Abstract: An apparatus is configured to be employed within a user equipment (UE) device. The apparatus comprises baseband circuitry which includes a radio frequency (RF) interface and one or more processors. The one or more processors are configured to identify a plurality of monitoring occasions for a set of flexible control resource sets (CORESET); determine bit ordering for the plurality of monitoring occasions; generate hybrid automatic repeat request (HARQ) feedback based on the received downlink transmission; and incorporate the ordered plurality of monitoring occasions into the HARQ feedback.

Abstract: Systems, apparatus, user equipment (UE), evolved node B(eNB), and methods are described for machine-type communications (MTC) with early termination of repeated transmissions. In MTC implementations with narrow bandwidth, significant numbers of retransmissions may be scheduled based on channel quality measurements. If data is successfully decoded at a receiving device while a significant number of retransmissions remain, system resources are wasted. Embodiments described herein thus use downlink control messaging or intermediate hybrid automatic repeat request (HARQ) messaging for early termination of repeated messages.

Abstract: Technology for a user equipment (UE), configured for coverage enhanced (CE) machine type communication (MTC) is disclosed. The UE can encode, at the UE, a UE capability message for transmission to a next generation node B (gNB) or evolved Node B (eNB), wherein the UE capability message includes a capability to support communication using a modulation and coding scheme (MCS) that includes 64 quadrature amplitude modulation (QAM). The UE can decode, at the UE, a higher layer signaling message to configure the UE to operate in a CE mode A. The UE can decode, at the UE, data received in a physical downlink shared channel (PDSCH) transmission to the UE that is modulated using a 64 QAM.

Abstract: Technology for a user equipment (UE) operable to determine a transport block size (TBS) is disclosed. The UE can determine a number of assigned resource elements (REs) in one or more symbols for a transport block. The UE can determine a reference number of REs per physical resource block (PRB) in the transport block based on a reference number of REs for the transport block corresponding to each PRB and an assigned number of PRBs for the transport block. The UE can determine a TBS for the transport block based at least on the reference number of REs per PRB in the transport block. The UE can encode information in a selected transport block for transmission via a physical uplink shared channel (PUSCH) to a Next Generation NodeB (gNB) in accordance with the TBS determined at the UE.

Abstract: A method of support of aggressive user equipment (UE) minimum processing times for physical downlink shared channel (PDSCH) processing and physical uplink shared channel (PUSCH) preparation in new radio (NR) is disclosed. The method includes indicating or causing to indicate a capability from the UE to the network in the form of capability reporting for support of Capability 2 processing times, and multiplexing or causing to multiplex scheduling instances with Capabilities 1 or 2 based on the indication. The method also includes applying or causing to apply a relaxation to the minimum UE processing times, N1, indicating time between end of PDSCH to earliest start of corresponding hybrid automatic repeat request-acknowledge (HARQ-ACK) feedback transmission when the PDSCH has specific durations and/or mapping types or has time-domain overlaps with the scheduling physical downlink control channel (PDCCH). A corresponding apparatus and non-transitory computer readable medium are also disclosed.

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.

Abstract: Embodiments described herein related generally to techniques for device discovery for device-to-device (D2D) communications. A user equipment (UE) may receive a transmission probability (e.g., from an evolved Node B (eNB)) for transmission of a discovery medium access control (MAC) protocol data unit (PDU) for D2D communications. The UE may determine a pseudo-random number based on an identifier of the UE, information in the discovery MAC PDU, or information associated with a discovery period. The UE may compare the pseudo-random number with the transmission probability to determine whether to transmit the discovery MAC PDU in the discovery period. Another UE may also determine the pseudo-random number to determine whether the UE is to transmit the discovery MAC PDU in the discovery period. Other embodiments may be described and claimed.
