    Abstract: Systems and methods for small data transmissions (SDTs) between a user equipment (UE) and a network are disclosed herein. In some embodiments, the UE determines whether to perform an SDT procedure by comparing its own mobility state to an SDT mobility state condition provided by the network. The UE may also determine whether to perform the SDT procedure by comparing the size of user plane (UP) data to be sent with the SDT procedure to an SDT mobility-based data amount threshold provided by the network. Upon entering an RRC_INACTIVE state, the UE may start a validity timer relative to any such SDT mobility state condition and/or SDT mobility-based data amount threshold, and invalidate these once the validity timer expires. In some disclosed embodiments, the UE reports its determined mobility state to the network during an SDT procedure so that the network can accordingly select configuration parameters for SDT procedures.

    Abstract: Methods and systems are disclosed for a UE of a wireless communication network to recover from MCG radio link failures in a MR-DC system when the SCG is deactivated or otherwise not enabled. When a MCG link failure is detected and the SCG is deactivated, the UE may activate the SCG for the UE to use the SCG link to transmit and receive signaling messages or data as part of the MCG failure recovery procedure. When the MCG link failure is detected and the UE is configured to add the SCG upon the satisfaction of certain condition, but the condition has not occurred, the UE may check to determine whether one condition is MCG failure and whether the radio link quality of the SCG exceeds a threshold. If the radio link quality of the SCG exceeds the threshold, the UE may apply the SCG configuration to add the SCG.

    Abstract: This disclosure relates to a relay user equipment device (UE) assisting one or more remote UEs in performing a radio access network notification area (RNA) update procedure in a cellular communication system. The relay UE establishes a first relay connection with a first remote device. The first relay connection relays communications between the first remote device and a network. The relay UE transmits a first message to the network to initiate the RNA update procedure for the first remote device, receives an acknowledgment message from the network including updated connection information for the first remote device, and transmits the updated connection information to the first remote device.
