Abstract: A user equipment (UE) can include processing circuitry coupled to memory. To configure the UE for New Radio (NR) communications above a 52.6 GHz carrier frequency, the processing circuitry is to decode radio resource control (RRC) signaling to obtain a cyclic shift value in time domain. The cyclic shift value is associated with a demodulation reference signal (DM-RS) antenna port (AP) of a plurality of available DM-RS APs. A single carrier based waveform DM-RS sequence corresponding to the DM-RS AP is generated using a base sequence and the cyclic shift value. The single carrier based waveform DM-RS sequence is encoded with uplink data for transmission to a base station using a physical uplink shared channel (PUSCH) using a carrier above the 52.6 GHz carrier frequency.

Abstract: Systems, methods, and circuitries are provided for adjusting contention window size (CWS). An example method includes selecting a downlink (DL) burst transmitted by the gNB for use in determining the CWS and adjusting the CWS based on Hybrid Automatic Repeat Request (HARQ) feedback received with respect to the selected DL burst.

Abstract: Systems and methods of reducing power consumption associated with paging or cDRX mode are described. A wake-up receiver (WUR) wakes up from an idle mode or cDRX state. Whether a wake-up signal (WUS) has been received by the WUR is determined. The WUS is a low-complexity signal that is less complicated than a PDCCH or PDSCH and is repeated multiple times at resource elements as indicated in a configuration from an eNB. If received, a baseband transceiver wakes up for reception of a PDCCH for the UE in a PO when the UE is in the idle mode or a PDSCH for the UE when the UE is in the cDRX state.

Abstract: Apparatuses, systems, and methods for performing contention window size updates for code block group based retransmission configurations in a wireless communication system. A code block group based wireless communication may be performed in unlicensed spectrum. A reference burst of the code block group based wireless communication may be identified. One or more of a number of acknowledgements or a number of negative acknowledgements associated with the reference burst may be identified. A contention window size adjustment may be determined based at least in part on one or more of the number of acknowledgements or the number of negative acknowledgements associated with the reference burst.

Abstract: Embodiments of efeMTC synchronization signals for enhanced cell search and enhanced system information acquisition are described. In some embodiments, an apparatus of a base station (BS) is configured to generate a length-x sequence for an efeMTC synchronization signal, the length-x sequence configured for repetition in frequency domain within 6 physical resource blocks (PRB). In some embodiments, to generate the length-x sequence, the BS may be configured to select any one index of the set of root indices {1, 2, 63}, excluding the root indices 25, 29 and 34, to correspond to a different physical-layer cell identity (PCID). In some embodiments, the BS may be configured to encode RRC signaling to include a System Information Block (SIB) comprising configuration information for transmission of the efeMTC synchronization signal, and transmit the length-x sequence as the efeMTC synchronization signal in frequency resources according to the SIB.

Abstract: Systems, apparatuses, methods, and computer-readable media are provided for a user equipment (UE) device that includes one or more processors configured to determine, based on a DL signal in an LTE-TDD radio frame, that an eNB has assessed, based on a Cat-2 listen before talk (LBT) procedure, that a radio frame is valid; and in response to determining that the radio frame is valid, transmitting a UL burst within a predetermined period of time after a DL burst in the radio frame.

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 (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-MF-BR).

Abstract: A network device (e.g., a user equipment (UE), a new radio NB (gNB), or other network component) can process or generate a dynamic indication that indicates a transmission bandwidth based on a wideband bandwidth. One or more downlink (DL) signals can be provided with the indication of the transmission bandwidth that enables a tuning of communications within the wideband bandwidth based on the indication for new radio (NR) communications in heterogeneous network domains ranging from Enhanced Mobile Broadband (eMBB) to massive Machine-Type Communications (mMTC) and Ultra-Reliable Low-Latency Communications (URLLC) or the like.
