Abstract: A device of a New Radio (NR) User Equipment (UE), a method and a machine readable medium to implement the method. The device includes a Radio Frequency (RF) interface, and processing circuitry coupled to the RF interface, the processing circuitry to: determine that the UE is configured with a feature of multiple Physical Uplink Control Channel (PUCCH) resources with HARQ-ACK feedback within a slot; determine a Physical Uplink Control Channel (PUCCH) resource to carry Hybrid Automatic Repeat Request Acknowledgment (HARQ-ACK) feedback in response to a scheduled Physical Downlink Shared Channel (PDSCH) resource; and encode for transmission to a NR evolved NodeB (gNodeB) the PUCCH resource, the PUCCH resource to carry the HARQ-ACK feedback and: another PUCCH resource carrying Uplink Control Information (UCI) other than HARQ-ACK feedback, and a scheduled Physical Uplink Shared Channel (PUSCH) resource.

Abstract: Systems, devices, and techniques for preemption indication in wireless communication systems are described. A described technique includes receiving, by a User Equipment (UE) via a physical downlink control channel (PDCCH), a downlink control information (DCI) message in a Control Resource Set (CORESET) configured with a transmission configuration indicator (TCI) state, the TCI state being associated with a transmission reception point (TRP), the DCI message comprising a downlink preemption indication for the TCI state; and applying preemption to a reference signal or a channel associated with the TCI state responsive to the downlink preemption indication.

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 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.

Abstract: Systems, Methods, Devices, and Apparatuses for power saving are provided. In at least one embodiment, a device may be configured for discontinuous reception (DRX) mode and further receive signaling indicating whether or not to wake and/or may receiving signaling indicating whether or not to go-to-sleep. The signaling may be implemented as group-specific signaling.

Abstract: Embodiments of the present disclosure describe methods, apparatuses, storage media, and systems for determining a capability of a UE to support a first downlink control information (DCI) format for Physical Downlink Shared Channel (PDSCH) reception in a downlink (DL) bandwidth part (BWP) and a second DCI format for scheduling uplink (UL) grants for physical uplink shared channel (PUSCH) transmission in a UL bandwidth part (BWP), where the first DCI format is different from DCI formats 1_0 or 1_1, and the second DCI format is different from DCI formats 0_0 or 0_1. Furthermore, a base station may determine search spaces for monitoring physical downlink control channel (PDCCH) candidates to obtain DCI formats indicated by the base station. Other embodiments may be described and claimed.

Abstract: A method for enhanced physical uplink shared channel (PUSCH) repetitions includes receiving at least one of a dynamic grant or a configured grant for an uplink transmission, determining a time domain resource allocation (TDRA) for repeated transmission of the uplink transmission on a PUSCH, and repeatedly transmitting the uplink transmission based on the TDRA.

Abstract: Methods, systems, apparatus, and computer programs, for activating cross-slot scheduling in user equipment (UE) to achieve power savings. In one aspect, the method can include actions of generating, by an access node, an RRC communication including one or more parameters that, when processed by the UE, configures the UE to forego use of computing resources to buffer for potential PDSCH transmission for a predetermined amount of time, encoding, by the access node, the RRC communication for transmission to the UE, and causing, by the access node, one or more antennae to transmit the encoded RRC communication to the UE.
