  • Publication number: 20240373383
    Abstract: A wireless communication method for execution by a user equipment (UE) is provided. The UE receives a radio resource control (RRC) message used for transiting the UE to an RRC inactive state and starts a small data transmission (SDT) time alignment timer (TAT) upon receiving the RRC message. The UE determines whether timing alignment (TA) for the UE is validated through TA validation at least based on the TAT and at least one measurement of reference signal received power (RSRP) compared to at least one RSRP associated threshold. The UE transmits uplink small data on pre-configured SDT resources in the RRC inactive state of the UE when the TA for the UE is validated through TA validation.
