Abstract: A method and apparatus for autonomous changing for dormant bandwidth part in a wireless communication system is provided. A wireless device configures a cell group including a certain cell on which a PUCCH is configured. A wireless device activates a dormant BWP of the certain cell to be an active BWP of the certain cell, wherein no PDCCH is configured on the dormant BWP. A wireless device switches the active BWP of the certain cell from the dormant BWP to another BWP upon triggering the scheduling request procedure, wherein at least one PDCCH is configured on the other BWP.

Abstract: The present disclosure relates to handling a synchronization in wireless communications. According to an embodiment of the present disclosure, a method performed by a wireless device in a wireless communication system comprises: receiving a configuration for a master cell group (MCG) and a configuration for a secondary cell group (SCG); applying a first timing alignment (TA) for one or more cells in the SCG and skipping a physical downlink control channel (PDCCH) monitoring for the one or more cells in a first state while a TA timer is running, wherein the TA timer is started upon receiving a TA command including the first TA; performing a state switching to a second state from the first state at a time point determined based on information related to state switching time received from a network, wherein a PDCCH monitoring is performed for the one or more cells in the second state; transmitting, to the network, switching information informing the state switching; receiving, in the second state, a TA command including a second TA upon which the TA timer is restarted, after transmitting the switching information; and applying the second TA for the one or more cells while the restarted TA timer is running.

Abstract: A method and apparatus for master cell group (MCG) radio link failure (RLF) reporting during secondary cell group (SCG) suspension in a wireless communication system is provided. A wireless device detects a failure on a master cell group (MCG) while a secondary cell group (SCG) is suspended, and transmits MCG failure information informing the failure on the MCG by using a physical uplink control channel (PUCCH) format via the SCG, based on unavailability of physical uplink shared channel (PUSCH) transmission via the SCG.

Abstract: The present disclosure relates to a method of performing data transmissions in a Radio Resource Control (RRC) INACTIVE state by a user equipment (UE) in a wireless communication system. Especially, the method includes the steps of performing a Short Data Transmission (SDT) procedure for transmitting a data unit in the RRC INACTIVE state; based on a failure of the SDT procedure being detected, determining whether a radio bearer (RB) of at least one logical channel related to the data unit is Acknowledged Mode (AM) RB or not; based on the RB not being the AM RB, discarding the data unit; and based on the RB being the AM RB, transmitting a RRC message to the network for requesting RRC connection resumption and performing the retransmission of the data unit in a RRC CONNECTED state.
