    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: An example method for wireless communication includes: transmitting by a base station, to a user device in a reduced power state, resource information for receiving a channel state information reference signal (CSI-RS) and tracking reference signal (TRS); transmitting the CSI-RS and TRS based on the transmitted resource information to the user device, wherein the user device has exited the reduced power state; determining whether there is paging information to transmit in a first physical downlink shared channel (PDSCH) transmission for the user device; transmitting a downlink control information message, wherein the downlink control information message is based on the determination that there is paging information for the user device, and wherein the user device has synchronized with the base station; and transmitting the first PDSCH transmission, based on the determination that there is paging information for the user device.
