Section: Annex G (informative): Components of Mobility Latency
Content: HO interruption time for L1/L2-based inter-cell mobility is the time from UE receives the cell switch command to UE performs the first DL/UL reception/transmission on the indicated beam of the target cell. For Rel-18, RAN2 assumed the latency of the mobility procedure is characterized by the terms illustrated in Figure G-1. Figure G-1: Components of Mobility Latency Each component of mobility latency is described in the table below, the values of which are specified in TS 38.133[ NR; Requirements for support of radio resource management ] [13]. Table G-1: Components of Mobility Latency For Rel-18, RAN2 assumed that the latency of the RACH-based and RACH-less LTM procedure is characterized by the terms illustrated in Figure G-2 and Figure G-3. The overall mobility latency of LTM can be largely reduced by early synchronization procedure. Figure G-2: Mobility Latency for RACH-based LTM Figure G-3: Mobility Latency for RACH-less LTM
