Title:

METHOD AND APPARATUS FOR SUPPORTING L1/L2-BASED MOBILITY IN CU-DU SPLIT IN A WIRELESS NETWORK SYSTEM

Document Type and Number:

WIPO Patent Application WO/2024/071539

Kind Code:

A1

Abstract:

A method and apparatus for supporting L1/L2-based mobility in CU-DU split in a wireless network system is provided. A DU of a gNB receives, from a UE, a Layer 1 (L1) measurement report. A DU of a gNB transmits, to a CU of the gNB, a UE Context Modification Required message including information on at least one candidate target cell. A DU of a gNB receives, from the CU of the gNB, a UE Context Modification Confirm message include information on a target cell among the at least one candidate target cell. A DU of a gNB transmits, to the UE, a cell switching command including information on the target cell.
