Abstract: Aspects of the present disclosure are to address the problems of performing time-based reconfiguration in mobile network. The method of the terminal includes receiving a first system information, receiving a second system information, determining a total amount of timing advance (TTA) based on the first NTN configuration or based on second NTN configuration and performing uplink transmission based on the TTA. The TTA is determined based on, before the stop time, the first NTN configuration and the constant offset. The TTA is determined based on, after the stop time, the second NTN configuration and the constant offset.

Abstract: A method and apparatus to enhance uplink coverage is provided. Method for enhancing uplink coverage includes receiving a SIB1 and performing a random access procedure with preamble repetition in case that Reference Signal Received Power (RSRP) of downlink pathloss reference is less than at least one of one or more thresholds related to preamble repetition. The SIB1 comprises a set of parameters related to system information scheduling and a set of parameters related to uplink configuration. Random access resource indicated in the set of parameters related to system information scheduling is used in case that the random access procedure is triggered for System Information (SI) request. Random access resource indicated in the set of parameters related to uplink configuration is used in case that the random access procedure is triggered for data transmission.
