    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 using xSS are generally disclosed. A UE receives an xPSS with (Nrep) symbols each with a subcarrier spacing of K×a PSS subcarrier spacing and a duration of a PSS symbol/K. PSD subcarriers surround the xPSS and the ZC sequence is punctured to avoid transmission on a DC subcarrier. Guard subcarriers separate the xPSS and PSD when the ZC sequence is less than the occupied BW of the xPSS and at least one element in the ZC sequence is punctured for xPSS symbol generation otherwise. One or more xSSSs and xS-SCHs may follow the xPSS. The xSS may be omnidirectional, each having a same xPSS and different xSSS or xS-SCH or a different xPSS and same xSSS or xS-SCH or beamformed, each having different xPSSs and xSSSs or xS-SCHs or a same xPSS and different xSSS or xS-SCH.

    Abstract: Technology for efficient distributed scheduling is provided using tentative grants. A UE can receive a transmission request from a Tx UE, and from additional Tx UEs. Each Tx request can include a priority level of the transmitter UE sending the transmission request, to form a priority list. An incompatible list can be formed based on a signal to interference ratio of each transmitter with the UE. A grant message and the incompatible list can be transmitted for n−1 iterations from selected UEs based on the priority list and incompatible list. A tentative bandwidth grant can then be transmitted at an nth iteration to tentatively allow the transmitter UE to send a D2D communication to the UE in the bandwidth grant.

    Abstract: Systems and methods for enhancing spectral efficiency are disclosed herein. User equipment (UE) may be configured to communicatively couple to an Evolved Universal Terrestrial Radio Access Network (E-UTRAN) Node B (eNB). The UE may be configured to cancel interference from an interfering eNB. The interfering eNB may provide transmission parameters to the UE. The interfering eNB may transmit a compact message indicative of the transmission parameters to the UE. The compact message may be a broadcast message. Some transmission parameters may be sent to the UE using higher layer signaling. The UE may be able to use the transmission parameters to cancel interference from the interfering eNB. In some embodiments, the interfering and/or serving eNB may indicate to the UE whether the transmission parameters are being broadcast so the UE does not search for them unnecessarily.

    Abstract: Devices and methods of using xSS are generally disclosed. A UE receives an xPSS with (Nrep) symbols each with a subcarrier spacing of K x a PSS subcarrier spacing and a duration of a PSS symbol/K.

Guard subcarriers separate the xPSS and PSD when the ZC sequence is less than the occupied BW of the xPSS and at least one element in the ZC sequence is punctured for xPSS symbol generation otherwise.

    IPC: H04L27/26

    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.
