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: An apparatus of a user equipment (UE) includes processing circuitry, where to configure the UE for New Radio (NR) communications above a 52.6 GHz carrier frequency, the processing circuitry is to decode higher layer signaling, the higher layer signaling including a default slot duration for a transmission of control signaling. The control signaling includes a synchronization signal (SS) and a physical broadcast channel (PBCH) signaling. Synchronization information within a SS block is decoded. The SS block is received within a SS burst set and occupying a plurality of symbols within a slot having the default slot duration. A synchronization procedure is performed with a next generation Node-B (gNB) based on the synchronization information within the SS block and the PBCH signaling.

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: 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 SIM 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.
