Abstract: A user equipment (UE) may establish a radio resource control (RRC) connection with a first cell of a cellular network and transmit signaling comprising an indication of enhanced radio link failure (RLF) recovery capability. The UE may receive one or more RRC messages comprising configuration information for RLF recovery on the first cell. The UE detect one or more RLFs corresponding to the first cell and further determine, via a connection reestablishment cell selection procedure, that the first cell is a suitable RLF recovery candidate cell. In response to the detection and determination, the UE may apply the configuration information for the first cell. The UE may then transmit signaling comprising a trigger indicating a RLF recovery to the cellular network and re-establish the RRC connection with the cellular network using the configuration information.

Abstract: Techniques discussed herein facilitate cell selection and/or reselection in scenarios involving one or more Non-Terrestrial Network (NTN) cells. One example embodiment is a User Equipment (UE) device comprising a processor configured to perform operations comprising: determining one or more suitable cells for one of a cell selection procedure or a cell re-selection procedure, wherein the one or more suitable cells comprise a first cell associated with a satellite of a NTN; determining a ranking for each cell of the one or more suitable cells, wherein the ranking for the first cell is based at least in part on a location of the UE, ephemeris data of the satellite, and one or more additional parameters; selecting a highest ranked cell of the one or more suitable cells based on the determined rankings for each cell of the one or more suitable cells; and camping on the highest ranked cell.

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: Embodiments are presented herein of apparatuses, systems, and methods for a user equipment device (UE) and a network to perform closed-loop transmission power control in a multi-base station environment with out-of-order scheduling. The network may configure a series of transmission power control commands to indicate to the UE transmission power for one or more transmissions to different base stations. The UE may receive the transmission power control commands, consider information including timing and/or resources associated with the transmission power control commands, and determine transmission power for the transmissions.
