Reconfigurable Intelligent Surface (RIS) and Factors Influencing Its Role in Future Networks
One of the key efforts in the 5G era is to tap into vast chunks of the spectrum at high-frequency bands and make them suitable for wireless mobile communication.
RAN-CN Convergence Towards the Next-Generation Networks
6G system is expected to be a platform providing hyper-connectivity to everyone and everything in the 2030’s. Along with continuous improvement of 5G services, new 6G services with various requirements are emerging, such as truly immersive extended reality, high-fidelity mobile hologram, collaborative robots, and digital replica.
Towards 6G AI: AI-based Non-linearity Compensator
Coverage is one of the most important metrics in wireless communication systems. In general, since the transmission power of user equipment (UE), e.g., smartphone, is much smaller than that of base station, uplink communication coverage is shorter than downlink communication coverage.
