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.

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 disclosed herein. The UE may attempt to decode sidelink synchronization signals (SLSSs) received on component carriers (CCs) of a carrier aggregation. In one configuration, synchronization resources for SLSS transmissions may be aligned across the CCs at subframe boundaries in time, restricted to a portion of the CCs, and restricted to a same sub-frame. The UE may, for multiple CCs, determine a priority level for the CC based on indicators in the SLSSs received on the CC. The UE may select, from the CCs on which one or more SLSSs are decoded, the CC for which the determined priority level is highest. The UE may determine a reference timing for sidelink communication based on the one or more SLSSs received on the selected CC.

Abstract: This disclosure relates to implementations to support non-UE-specific (i.e. common) and UE-specific search spaces (SS) for M-PDCCH. One implementation relates to a UE comprising RF circuitry to receive, from an eNB, configuration information of one or a plurality of common Search Spaces (CSSs) for M-PDCCH; and baseband circuitry to monitor the one or more configured CSS for M-PDCCH transmissions; wherein the RF circuitry and/or baseband circuitry is adapted to support a reduced bandwidth (BW). Another implementation relates to an eNB comprising RF circuitry to transmit configuration information of a plurality of CSSs for M-PDCCH to one or more UEs supporting a reduced BW, wherein the plurality of CSSs for M-PDCCH are differentiated by “based on functionality”-differentiation that includes the type of use case and/or an EC level of the UE.
