A Layer 1-Layer 2 (L1 / L2) Triggered Mobility (LTM) handover (HO) procedure, and method. A gNB-Centralized Unit User Plane (gNB-CU-CP) sends Radio Resource Control (RRC) messages with LTM candidate cell configuration of LTM candidate gNB-DUs. Based on the RRC messages, a Layer (L1) Measurement Report is sent to the LTM candidate gNB-DUs. In response, the LTM candidate gNB-DUs determine whether a radio condition of the LTM candidate gNB-DUs meet a predetermined resource reservation criteria. Based on meeting the predetermined resource reservation criteria, the LTM candidate gNB-DUs initiate reservation of radio resources for an LTM candidate cell for a LTM cell switch. The LTM candidate gNB-DUs send to the gNB-CU-CP an updated LTM candidate cell configuration. The gNB-CU-CP sends the updated radio resource configuration to the UE via the serving gNB-DU.
