A Method of Access Node Change in Multi-Radio Multi-Connectivity.

3GPP introduces multi-radio dual-connectivity technology using FR1 and FR2. It is a method of using enhanced Mobile Broad Band (eMBB) in the high-frequency band while supporting the reliability of the connection. 6G tries to provide Tbps-level datarate by using sub-terahertz (0.1~0.3 terahertz) or higher bands, but it needs to solve the issues such as the extremely sensitive NLOS path loss characteristics. For this purpose, extremely fine beamforming technology based on a large-scale antenna array is required, and in this paper, we will introduce a method of reducing path loss rate and supporting end-to-end low latency using multi-radio multi-connectivity (MR-MC) technology.
