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： 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) 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.

摘要： 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. 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.

摘要： Embodiments of a user equipment (UE) configured for new-radio (NR) operations in a fifth-generation (5G) system (5GS) may be configured to detect a downlink-control information (DCI) format that includes a one-shot hybrid automatic repeat request acknowledgement (HARQ-ACK) request field and a frequency domain resource assignment field (FDRA). The one-shot HARQ-ACK request field may indicate whether one-shot HARQ-ACK feedback is triggered. The UE may decode the FDRA field to determine whether the FDRA field indicates a valid frequency resource or whether the FDRA field indicates a special value and may also be configured to determine whether or not a physical downlink shared channel (PDSCH) is scheduled by the DCI format and whether or not secondary cell (SCell) dormancy switching is triggered based on both the one-shot HARQ-ACK request field and the FDRA field. The UE may also encode a HARQ-ACK transmission on a physical uplink control channel (PUCCH). The HARQ-ACK transmission may be encoded to include HARQ-ACK feedback for PDSCH transmissions for all HARQ processes of a cell when the one-shot HARQ-ACK feedback is triggered.

摘要： Systems for providing coverage enhancement for Msg 3 PUSCH and PUCCH carrying the HARQ-ACK for Msg4 of PRACH initial access are described. The gNB provides a 2-bit aggregation factor for transmission of the Msg3 PUSCH in an RAR UL grant field. The PUSCH frequency resource allocation field is limited to 12 bits so that the RAR has an overall number of bits that is the same as an RAR that does not contain the aggregation factor. A default PUSCH TDRA table includes a field to indicate a repetition level for Msg3 PUSCH transmission. For retransmissions, fields in DCI format 0_0 are repurposed to indicate an aggregation factor. Inter-slot frequency hopping may be configured by higher layers. Different PRACH resources are used to indicate UE coverage status.
