Abstract: Techniques discussed herein can facilitate communication of common control messages via multi-beam operation. Embodiments discussed herein can include BSs (Base Stations) configured to transmit scheduling information associated with a common control message via a beamformed DL (Downlink) control channel in each symbol of two or more symbols of a slot, wherein the DL control channel is one of a dedicated physical channel or a NR (New Radio) PDCCH (Physical Downlink Control Channel); and transmit the common control message via a DL data channel based at least in part on the scheduling information.

Abstract: Embodiments of a User Equipment (UE), a generation Node-B (gNB) and methods for communication are generally described herein. The UE may the UE 102 may receive from a gNB, control signaling that indicates: a first pre-coding matrix indicator (PMI) that indicates a first pre-coder for a first sub-band; and a second PMI that indicates a second pre-coder for a second sub-band. The first and second pre-coders may be included in predetermined candidate pre-coders. The UE may encode a physical uplink shared channel (PUSCH) block for transmission. The UE may scale the PUSCH block in the first sub-band by the first pre-coder. The UE may scale the PUSCH block in the second sub-band by the second pre-coder.

Abstract: A receiver processes a data signal and provides an acknowledgement within a turnaround time through use of code block alignment, reduced complexity or increased processing time. In a first embodiment, a radio access network (RAN) node enables encoded information to be segmented into multiple code blocks and maps a group of code blocks to be aligned with orthogonal frequency division multiplexing (OFDM) symbol boundaries such that efficient receiver processing can implement processing pipelining. In a second embodiment, the transmitter can provide more time or reduce the complexity of the packet, such as by repetition of bits of code blocks of the encoded information or by reserving resource elements (REs) such that the receiver has effectively more time (or less complexity) to process the last or last few code blocks of the packet.

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: A user equipment (UE) may assess a radio link quality of a plurality of frames for communication, via the interface to the RF circuitry, with a radio access network (RAN) node. When the radio link quality of a frame, of the plurality of frames, is below an out-of-sync (OOS) threshold, the UE may indicate that the frame is OOS. When the radio link quality of a frame, of the plurality of frames, is above an in-sync (IS) threshold that the frame is IS. Additionally, or alternatively, the UE may process information, received from the RAN node indicating a partial subframe, of a subframe, to be used to transmit uplink control information (UCI) to the RAN node. The UE may also perform UCI mapping for using of the partial subframe to transmit UCI via a physical uplink control channel (PUSCH), and proceed by using the partial subframe to communicate the UCI to the RAN node.

Abstract: A user equipment (UE) or network device gNB can process or generate downlink control information transmissions for new radio (NR) systems or networks based on a compact DCI format. The DCI can include a grouped broadcast message for reduced signaling overhead that comprises random access response (RAR) message, a paging message, a system information block (SIB) message, another message information type, or any combination thereof. The DCI transmission can be determined as comprising paging information based on a direct indication in a physical downlink control channel (PDCCH) only or both in the PDCCH and a physical downlink shared channel (PDSCH) based on a flag field of the DCI transmission. Other configurations can also further reduce signaling overhead additionally or alternatively.

Abstract: Embodiments of a Machine Type Communication User Equipment (MTC UE), Next Generation Node-B (gNB) and methods of communication are generally described herein. The MTC UE may determine a system timing based on reception of a primary synchronization signal (PSS) and a secondary synchronization signal (SSS). The MTC UE may receive, from the gNB, radio resource control (RRC) signaling that indicates one or more parameters of a configurable resynchronization signal (RSS). The RSS may be for resynchronization, by the MTC UE, after the MTC UE awakens from a power save mode. The parameters of the RSS in the RRC signaling may depend on a target coverage of the MTC UE. The MTC UE may determine an updated system timing based on reception of the RSS.

Abstract: Described is an apparatus of a User Equipment (UE) operable to communicate with a fifth-generation Evolved Node-B (gNB) on a wireless network. The apparatus may comprise a first circuitry, a second circuitry, and a third circuitry. The first circuitry may be operable to detect a beam failure event. The second circuitry may be operable to generate a beam failure recovery request for transmission to the gNB, in response to the beam failure event. The third circuitry may be operable to monitor for Physical Downlink Control Channel (PDCCH) in a search space configured by the gNB, subsequent to a transmission of the beam failure recovery request.
