Abstract: Systems, apparatuses, methods, and computer-readable media are provided for dynamic hybrid automatic repeat request (HARQ)-acknowledgement (ACK) feedback for multi-cell scheduling (e.g., a downlink control information (DCI) that schedules physical downlink shared channels (PDSCHs) and/or physical uplink shared channels (PUSCHs) on multiple cells). Embodiments may include techniques to determine a downlink assignment index (DAI) and/or a HARQ-ACK codebook, e.g., a Type-1. Type-2, and/or Type-3 codebook, for multi-cell scheduling. Other embodiments may be described and claimed.

Abstract: A generation-Node B (gNB) configured for unlicensed spectrum operation above 52.6 GHz in a fifth-generation new-radio (NR) system (5GS) may encode a parameter (e.g., ssb-PositionsInBurst) for transmission to a UE (e.g., in the SIB1 or UE specific RRC signalling). The parameter may indicate candidate positions of synchronization signal blocks (SSBs) within a discovery reference signal (DRS) measurement timing configuration (DMTC) transmission window within slots of a system frame (SFN). During the DMTC window, the gNB may perform a LBT procedure on an unlicensed carrier of the unlicensed spectrum to determine if the unlicensed carrier is available. When the LBT is successful (i.e., the unlicensed carrier is available), the gNB may encode a discovery reference signal (DRS) for transmission on the unlicensed carrier. The DRS may include one or more of the SSBs transmitted during the candidate positions that fall within the DRS. The gNB may perform rate matching around the SSBs for a scheduled PDSCH based on the indicated parameter and transmit the rate-matched PDSCH.

Abstract: An apparatus and system of providing resource allocation for PDSCH and/or PUSCH transmissions with multi-cell scheduling are described. For multi-cell scheduling, one or more of a carrier indicator, bandwidth part (BWP) indication, UL/SUL indicator, frequency domain resource allocation (FDRA) and/or time domain resource allocation (TDRA) may be provided by a NG-RAN node to a UE. In some cases, a carrier indication bitmap may be provided in downlink channel information to indicate single or multi-cell scheduling, as well as the scheduled cells.

Abstract: A UE configured for operation in a 5GNR system may decode a first DCI scheduling a first PUSCH transmission with transport-block processing over multiple slots (TBoMS) and a second DCI scheduling a second PUSCH transmission with TBoMS. The UE may check timing relations of the scheduled first and second PUSCH transmissions with TBoMS for validity. When the timing relations are valid, the UE may transmit the first PUSCH transmission in multiple slots in accordance with the first DCI and may transmit the second PUSCH transmission in multiple slots in accordance with the second DCI. The first DCI may be received in a first PDCCH and the second DCI may be received in a second PDCCH. When the first PDCCH ends at a first symbol and the UE is scheduled to start the first PUSCH transmission with TBoMS at a second symbol, the second PUSCH transmission with TBoMS is not expected to be scheduled to start earlier than an end of the first PUSCH transmission with TBoMS when the second PDCCH that scheduled the second PUSCH transmission with TBoMS ends at a symbol later than the first symbol.

Abstract: A user equipment (UE) configured for operation in a 5th generation (5G) new radio (NR) system (5GS) (5G NR) in which a multi-transmission time interval (TTI) DCI schedules multiple physical downlink shared channels (PDSCHs), generates a Type-1 HARQ-ACK codebook for candidate PDSCH reception occasions corresponding to an uplink slot. The UE determines a set of downlink (DE) slots for the multiple scheduled PDSCHs and a set of a Start and Length Indicator Values (SLIVs) for the DE slots based on configured slot timing values (K1) and a configured time domain resource allocation (TDRA) table.

Abstract: A user equipment (UE) for operation in a fifth-generation new radio (5G NR) network may be configured with two or more secondary cells (SCells) of a group of SCells. In these embodiments, the UE may monitor a physical downlink control channel (PDCCH) for detection of a downlink control information (DCI) format 1_1. The UE may interpret the DCI format 1_1 as indicating SCell dormancy, rather than scheduling a physical downlink shared channel (PDSCH) reception, if the UE is configured with resourceAllocationType1 and if all bits of a frequency domain resource assignment field in the DCI format 1_1 are equal to 1. For SCell dormancy, the UE may interpret fields of the DCI format 1_1 as a bitmap for SCell dormancy indication and either activate or deactivate a downlink bandwidth part (DL BWP) for an SCell of the group of configured SCells when indicated by the bitmap.
