Reconfigurable Intelligent Surface (RIS) Applications in FR3 and NTN
High bandwidth, low latency, and wide coverage are the three primary objectives of 5G. In the B5G/6G era, in addition to upgrading these three goals, concepts of low-power environmental sustainability and AI applications are incorporated. Therefore, this project will explore the application of Reconfigurable Intelligent Surfaces (RIS) to enhance electromagnetic wave efficiency, focusing on two B5G technologies:
FR3 frequency band and Non-Terrestrial Networks (NTN). The research topic content is summarized as follows:
a. B5G/6G FR3 (7~24 GHz):
o The FR3 frequency band lies between 5G FR1 and FR2.
o FR1 and FR2 technologies respectively focus on the design of overall channel capacity (MIMO) and main beam Line-of-Sight (LoS) signal strength (Phase Array).
o This project will analyze how RIS, which can alter the electromagnetic wave propagation path in space, can enhance the channel capacity and signal strength of FR3.
b. NTN Low Earth Orbit (LEO) Satellites:
o The communication distance between LEO satellites and the ground is greater than 350 kilometers, resulting in significant electromagnetic wave path loss.
o Phased arrays are typically used to increase the required signal-to-noise ratio for communication, achieving electronic beam steering.
o However, challenges include power consumption, heat dissipation, and BFIC cost.
o This project will utilize RIS to achieve Electronic Beam Steering (ESA) with low power consumption.
All of the above projects will incorporate Over-The-Air (OTA) measurement technology to verify the theoretical analysis results.
