Abstract: The disclosure describes mechanisms for reliability enhancement on control channel and data channel and mechanisms in URLLC. An apparatus of a RAN node for URLLC includes baseband circuitry to configure at least one DCI for scheduling transmission of at least one PDSCH content having same information. For each DCI, the baseband circuitry determines a CORESET for transmitting the DCI. The disclosure further describes mechanisms for the support of low latency transmission in URLLC. To improve peak data rate and spectrum efficiency in FDD system, the RAN node configures a DCI for scheduling data transmission using blank resources of a self-contained slot structure. Further, CBG-based transmission with separate HARQ-ACK feedback is provided to configure a DCI for scheduling data transmission of a TB and to divide the TB into multiple CBGs, and to configure uplink control data to carry separate HARQ feedback for the CBGs.

Abstract: Embodiments of dynamic multiplexing are described, including the transmission of preemption indication (PI) to indicate preemption of time-frequency resources. In some embodiments, a next Generation NodeB (gNB) is configured to transmit PIs in signaling to preempt an enhanced Mobile Broadband (eMBB) communications transmission with an ultra-reliable and low latency communications (URLCC) transmission. In some embodiments, a user equipment (UE) is configured to monitor a region of time-frequency resources, within a bandwidth part (BWP), for a PI. The PI indicates to the UE a portion of time-frequency resources that omit transmissions intended for the UE. In some embodiments, the gNB transmits the PI to the UE within preemption indication downlink control information (PI-DCI) in a physical downlink control channel (PDCCH) in a control resource set (CORESET). In some embodiments, the BWP is defined according to a frequency domain location, a bandwidth, and a subcarrier spacing for a given numerology.

Abstract: Technologies described herein provide mechanisms and formats to accomplish the beam switching. In one implementation, least one frame structure for both uplink (UL) and downlink (DL) beam switching is provided. The UL beam switching and refinement may rely on 5G Physical Random Access Channel (xPRACH) or 5G Sounding Reference Signal (xSRS). The DL beam switching and refinement may be done based on a beam refinement reference signal (BRRS). In some embodiments, to accomplish the both UL and DL beam switching and refinement in one subframe, the BRRS and xPRACH or xSRS may be located in one subframe.

Abstract: A network device (e.g., a user equipment (UE), or a new radio NB (gNB)) can process or generate a configuration of physical downlink control channel (PDCCH) monitoring in different search spaces sets independently from one another in order to manage different services optimally. A processor of the network device can be configured to receive physical downlink control channel (PDCCH) candidates of a PDCCH in a slot for channel estimation across search spaces of the slot. Different priorities can be determined among the PDCCH candidates in the slot based on a priority rule. Then a number of PDCCH candidates can be skipped/dropped from monitoring based on the different priorities of the PDCCH candidates to ensure that a threshold level of blind decoding operations across a plurality of slots of the PDCCH is being satisfied. The UE can monitor a portion of the PDCCH candidates while concurrently skipping another.

Abstract: Technology for a Next Generation NodeB (gNB) operable to encode downlink control information (DCI) for transmission to a user equipment (UE) is disclosed. The gNB can identify DCI for transmission from the gNB. The gNB can determine that a size of the DCI exceeds a defined threshold. The gNB can divide the DCI into one or more DCI segments. Each DCI segment can include header information to enable the one or more DCI segments to be assembled at the UE. The gNB can encode the one or more DCI segments of the DCI for transmission from the gNB to the UE.

Abstract: Technology for a user equipment (UE) configured for communication of sounding reference signal (SRS) resources is disclosed. The UE can decode a radio resource control (RRC) signal indicating an SRS to transmit with a physical uplink control channel (PUCCH), wherein the PUCCH and the SRS are quasi co located (QCLed) based on a spatial received parameter. The UE can encode an SRS for transmission using the spatial received parameter. The UE can encode uplink control information (UCI) for transmission in the PUCCH using the spatial received parameter. The UE can have a memory interface configured to send to a memory the spatial received parameter.

Abstract: New radio (NR) Uplink (UL) transmissions in an NR physical UL channel can be configured for a user equipment (UE) to communicate with a base station (e.g., gNB). The structures and mechanisms for configured these communications different from long term evolution (LTE) in NR specifications. A UE can generate a UL transmission with symbols on the NR physical channel including demodulation-reference signal (DM-RS) symbols and uplink control information (UCI) symbols. The UL transmissions comprise a DM-RS symbol located at each first symbol with variable lengths. The UE generates the UL transmission as an NR physical UL channel with about a 50% DM-RS overhead with a same or more DM-RS symbols than UCI symbols in a sequential pattern (e.g., an alternating pattern). The UE further maps HARQ-ACK feedback on a PUSCH based a frequency first operation that initiates following the DM-RS symbol located at the first symbol.
