    Abstract: Methods and apparatus for Timing Advance (TA) validation are disclosed. In some embodiments, a method for wireless communication at a user equipment (UE) comprises receiving, from a base station, configuration information, where the configuration information specifying a configured grant (CG)-small data transfer (SDT) resource available for use by the UE and specifying a configuration for a Reference Signal Received Power (RSRP) change-based TA validation method to be met in order to perform a SDT while in the RRC inactive state, the RSRP change-based TA validation method having configured TA validation criteria that is evaluated based on two measurement windows for timing advance (TA) validation, and at least one boundary of at least one of the two measurement windows for TA validation is based on a minimum of either a Frequency Range 2 (FR2) measurement period and a scaled Discontinuous Reception (DRX) cycle period, existing at time of TA validation criteria evaluation.
