    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 confirmation 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 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: Systems, devices, and techniques for transmit power control (TPC) in wireless communication systems are described. A described technique performed by a user equipment (UE) includes signaling that enables transmit power control (TPC) accumulation; receiving, by the UE, downlink control information (DCI) messages corresponding to respective physical uplink shared channel (PUSCH) transmission occasions; determining, by the UE, power control adjustment states for the PUSCH transmission occasions; and transmitting, by the UE, in the PUSCH transmission occasions in accordance with the power control adjustment states. Determining the power control adjustment states can include selectively applying TPC accumulation to one or more of the power control adjustment states based on a determination that at least one of the PUSCH transmission occasions is out-of-order based on an arrival ordering of the DCI messages.

    Abstract: The disclosure describes mechanisms for reliability enhancement on control channel and data channel and mechanisms in URLLC. An apparatus of a RAN node for URLLC includes baseband circuitry to configure at least one DCI for scheduling transmission of at least one PDSCH content having same information. For each DCI, the baseband circuitry determines a CORESET for transmitting the DCI. The disclosure further describes mechanisms for the support of low latency transmission in URLLC. To improve peak data rate and spectrum efficiency in FDD system, the RAN node configures a DCI for scheduling data transmission using blank resources of a self-contained slot structure. Further, CBG-based transmission with separate HARQ-ACK feedback is provided to configure a DCI for scheduling data transmission of a TB and to divide the TB into multiple CBGs, and to configure uplink control data to carry separate HARQ feedback for the CBGs.
