Abstract: Systems and methods of providing timing information for initial access in an unlicensed band are described. A UE monitors a new radio discovery signal (NRDS-U) window in an unlicensed band for a DRS transmission that is constrained to be transmitted within the NRDS-U window. The UE determines initial access information, including an offset that indicates when the DRS transmission occurs within the NRDS-U window, and engages in initial access dependent on the offset. The offset is from a radio frame or half radio frame boundary or the start of the NRDS-U window. The offset is indicated in three least/most significant bits an SSB index or from an sl-offset field in a MIB of the SSB. When the base station uses a DFS channel, the base station transmits a periodic signal to emulate a radar signal.

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: 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 process a first Downlink Control Information (DCI) format 0A transmission indicating a Grant-less Uplink (GUL) activation. The first circuitry may also be operable to process a second DCI format 0A transmission indicating a GUL release. The second circuitry may be operable to generate one or more Uplink (UL) transmissions for an unlicensed spectrum of the wireless network after the GUL activation and before the GUL release.

Abstract: In embodiments, a base station may be able to identify whether a user equipment (UE) is to operate within the cellular network in accordance with a wideband (WB) protocol or a narrowband (NB) protocol. Based on this identification, the base station may further be able to identify a number of resource blocks (RBs) that include subcarriers occupied by enhanced narrowband control channel elements (eNCCEs). Finally, the base station may be able to transmit the eNCCEs on the subcarriers. Other embodiments may be described and/or claimed.

Abstract: A network device (e.g., a user equipment (UE), a new radio NB (gNB), or other network component) can process or generate a Physical Uplink Shared Channel (PUSCH) based on a configured grant that enables different configurations with multiple starting symbol occasions for the configured grants in new radio (NR) unlicensed communications. The PUSCH can be type A or as type B based on the configured grant. A number M of demodulation reference signals (DMRSs) and a number N of starting symbol occasions in a slot can be configured according to the configured grant, wherein M and N comprise an integer greater than zero, respectively.

Abstract: The disclosure describes design of a synchronization signal (SS) block for an unlicensed carrier, and listen before talk (LBT) strategies for initial access. An apparatus of a radio access network (RAN) is disclosed. The apparatus includes baseband circuitry that includes one or more processors and a radio frequency (RF) interface. The one or more processors are to generate, for user equipment (UE) operating on a licensed assisted access (LAA) secondary cell (SCell), a data sequence associated with an SS block. The SS block includes a primary synchronization signal (PSS) and a secondary synchronization signal (SSS), but does not include a physical broadcast channel (PBCH). The RF interface is to receive the data sequence from the one or more processors.

Abstract: Systems and methods of early termination of uplink data transmissions for a UE are described. The UE transmits capacity information that indicates that the UE supports use of an ETS. The ETS indicates successful reception by the eNB of the uplink data prior to an end of a scheduled transmission period to transmit repeated instances of the data. The UE receives a schedule for repeated transmissions of the data that is based on a coverage level of the UE, and then transmits sets of one or more repetitions. After the transmission, the UE monitors a predetermined resource whether the ETS is present or whether the ETS indicates an ACK. If the ETS indicates successful reception, the UE terminates transmission of the remaining repetitions of the data and enters a sleep mode or transmits other uplink data.

Abstract: Technology for a user equipment (UE) operable to perform reference signal received power (RSRP) measurements in an enhanced Machine Type Communication in an unlicensed spectrum (eMTC-U) system is disclosed. The UE can decode a presence-detection reference signal (PD-RS) received on one or more data channels from a Next Generation NodeB (gNB) in the eMTC-U system. The UE can perform an RSRP measurement using the PD-RS received on the one or more data channels from the gNB. The RSRP measurement can be performed over a selected measurement period and a selected measurement frequency bandwidth.
