Abstract
In general, the current subject matter relates to layer 1/layer 2 (L1/L2) triggered mobility (LTM) for intra-base station centralized unit user plane (CU-UP) relocation. In some implementations, a target distributed unit (DU) of a base station to serve a user equipment (UE) can be determined to be served by a target CU-UP of the base station. A serving CU-UP of the base station can serve a serving DU of the base station that is currently serving the UE. Using a centralized unit control plane (CU-CP) of the base station, the target CU-UP can be prepared for layer 1/layer 2 triggered mobility (LTM), and, using the CU-CP, the target DU can be prepared for LTM.
