Abstract: Technology for a user equipment (UE) operable for interrupted transmission indication is disclosed. The UE can be configured to decode, at the UE, control information carried by a physical downlink control channel (PDCCH) in a first active bandwidth part (BWP). The UE can be configured to identify, at the UE, an interrupted transmission (INT) indicator from the control information in the first active BWP. The UE can be configured to determine, at the UE, a location of an INT indicator for a second active BWP from the INT indicator for the first active BWP.

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: Embodiments of an eNB to operate in accordance with a coverage enhancement mode are disclosed herein. The eNB may comprise hardware processing circuitry to, during a legacy sub-frame, transmit a system information block (SIB) in legacy SIB frequency resources according to a legacy SIB transmission format and refrain from transmission of channel state information reference signals (CSI-RS). The hardware processing circuitry may be further to, during a first coverage enhancement sub-frame, transmit a first portion of the SIB in first SIB frequency resources included in the legacy SIB frequency resources. The hardware processing circuitry may be further to, during a first coverage enhancement sub-frame, transmit a first set of CSI-RS in first CSI-RS frequency resources that include at least a portion of the legacy SIB frequency resources.

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: A network device (e.g., a user equipment (UE), or a new radio NB (gNB)) can process or generate a configuration of a multi-subframe scheduling signal to configure an unlicensed band transmission that comprises an hybrid automatic repeat request (HARQ) feedback or a plurality of time transmission intervals (TTIs). The unlicensed band transmission can be configured dynamically with a number of N subframes, N comprising an integer greater than one, based on a downlink control information (DCI) or a radio resource control (RRC) signaling, which comprises the one or more subframes of the multi-subframe scheduling signal.

Abstract: Embodiments of a User Equipment (UE), Next Generation Node-B (gNB) and methods of communication are generally described herein. The UE may receive radio resource control (RRC) signaling that configures reception of a plurality of physical downlink shared channels (PDSCHs) in a frame. The frame may comprise multiple slots, including one or more downlink slots and one or more uplink slots. The UE may determine a subset of the PDSCHs, such that for each of the PDSCHs of the subset, corresponding consecutive slots do not overlap the uplink slots. The UE may set a number of bits of a hybrid automatic repeat request acknowledgement (HARQ-ACK) codebook equal to a number of PDSCHs in the determined subset.

Abstract: Technology for a UE is disclosed. The UE can identify that a resource for a PUCCH transmission with HARQ-ACK information and/or a resource for a PUCCH associated with a SR overlap in time with two resources for respective PUCCH transmissions with two CSI reports. The UE can select a resource for a PUCCH transmission with a CSI report having a higher priority from the two resources for respective PUCCH transmissions with the two CSI reports. The UE can multiplex the HARQ-ACK information and/or the SR in the selected resource for the PUCCH transmission with the CSI report having the higher priority. The UE can encode the multiplexed HARQ-ACK information and the SR and the CSI report for transmission on the selected resource for the PUCCH transmission to a NR base station. The UE can drop the CSI report and the PUCCH resource having a lower priority.

Abstract: Embodiments of a User Equipment (UE) to operate in accordance with a physical random access channel (PRACH) are disclosed herein. The UE may comprise hardware processing circuitry to determine a coverage enhancement category for the UE based on downlink channel statistics related to reception of downlink signals at the UE from an Evolved Node-B (eNB) and an uplink-downlink imbalance parameter related to uplink reception at the eNB. The hardware processing circuitry may be further to select, for use in a coverage enhancement mode, a PRACH preamble from a set of candidate PRACH preambles based on the determined coverage enhancement category for the UE. In some embodiments, at least some of the candidate PRACH preambles may span a different number of sub-frames.
