This project aims to develop coordinated multi-point technologies for 5G NR networks with center and edge intelligence, covering from PHY layer to resource management, with an objective to develop a platform of advanced technologies for industrial applications. Besides the technologies, a system level simulator/emulator of 5G NR networks is also to be developed, capable of assisting researchers in R&D, verification and network deployment. Such a new model can effectively help elevate potential of domestic academia-industry community in 5G NR technology and product development, as well as service deployment.

 

Taking industrial benefits as a major emphasis, this project actively cooperates with partners from industry and research institutes, integrating research groups of NCTU and partners to develop key technologies for 5G NR mmWave network and an associated verification platform. The project consists of four sub-projects:

 

  • Sub-project 1 focuses on technologies for deployment planning and optimization for ultra dense mall cell networks (UDN) and self-organization network (SON)
  • Sub-project 2 focuses on technologies for interference management and resource management in cloud radio access networks (CloudRAN).
  • Sub-project 3 focuses on technologies for beam tracking and coordinated multi-point (CoMP).
  • Sub-project 4 focuses on technologies for hybrid beamforming and multi-user detection.

 

The Main project is responsible for coordinating and planning on R&D works of the sub-projects as well as developing a system level simulator/emulator for 5G NR networks, integrating the sub-project developed technologies into a high-efficiency computer-aided design and deployment (CADD) tool to facilitate industrial promotion. The outcomes of this project can be leveraged to assist Taiwan’s 5G industry in elevating its competitiveness on technology development and service deployment.

Millimeter wave Large Tile-based Phased Antenna Array and RFIC

 

Introduction to techniques

  1. The proposed novel wideband ultra-thin magneto-electric dipole antenna has a leading advantage in thickness;
  2. The proposed novel mmWave 3D double-curved air cavity patch antenna has a leading advantage in bandwidth;
  3. A multi-function mmWave RFIC integration technology has been developed and reduces the cost of mmWave RFIC automatic test equipment (ATE) solutions;
  4. A novel frequency reconfigurable switched-type phase shifter maintains low amplitude and low phase variations, which has a leading advantage in operation bandwidth.

 

Applicability of techniques to industry

  1. A multi-function mmWave RFIC integration technology has been developed and reduces the cost of mmWave RFIC automatic test equipment solutions. This joint project has been funded with 4,400,000 NTD by the MOST;
  2. This project has successfully developed a wideband tile-based phased array antenna. We currently work with ITRI to jointly develop a solution of satellite payload antenna array with a funding size of 800,000 NTD.
  3. A novel mmWave 3D double-curved air cavity patch antenna has been realized through an industry-academic joint project with PCB manufacturer.
