fi Botswana service' The first provider of commercial LWA system operators.
In order to solve the 5G high-frequency transmission problem, ITRI and MediaTek also jointly focus on the internationally recognized frequency band of 38 / 39GHz, which is put into research and development earlier. In addition, Beam-forming, Beam-tracking, Antenna array, phase-locked loop and other technologies, the peak transmission rate up to 1Gbps, to support more than 100Km / hr mobile transmission and coverage of 100 ~ 200 meters, the two sides demonstrated earlier this year the world's first set of LTE combined with 38 / 39GHz millimeter-wave 5G small Base station prototype system, 5G R & D reserve kinetic energy, into the international advanced group.
ITRI said that at the crucial moment before the 5G standard was established in 2018, the two companies 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. By means of the MUST scheduling technology and field measurement environment provided by ITRI, the functional tests and performance tests of MediaTek mobile terminals have been completed successfully. In comparison with the actual test, 4G network spectrum with an average increase of 10 to 40% can be obtained Efficiency, and up to nearly 140% in certain environments.
ITRI pointed out that it will continue its close cooperation with MediaTek in the field of 5G R & D and energy complementarity, will play the role of a chip platform and technology provider, and will build Taiwan's 5G eco-link with Taiwan's high-tech and telecom industries for Taiwan Enter the global 5G communications market to obtain opportunities and business opportunities, towards the goal of 5G network commercialization in 2020.
