Abstract: A network device such as an evolved NodeB (eNB) or next generation NodeB (gNB) can configure a set of user equipment (UE) for cell reference signal (CRS) muting in order to provide better channel quality and power efficiency in communications. Where an eNB mutes CRS transmissions that are not needed by any UE, an improvement in downlink throughput and reduce connection drop rate can be generated. A CRS muting capability can be determined based on a user equipment (UE) capability information. According to the CRS muting capability of a UE, CRS muting can be generated in a physical channel outside of a narrow band (NB) or a wide band (WB) plus/minus X physical resource blocks (PRBs), wherein X is a non-negative integer, based on the CRS muting capability.

Abstract: transmissions outside a transmission opportunity (TxOP) is disclosed. The UE can process an uplink (UL) opportunity received from an eNodeB during a defined transmission opportunity (TxOP). The UL opportunity can schedule UL information to be transmitted from the UE on one or more UL subframes that are outside the defined TxOP. The UE can initiate a listen-before-talk (LBT) procedure to be performed before the UL information is transmitted from the UE on the one or more UL subframes that are outside the defined TxOP. The UE can process the UL information for transmission to the eNodeB on the one or more UL subframes located outside the defined TxOP.

Abstract: Described is an apparatus of a User Equipment (UE). The apparatus may comprise a first circuitry and a second circuitry. The first circuitry may be operable to establish that Downlink (DL) transmissions from a second Evolved Node-B (eNB) will interfere in one or more subframes with Uplink (UL) transmissions from the UE to a first eNB. The second circuitry may be operable to modulate a UL transmission power based upon the established interference condition.

Abstract: Systems, methods, and apparatuses can provide or obtain scheduling information for a system information block type1-bandwidth reduced (SIB1-BR) without obtaining a master information block during handover. A user equipment (UE) can identify SIB1-BR scheduling information in a radio resource control connection (RRC) reconfiguration message. The UE can determine scheduling of an SIB1-BR for a target cell based on the RRC reconfiguration message, and process the SIB1-BR received from the target cell during the determined scheduling.

Abstract: Systems and methods of providing a NPRACH preamble in a multefire system are described. A UE configured for multefire NB-IoT or eMTC operation receives, from an eNB, access information that includes a SIB on a narrowband channel of an unlicensed band. Based on the access information, the UE transmits a NPRACH preamble in two or six contiguous uplink subframes. The NPRACH preamble is transmitted in two or six contiguous subframes. When two subframes are used, four symbol groups each having a 266.7 μs CP and two symbols are transmitted without a gap therebetween. When six subframes are used, four symbol groups each having a 266.7 μs CP and five symbols are transmitted without a gap therebetween.

Abstract: Technology for a Next Generation NodeB (gNB) operable to communicate over an anchor channel for Unlicensed Internet of Things (U-IoT) is disclosed. The gNB can encode control information for transmission on two discovery reference signal (DRS) subframes to a user equipment 5 (UE). The control information can be transmitted on an anchor channel having a set frequency for U-IoT in an adaptive frequency hopping system. The control information can include: a primary synchronization signal (PSS), a secondary synchronization signal (SSS), a physical broadcast channel (PBCH) transmission, and a system information block for MulteFire bandwidth reduced (SIB-MF10 BR).

Abstract: Systems and methods are described for wake-up signaling of user equipment (UE). The systems and methods can include at least generating, by the BS, a wake up signal (WUS), wherein the WUS includes a length-131 Zadoff-Chu (ZC) sequence and a Gold sequence for radio equipment-level (RE-level) scrambling, and transmitting, by the BS, the WUS to a user equipment (UE) in a paging group associated with the WUS.

Abstract: Systems, devices, and techniques for user equipment (UE) power control are described. A described technique includes receiving, by a UE, a discontinuous receiving (DRX) configuration from a base station; monitoring, by the UE on a physical downlink control channel (PDCCH), for downlink control information (DCI) messages outside of a DRX active time, the DCI messages being of a predetermined format that is configured to provide wake-up signaling; receiving, by the UE, a DCI message outside of the DRX active time, the DCI message being of the predetermined format; and determining, by the UE, whether to wake-up based on the received DCI message.

Abstract: Embodiments are provided for resource monitoring and power saving in a user equipment (UE) operating according to a discontinuous reception (DRX) in new radio (NR) wireless communication system. The UE, operating in the DRX mode, monitors for a wake up occasion in control signal prior to the DRX ON time. If the wake occasion is detected, then the EFE monitors for a channel state information (CSI) resource signal (RS) prior to the DRX ON time. If no wake up occasion is detected, then at least a portion of the UE remains in a sleep mode prior to DRX ON time.
