Original Abstract Submitted

systems and methods for performing timing advance (ta) validation at a user equipment (ue) for a ta to be used when transmitting a configured grant small data transmission (cg-sdt). mechanisms for bounding one or more measurement windows during which one or more synchronization signal blocks are measured during a reference signal received power (rsrp) measurement method of the ta validation are discussed, and may be set using information corresponding to timing drift due to relativistic effects, clock differences between a ue and a base station, and/or information about a ue discontinuous reception (drx) cycle. further, time interval limitations between various events attendant to such an rsrp measurement method are discussed as being determined using information corresponding to timing drift due to relativistic effects, clock differences between a ue and a base station, information about a drx cycle used at the ue, and/or a maximum ta timer duration.
