Method and apparatus for preparing ltm in a wireless communication system

A target radio access network (RAN) node comprising:

• at least one transceiver;
• at least one processor communicatively coupled to the at least one transceiver;
• at least one memory, communicatively coupled to the at least one processor, storing instructions executable by the at least one processor individually or in any combination to cause the target RAN node to:
• receive, from a source RAN node over an Xn interface, a handover request message including an L1/L2 layers triggered mobility (LTM) information request information element (IE), and
• transmit, to the source RAN node over the Xn interface, a handover request acknowledge message as a response to the handover request message, the handover request acknowledge message including an LTM information response IE.
