Abstract: The present disclosure relates to a time alignment timer handling in wireless communications. According to an embodiment of the present disclosure, a user equipment (UE) may initiate a transmission of failure information for a cell group based on detecting a failure on the cell group. The UE may consider a time alignment (TA) timer related to a TA configuration for the cell group as expired based on initiating the transmission of the failure information. After transmitting the failure information, the UE may receive a configuration for failure recovery of the failure on the cell group. The UE may restart the TA timer related to the TA configuration for the cell group based on receiving the configuration for failure recovery.

Abstract: A method and apparatus for enhancing a handover procedure for supporting conditional handover in a wireless communication system. A source base station (e.g. source gNB/eNB) receives a message informing that a wireless device is handed over from the source base station to a target base station (e.g. target gNB/eNB). The target base station is one of candidate target base stations in the conditional handover procedure. After receiving the message, the source base station transmits a sequence number (SN) status transfer message to the target base station.
