    Abstract: Embodiments of an evolved Node B (eNB) and methods for determining priority values for User Equipment (UE) are generally described herein. A method performed by circuitry of an eNB may include receiving, at the eNB, a usage report from the UE. The usage report may include information indicating a channel usage time and a transmission power of the UE. The method may include determining, using the usage report, a priority value for the UE. The method may include sending the priority value to the UE, wherein the UE is to utilize the priority value to perform distributed scheduling of device-to-device (D2D) communication over a D2D connection with a second UE.

    Abstract: Apparatuses and methods for Non-Orthogonal Multiple Access (NOMA) communication are discussed. An example Evolved NodeB (eNB) includes a memory, a processor, and a transmitter circuit. The processor evaluates an orthogonal multiple access (OMA) metric and a NOMA metric, generates a protocol instruction that indicates an OMA transmission or a NOMA transmission based on the metrics, and determines a first modulation and coding scheme (MCS) for a first UE and a second MCS for a second UE. The transmitter circuit receives the protocol instruction and transmits a first data signal and a first downlink control information (DCI) message associated with the first UE, and a second data signal and a second DCI message associated with the second UE. When the protocol instruction indicates NOMA transmission, the data signals are power multiplexed, the DCI messages indicate the data signals are transmitted via NOMA, and the first DCI message indicates the second MCS.

    Abstract: Narrowband Internet of Things synchronization signals are described that carry offset information. In one example an evolved NodeB (eNB) to performs operations to transmit synchronization signals for time and frequency synchronization between the eNB and user equipments (UEs) for narrowband Internet of things (NB-Iot). The operations include concatenating a plurality of short ZadoffChu (ZC) sequences each having a different root index, the ZC sequences being ordered to indicate an offset for use by a UE, generating an NB-Iot Primary Synchronization Signal (NB-PSS) using the concatenation of short ZadoffChu (ZC) sequences, and transmitting the resulting NB-PSS by the eNB in a periodic manner to the UE, wherein, the offset is identified by the order of the ZC sequences.

    Abstract: Disclosed are apparatuses for communication devices. An apparatus for a communication device includes control circuitry configured to determine a discrete Fourier transform (DFT) of a constant amplitude zero autocorrelation waveform (CAZAC) sequence appended with zeros in the time domain to generate a frequency domain interpolated CAZAC sequence. The control circuitry is also configured to determine an inverse discrete Fourier transform (IDFT) of the frequency domain interpolated CAZAC sequence to generate a demodulation reference signal (DMRS), and cause the DMRS to be transmitted through a cellular data network. An apparatus for a communication device includes control circuitry configured to perform a Fourier transform on a received DMRS to obtain a resulting signal, and use the resulting signal as a reference to demodulate orthogonal frequency-division multiplexing (OFDM) symbols. The control circuitry is also configured to perform a minimum mean squares estimation (MMSE) channel estimation on the resulting signal.

    Abstract: A network device (e.g., an evolved Node B (eNB), user equipment (UE) or the like) can operate to enable scheduling of transmissions within physical resource blocks (PRBs) as a non-orthogonal multiple access (NOMA) zone and as an orthogonal multiple access (OMA) zone to enable multiplexing UEs over a long term evolution (LTE) or next generation (NextGen) 5G based network for uplink transmissions. A first UE of the UEs can be scheduled to generate uplink transmissions from PRBs within the NOMA zone without an explicit grant message based on predefined threshold of a first transmission packet size or a first transmission rate. Another UE can also be scheduled to utilize resources of the NOMA zone or the OMA zone based on the predefined threshold.

    Abstract: Devices and methods of enhancing narrowband communications are generally described. NPSS and NSSS are modulated to include an additional bit that indicates a duplexing scheme, a raster frequency offset (zero or non-zero), an operating mode (in-band or standalone/guard-band) or frame timing used by the eNB. The NPSS modulation uses conjugate ZC sequences multiplied by a cover code for each OFDM symbol. The NMIB may provide additional information related to the operating mode or offset. NSSS cyclic shifts may be used to indicate the offset or TDD/FDD use, as may relative locations of the NPSS and NSSS. The NSSS may use symbol-level modulation and time domain cyclic shifts to indicate the frame timing.
