- Abstract
- This paper proposes a multi-radio multi-connectivity (MR-MC) technology to meet the 6G service requirements. To overcome the challenges of high path loss and directionality in the sub-THz band, we designed an MR-MC architecture that simultaneously connects to LTE, NR, and sub-terahertz (THz) bands. CHO and CPC/CPA were used to support reliable mobility enhancement. Simulation results demonstrate that the proposed structure effectively reduces signal delay and service outage issues through multi-connectivity. Furthermore, by utilizing pre-configured interfaces, the approach significantly decreases signaling overhead, thereby enhancing real-time performance.
