    Abstract: Systems and methods for performing measurements of one or more cells during an small data transmission (SDT) procedure between a user equipment (UE) and a network when the UE is in a radio resource control (RRC) INACTIVE state are described herein. Beam and/or cell measurements taken during an SDT measurement period of the SDT procedure may be used to determine one or more respective cell qualities, among other possibilities. Beginnings and endings of the SDT measurement period, and the manner (timing) for taking measurements within the SDT measurement period, are also described. The cell qualities so determined can then be used to monitor, during the SDT measurement period, for a measurement event, which causes the UE to send a measurement report to the network having data determined using those cell qualities, and/or to send messaging intended to induce the network to change the RRC state of the UE.

    Abstract: Transmission occasions in a multi-PUSCH CG cycle can be identified as unused transmission occasions (UTOs) or used transmission occasions. HARQ PIDs for transmission occasions of the multi-PUSCH CG cycle can be determined prior to processing the first PUSCH. UTOs among all transmission occasions of the multi-PUSCH CG cycle can be determined based on a CG timer associated with the HARQ PIDs, status of a logical channel buffer associated with the multi-PUSCH CG, and prioritization of additional grants. HARQ PIDs can be remapped or changed to no longer be blocked by the CG timer. Overlapping transmission occasions of other grants may or may not be prioritized based on whether they overlap with multi-PUSCH CG transmission occasions already identified as UTOs. The use status of the transmission occasions can be reevaluated when certain conditions are met. Base stations can automatically refrain from decoding multi-PUSCH CG transmission occasions blocked by a CG timer.

    Abstract: This disclosure relates to techniques for handling timing alignment for configured grant based small data transmissions in inactive mode in a wireless communication system. A wireless device may establish a radio resource control connection with a cellular base station. The wireless device may receive an indication to release the radio resource control connection. The indication to release the radio resource control connection may configure resources for performing uplink transmissions while in the radio resource control inactive mode. A timing advance may be maintained while in the radio resource control inactive mode. An uplink transmission may be performed using resources configured for performing uplink transmissions while in the radio resource control inactive mode. The uplink transmission may be performed using the timing advance.

    Abstract: While in an inactive state, a user equipment (UE) device transmits a message to a base station. The message indicates the UE device's intent to perform transmission and/or reception of user data with the network during the inactive state. The message may include a portion of the user data and/or a buffer status report. The UE device receives a response message that induces a state transition in the UE device. Different state transitions (e.g., to idle, inactive, legacy inactive, connected) may be induced by different types of response message (e.g., release, release with suspend configuration, resume, setup). One particular type of response message causes the UE to stay in the inactive state and enables subsequent user data transmission/reception in the inactive state. The response message may implicitly (or explicitly) indicate that forwarding of the user data to a core network was successful.
