摘要： 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.

摘要： Systems and methods for interlace PUCCH transmission in 5G networks are described. The gNB sends an RRC message to a UE. The RRC message provides one or more PUCCH interlace allocations within a BW. Each PUCCH interlace allocation has a PUCCH format for each PUCCH interlace. Each PUCCH format contains a different PUCCH interlace index. The UE sends a PUCCH interlace in the BWP based on the PUCCH interlace allocation. A PUCCH in the allocated PUCCH interlace has a cyclic shift that is dependent on a resource block number in the allocated PUCCH interlace within the BWP.

摘要： A user equipment (UE) configured for operation in a fifth-generation new radio (5G NR) system may be configured for Type-2 Hybrid automatic repeat request (HARQ) acknowledge (ACK) (HARQ-ACK) codebook grouping and HARQ-ACK retransmission. The UE may decode a downlink control information (DCI) format for scheduling a physical downlink shared channel (PDSCH) group of one or more PDSCHs. The DCI format may include a downlink assignment index (DAI) comprising a counter DAI (C-DAI) for the scheduled PDSCH group. The DCI format may also include a total DAI (T-DAI) for at least one of the scheduled PDSCH group and a non-scheduled PDSCH group. When the DCI format includes a new feedback indicator field for at least one of the scheduled PDSCH group and the non-scheduled PDSCH group, the UE may multiplex HARQ-ACK bits only for PDSCH receptions for transmission in a PUCCH transmission occasion scheduled by the DCI format and may refrain from multiplexing HARQ-ACK bits for PDSCH receptions that are not scheduled by the DCI format. For HARQ-ACK retransmission, the UE may retransmit HARQ-ACK bits from more than one PDSCH group in the PUCCH transmission occasion.

摘要： A user equipment (UE) configured for operating in a fifth-generation (5G) new radio (NR) network may monitor search space sets for a number of physical downlink control channel (PDCCH) candidates within a number of non-overlapped control-channel elements (CCEs) for a primary cell (PCell). The number of PDCCH candidates and the number of non-overlapped CCEs may include PDCCH candidates and non-overlapped CCEs on a scheduling secondary cell (SCell). The scheduling SCell may be an SCell that schedules a transmission on the PCell. The UE may decode one or more of the PDCCH candidates on the scheduling SCell for a downlink control information (DCI) format which may schedule a physical downlink shared channel (PDSCH) transmission and/or a physical uplink shared channel (PUSCH) transmission of the PCell.

摘要： A method and apparatus for transmitting an uplink Scheduling Request (SR) are provided. The method includes, obtaining a SR subframe configuration by receiving signaling, and transmitting SR information to a Base Station (BS) by using physical resources of another non-SR channel for transmitting other uplink control information. By applying the present invention, the SR, ACKnowledgement/Non-ACKnowledgement (ACK/NACK) or Channel Quality Indicator (CQI) information is returned to a BS when low Constant Modulus (CM) characteristic of an uplink Component Carrier (CC) is ensured.

摘要： The present invention provides a method and apparatus for transmitting an ACK/NACK in a TDD system. A component carrier (CC) configuration for a user equipment (UE) and a transmission mode of each CC are received. An ACK/NACK feedback mode is selected based on an overhead status for feedback in an uplink. An ACK/NACK is processed according to the selected feedback mode. And the ACK/NACK is transmitted in the uplink. The method provided by the present invention can avoid excessive overhead for feedback in uplink in various extreme circumstances while ensuring satisfying performances of downlinks under many configurations.

摘要： A computer-readable storage medium stores instructions for execution by one or more processors of a UE to configure the UE for SBFD operation in a 5G NR network, and to cause the UE to decode RRC signaling received from a base station and including at least one CSI-RS resource set with time-frequency resource allocation associated with a CSI-RS transmission. A CSI reporting band is determined with a plurality of PRBs based on the RRC signaling. The CSI reporting band including a subset of the plurality of PRBs associated with one or more DL subband(s) in symbols or slots identified via higher layer signaling or a combination of higher layer and Layer 1 signaling for SBFD operation. Channel measurements are performed based on CSI-RSs transmitted during the CSI-RS transmission. The measurements are associated with the subset of the plurality of PRBs in the CSI reporting band.
