Abstract: 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.

Abstract: Various embodiments herein provide techniques for indication of a starting frequency of a control resource set (CORESET). In embodiments, two modes for determining the starting frequency are provided. An access node (e.g., next generation Node B (gNB)) may send an indication to a user equipment (UE) to indicate which mode to use (e.g., in a payload of a physical broadcast channel (PBCH)). Other embodiments may be described and claimed.

Abstract: User equipment (UE) can include processing circuitry configured to decode radio resource control (RRC) signaling from a base station, the RRC signaling indicating a transmission coding scheme for a physical uplink shared channel (PUSCH) transmission. PUSCH-to-phase tracking reference signal (PT-RS) energy per resource element (EPRE) ratio is determined using the RRC signaling. A PT-RS power boosting factor is determined based on the transmission coding scheme and the PUSCH-to-PT-RS EPRE ratio. The PT-RS is encoded for transmission using a plurality of PT-RS symbols, the transmission using increased transmission power corresponding to the PT-RS power boosting factor. The RRC signaling further includes a flag enabling the PT-RS transmission. The PUSCH-to-PT-RS EPRE ratio is 00 or 01, and the transmission coding scheme is a codebook-based uplink transmission or non-codebook-based uplink transmission.

Abstract: A user equipment (UE) can include processing circuitry coupled to memory. To configure the UE for New Radio (NR) unlicensed band (NR-U) communications, the processing circuitry is to decode downlink control information (DCI) received via a physical downlink control channel (PDCCH). The DCI provides allocation of uplink frequency resources of a transmission bandwidth. The allocation is a block interleaved frequency division multiple access (B-IFDMA) allocation including a plurality of interleaved physical resource blocks (PRBs) forming M number of interlaces within the transmission bandwidth, and N number of PRBs within each interlace of the M number of interlaces, with N and M being integers greater than or equal to 1. Data is encoded for transmission to a base station via a physical uplink shared channel (PUSCH) using the B-IFDMA allocation of uplink frequency resources.

Abstract: Technology for a user equipment (UE) to report periodic channel state information (CSI) is disclosed. The UE can generate a plurality of CSI reports for serving cells for transmission in a subframe. Each CSI report can correspond to a physical uplink control channel (PUCCH) reporting type among a plurality of CSI processes having a CSI process index (CSIProcessIndex) and a serving cell index (ServCellIndex). The UE can determine different priorities corresponding to each of the plurality of PUCCH reporting types. The UE can drop CSI reports corresponding to all CSI processes except a CSI process having the lowest CSIProcessIndex. The UE can drop CSI reports corresponding to all ServCellIndexes except a CSI report with the lowest ServCellIndex. The UE can multiplex at least one non-colliding CSI report from among CSI reports that are not dropped and hybrid automatic repeat request-acknowledgement (HARQ-ACK) feedback bits for transmission to an eNodeB.

Abstract: Embodiments of a Generation Node-B (gNB), User Equipment (UE) and methods for communication are generally described herein. The gNB may map data symbols to resource elements (REs) of virtual resource blocks (VRBs). The gNB may interleave the data symbols, on a per-VRB basis, to spatial layers of a multi-layer multiple-input multiple-output (MIMO) transmission. The data symbols may be interleaved based on different interleave patterns of VRB indexes for the spatial layers. The gNB may map the interleaved data symbols of the spatial layers to REs of physical resource blocks (PRBs) for orthogonal frequency division multiplexing (OFDM) transmission.

Abstract: Embodiments of a User Equipment (UE) and methods for device-to-device (D2D) communication are generally described herein. In some embodiments, the UE may determine a network reference timing based on a reception of a primary synchronization signal (PSS) from an Evolved Node-B (eNB). The UE may transmit a primary device-to-device synchronization signal (PD2DSS) to a second UE according to the determined network reference timing. The PD2DSS may be configured to enable synchronization for a device-to-device (D2D) communication session between the UE and the second UE. In some embodiments, the PD2DSS may be based on multiple PD2DSS symbol sequences, which may be different than PSS symbol sequences used for the PSS. In some embodiments, different Zadoff-Chu (ZC) sequences may be used for the PD2DSS and for the PSS.
