Abstract: A method (700) by a user equipment, UE, (112, 200) for facilitating long uplink transmission in an Internet of Things, IoT, Non-Terrestrial Network, NTN, includes transmitting (702), to a network node (110, 300), information for determining whether the UE is to insert at least one gap between adjacent transmission segments in at least one uplink transmission. The UE receives (704), from the network node, configuration information configuring the UE to insert the at least one gap when the information transmitted to the network node indicates that at least one symbol, slot, and/or subframe is to be dropped and/or punctured to implement segmented pre-compensation or not insert the at least one gap when the information transmitted to the network node indicates that at least one sample is to be dropped and/or punctured to implement segmented pre-compensation.

Abstract: A method and network node for handling survival time during handover are disclosed. According to one aspect, a method in a network node includes receiving a handover request from a source network node. The method also includes determining whether a time sensitive communication assistance information (TSCAI) of the WD 5 indicates a survival time. The method further includes when the TSCAI indicates a survival time, then allocating radio resources to the WD based at least in part on the survival time.

Abstract: Systems and methods for signaling of traffic flow information for Discontinuous Reception (DRX) configuration are provided. A method of operating a UE for determining a flow type includes: receiving a configuration of flow identify information with an association between one or more of: Downlink Control Information (DCIs); Radio Network Temporary Identifier (RNTIs); a combination of fields; with one or more DRX configurations; monitoring a Physical Downlink Control Channel (PDCCH) in DRX Active Time; in response to receiving a PDCCH with DCI indication of a flow type, identifying the DRX configuration k associated to the DCI indication; and starting or restarting a corresponding timer in the next symbol after PDCCH reception. In this way, signaling for a flow type, DRX configuration, or DRX parameter value indication from a gNB to a UE can be provided, in order to optimize multiple DRX cycle configurations per Serving Cell, where one or more of the configurations are active simultaneously.

Abstract: The present disclosure relates to adaptive signal strength thresholds and other parameters to support reduced capability UEs. In embodiments of the present invention, a UE receives a first signal strength threshold value from a network node, and, from the received first signal strength threshold value, the UE derives a second signal strength threshold value associated with a receiver configuration supported by the UE for performing a radio procedure. The derived second signal strength threshold value is used when performing the radio procedure.

Abstract: Methods and apparatus are provided. In an example aspect, a method of correcting one or more errors in a received word is provided. The received word comprises one or more symbol labels. The method comprises modifying a first symbol label in the received word to a first alternative symbol label corresponding to a symbol in a symbol constellation that is one of a closest one or more symbols to a symbol corresponding to the first symbol label to form a first modified word, and determining whether the first modified word is a valid codeword. In some examples, the disclosed techniques may be used to implement a noise guesser adapted to higher-order, Gray-labeled signal constellations to be used for Guessing Random Additional Noise Decoding, GRAND.

Abstract: A method, performed by a first network node (111). The method is for handling Doppler shift pre-compensation. The first network node (111) sends (401) a first indication towards a first wireless device (131). The first indication indicates a start of a training phase. The first network node (111) obtains (403), based on the sent first indication, a set of information from the first wireless device (131). The set of information indicates: i) a Doppler shift experienced by the first wireless device (131) while moving along a pre-defined trajectory (140) to which a static set of radio network nodes (120) provide coverage, and ii) a set of features characterizing how the first wireless device (131) experienced the Doppler shift. The first network node (111) also initiates (404) determining, using machine-learning, and based on the received set of information, a predictive model of Doppler shift pre-compensation. The training phase is of the predictive model.
