About the project
Objective
This project aims to explore the emerging gigantic multiple-input multiple-output (gMIMO) technology in the physical layer, using methodology from signal processing and information/communication theory. gMIMO relies on using 10 times more antennas in base stations and user devices than in current networks, by operating in the upper mid-band where antennas are smaller. This enables massive spatial multiplexing and beamforming. The research results are anticipated to be applied to 6G and future wireless communication networks and provide valuable insights into their integration within a wide range of digital transformation.
Background
Sixth-generation (6G) wireless communication is crucial for enabling society’s digital transformation and future cyber-physical world. Many transformative applications, such as ultra-massive connectivity, immersive extended reality (XR) communication, smart factories, and intelligent transportation systems, can be efficiently facilitated by intelligent 6G wireless networks. To support these extensive usage scenarios, delivering exceptionally high data rates to many users is important. Since fourth-generation (4G) wireless networks, multiple-input multiple-output (MIMO) technology has been a key technology to deliver higher rates.
With the advancement of wireless networks, MIMO technology has also significantly evolved with the continually increasing number of antennas. To further empower the 6G and future wireless networks, gigantic MIMO (gMIMO) is highly anticipated by utilizing hundreds or a thousand antennas, which is the major focus of this project.
