Abstract: Systems, methods, and circuitries are provided for maximizing use of discovery reference (DRS) resources for remaining minimum system information (RMSI) allocation. An example method includes configuring Type 0 physical downlink control channel (PDCCH) CORESET monitoring to include monitoring in either a first slot or a first slot and a second slot; generating a synchronization signal block (SSB) encoding the configured PDCCH CORESET monitoring; and transmitting the SSB to a user equipment (UE) by way of a discovery reference signal (DRS).

Abstract: A user equipment (UE) may include one or more processors that are configured to cause UE capability information to be communicated to a radio access network (RAN) node, regarding a maximum number of blind decode attempts (BDAs) supported by the UE. The one or more processors are configured to determine, based on the maximum BDAs, shortened channel control elements (sCCEs) to be used, by the RAN node, to transmit shortened downlink control information (sDCI) via a shortened physical downlink control channel (sPDCCH) and obtain sDCI by monitoring the sPDCCH in accordance with the determined sCCEs.

Abstract: In a general aspect, a User Equipment (UE) in a cellular communications network receives a Radio Resource Control (RRC) signaling message from a base station communicatively coupled to the UE over a communications channel. The UE accesses a search space in the RRC signaling message. The UE identifies a fallback Downlink Control Information (DCI) Information Element (IE) included in the search space. The UE determines whether an aggregation factor is indicated in the fallback DCI IE for shared channel communications with the base station, over multiple slots in the communications channel. The UE determines an uplink/downlink (UL/DL) configuration for transmission on the communications channel. The UE schedules an aggregated transmission over multiple slots in the communications channel based on the aggregation factor and the uplink/downlink configuration.

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 of a User Equipment (UE), generation Node-B (gNB) and methods of communication are generally described herein. The UE may receive a narrowband physical downlink control channel (NPDCCH) that includes an uplink scheduling parameter. The UE may determine an uplink scheduling delay for transmission of a narrowband physical uplink shared channel (NPUSCH) in accordance with time-division duplexing (TDD). The uplink scheduling delay may be based on a sum of a predetermined first number of subframes and a variable second number of subframes. The second number of subframes may be based on a window of variable size that starts when the first number of subframes has elapsed since reception of the NPDCCH, and ends when a number of uplink subframes has elapsed since the start of the window. The number of uplink subframes may be indicated by the uplink scheduling parameter.

Abstract: Embodiments of a User Equipment (UE), Generation Node-B (gNB) and methods of communication are disclosed herein. The UE may receive a physical downlink control channel (PDCCH) that schedules a physical downlink shared channel (PDSCH) in a slot, and on a component carrier (CC) of a plurality of CCs, The PDCCH may include a total downlink assignment index (DAI) and a counter DAI for hybrid automatic repeat request acknowledgement (HARQ-ACK) feedback of the PDSCH. The total DAI may indicate a total number of pairs of CCs and slots for the HARQ-ACK feedback. The UE may encode the HARQ-ACK feedback to include a bit that indicates whether the PDSCH is successfully decoded. A size of the HARQ-ACK feedback may be based on the total DAI, and a position of the bit may be based on the counter DAI.
