Abstract: A UE configured for operating in a 5G NR network may decode signalling that schedules two physical downlink shared channels (PDSCHs) in a same time slot. When the UE is a reduced-bandwidth (RBW) reduced-capacity (RedCap) UE (RBW-RedCap UE), the UE may determine if a total number of allocated PRBs in an OFDM symbol for the two scheduled PDSCHs exceed a predetermined value when the two scheduled PDSCHs either partially or fully overlap in time in non-overlapping PRBs. The UE may also prioritize decoding of one of the two scheduled PDSCHs when the total number of allocated PRBs exceed the predetermined value and when the two scheduled PDSCHs either partially or fully overlap in time in non-overlapping PRBs. If a first of the two scheduled PDSCHs is a unicast PDSCH and a second of the two scheduled PDSCHs is a broadcast PDSCH, the UE may prioritize decoding of the unicast PDSCH.

Abstract: An apparatus and system of providing a listen before talk (LBT) procedure in multi-carrier or multi-beam mode above a 52.6 GHz band are described. The LBT procedure is performed independently for each carrier or beam to maintain and update a different back-off counter for each carrier or beam. To align a transmission starting time across the carriers or beams, for each carrier or beam: the counter continues to decrement if the counter has reached zero before the starting time and transmit at the starting time if the channel continues to be sensed idle for an additional observation period immediately prior to the starting time and otherwise considers the LBT procedure to have failed. The counter is reinitialized for carriers or beams for which a channel occupancy time (COT) is to be acquired and transmission ceases.

Abstract: Systems and methods for downlink transmission using a wideband unlicensed band carrier in 5G networks are described. The gNB determines, based on LBT, which LBT subchannel(s) in a BWP are available during a COT. The gNB transmits an indication of the available subchannels in DCI format 2_0 of a GC-PDCCH of one of the available subchannels and subsequently transmits a PDSCH using the available subchannel(s). The gNB may configure multiple opportunities during the COT and transmit the GC-PDCCH after the initial opportunity. The PDSCH is transmitted on all available subchannels during the COT and, during an initial portion of the COT, may transmit the PDSCH by puncturing symbols of the unavailable subchannels. The indication may include a bitmap of available subchannels or if the LBT outcome is not available, may indicate all or none of the subchannels or available or that the outcome is not available.

Abstract: A computer-readable storage medium stores instructions to configure a UE for multi-cell scheduling in a 5G NR network, and to cause the UE to perform operations including decoding higher layer signaling. The higher layer signaling indicates a number of cell groups configured to the UE. Each cell group of the number of cell groups includes at least two cells. DCI received in a PDCCH is decoded. The DCI includes a scheduling grant with time and frequency allocation for a PUSCH or a PDSCH in the number of cell groups configured to the UE. Uplink data transmissions via the PUSCH are scheduled in the number of cell groups or downlink data receptions via the PDSCH are scheduled in the number of cell groups based on the scheduling grant.

Abstract: Various embodiments may relate to physical downlink control channel (PDCCH) monitoring in association with cross-carrier scheduling. In particular, some embodiments are directed to scheduling a transmission on a primary cell (PCell) or primary secondary cell (PSCell) considering secondary cell (SCell) dormancy switching or SCell activation states. Other embodiments may be disclosed or claimed.

Abstract: A computer-readable storage medium stores instructions to configure a UE for Reduced Capability (RedCap) operation in a 5G NR network, and to cause the UE to perform operations. The operations include decoding a master information block (MIB) to determine a control resource set (CORESET) and a common search space (CSS): decoding a system information block (SIB) in a physical downlink shared channel (PDSCH) scheduled by a downlink control information (DCI) format, the DCI format received based on the CORESET and the CSS: determining an additional CORESET within a separate initial DE BWP using the SIB: and performing reception of a physical downlink control channel (PDCCH) in a PDCCH Type1 Common Search Space (CSS) set or a PDSCH associated with Random Access (RA) procedure in the separate initial DE BWP.

Abstract: An apparatus and system are described to support secondary cell (SCell) dormancy switching when cross-carrier scheduling (CCS) from SCell to primary cell (PCell) transmission is supported are described. A physical downlink control channel (PDCCH) transmission on the sSCell has a downlink control information format (DCI) format 0_1 or 1_1 containing a SCell dormancy indication field and a CIF are used to indicate CCS and SCell dormancy switching to deactivate the SCell. The CIF value is either 0 or indicates the PCell and may depend on whether physical downlink shared channel (PDSCH) transmission is scheduled. The DCI triggers bandwidth part (BWP) switching for the PCell to indicate to the UE to switch to monitoring UE-specific search space sets on the PCell instead of on the SCell.

Abstract: A computer-readable storage medium stores instructions to configure a UE for cross-carrier scheduling of data transmissions in a 5G NR and beyond wireless network, and to cause the UE to perform operations including decoding configuration signaling received from a base station. The configuration signaling indicates a first numerology parameter for a scheduling cell of the base station and a second numerology parameter for a scheduled cell of the base station. DCI is received via a PDCCH of the scheduling cell. The DCI schedules a DL data transmission in the scheduled cell of the base station. The DL data transmission is received via a PDSCH of the scheduled cell when a difference between the first numerology parameter and the second numerology parameter is smaller than or equal to a pre-configured numerology threshold value. The UE refrains from decoding the DL data transmission when the difference is greater than the threshold value.
