    Abstract: Embodiments of a Generation Node-B (gNB), User Equipment (UE) and methods for communication are generally described herein. The gNB may allocate a resource pool of physical resource blocks (PRBs) and sub-frames for vehicle-to-vehicle (V2V) sidelink transmissions. The gNB may receive, from a UE, an uplink control message that indicates that the UE requests a V2V sidelink transmission of a prioritized message. The gNB may select, for the V2V sidelink transmission of the prioritized message, one or more PRBs and one or more sub-frames. The gNB may transmit, to the UE and to other UEs, a downlink control message that indicates: the selected PRBs, the selected sub-frames, and that the other UEs are to mute sidelink transmissions in the selected PRBs in the selected sub-frames to enable the V2V sidelink transmission of the prioritized message.

    Abstract: User equipment (UE) includes processing circuitry, where to configure the UE for New Radio (NR) communications in an unlicensed spectrum, the processing circuitry is to decode a first configuration message received from a base station, the first configuration message including a channel quality indicator (CQI) table indication identifying a CQI table. A second configuration message is decoded, the second configuration message received separately from the first configuration message and including a modulation and coding scheme (MCS) table indication identifying an MCS table. DCI received via a PDCCH is decoded, the DCI providing a DL grant and an MCS index in the MCS table. DL information received via a PDSCH is decoded using modulation order and target code rate corresponding to the MCS index in the MCS table.

    Abstract: A user equipment (UE), gNodeB or network component can be configured to support Quality of Service (QoS) aware sidelink communications for vehicle to everything (V2X) communication operations. The QoS aware sidelink communications can include operating QoS congestion control, QoS control and adaptation, QoS aware resource allocation, QoS aware in-device coexistence operations, as well as sensing and reservation based on sidelink resource allocations. Transmitter constraints can be provided according to a Quality of Service (QoS) aware congestion control that enables a fair usage of spectrum resources with one or more V2X devices, based on QoS attributes. Different V2X packets can be scheduled/filtered based on combinations of the QoS attributes. A priority of one radio access technology (RAT) over another can be made based on the QoS attributes associated with the different V2X packets being delivered in sidelink transmissions for a QoS aware in-device coexistence operation.

    Abstract: A network device (e.g., a user equipment (UE), a new radio NB (gNB), or other network component) can process or generate a dynamic Physical Uplink Shared Channel (PUSCH) repetition indication that provides parameters about PUSCH repetition(s) for the uplink within one, two or other number of slots of a New Radio (NR) communication as an Ultra-Reliable Low-Latency Communication. The network device can also process or generate one or more multiple Configuration-Grant (CG) PUSCH configurations. The presence of a repetition level bit-field in a Downlink Control Information (DCI) carrying UL grant or activating UL configured grant PUSCH can be controlled by semi-static UE-specific RRC signaling enabling or disabling the dynamic signaling of PUSCH repetitions.
