name: LTM
full_form: L1/L2 Triggered Mobility
context: Cell switch command is conveyed in a MAC CE, which contains the necessary information to perform the LTM cell switch. The overall procedure for LTM is shown in Figure 9.2.3.5.2-1 below. Subsequent LTM is done by repeating the early synchronization, LTM cell switch execution, and LTM cell switch completion steps without releasing other LTM candidate configurations after each LTM cell switch completion. The general procedure over the air interface is applicable to SCG LTM. Further details of SCG LTM can be found in TS 37.340 [21]. Figure 9.2.3.5.2-1. Signalling procedure for LTM The procedure for LTM is as follows: 1. The UE sends a MeasurementReport message to the gNB. The gNB decides to configure LTM and initiates LTM preparation. 2. The gNB transmits an RRCReconfiguration message to the UE including the LTM candidate configurations. 3. The UE stores the LTM candidate configurations and transmits an RRCReconfigurationComplete message to the gNB. 4a. The UE performs DL synchronization
description: L1/L2 Triggered Mobility (LTM) is a procedure in the 5G network that enables the UE to switch cells based on L1 and L2 triggers. It involves a series of steps, including early synchronization, LTM cell switch execution, and LTM cell switch completion, which are repeated without releasing other LTM candidate configurations after each LTM cell switch completion.
explanation: The context describes the step-by-step procedure for LTM, including the exchange of messages between the UE and gNB, such as MeasurementReport, RRCReconfiguration, and RRCReconfigurationComplete. This detailed description justifies classifying LTM as a Procedure.
