Abstract: Title: Mobility Class-Based Timing Advance Retention Strategy for Conditional Layer Triggered Mobility (CLTM) in 5G Advanced Networks System and Method Thereof A mobility class–based timing advance lifecycle management framework for Conditional Layer 1/Layer 2 Triggered Mobility in 5G-Advanced and beyond is disclosed. A user equipment acquires early timing advance values for multiple candidate cells, determines a mobility class using network-assisted signaling and/or UE- autonomous estimation and evaluates timing uncertainty parameters including timing advance age, remaining timer value and drift indicators. Based on these parameters, the user equipment adaptively retains, releases or prunes candidate timing advance entries and dynamically selects between random-access-less and random-access-based mobility using per-candidate validity horizons and probability metrics. Upon conditional execution, the user equipment performs mobility-aware timer handling for the primary timing advance group, including reuse, translation of remaining time, conditional uplink grace operation under restrictions or conservative restart. A timing advance consistency state machine manages validity and alignment across execution and fallback, thereby reducing uplink interruption, signaling overhead and unsafe timing reuse across diverse mobility scenarios.
