    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: Technology for a base station operable to encode guard interval (GI) discrete Fourier transform (DFT) spread orthogonal frequency-division multiplexing (OFDM) (GI-DFT-s-OFDM) data symbols for transmission to a user equipment (UE) is disclosed. The base station can identify GI-DFT-s-O 5 FDM data symbols for transmission to the UE. The base station can encode the GI-DFT-s-OFDM data symbols for transmission to the UE in a subframe. The subframe can be in accordance with a flexible subframe structure that begins with a demodulation reference signal (DMRS) sequence followed by a GI sequence in a first symbol of the subframe. The subframe can further comprise one or 10 more subsequent symbols in the subframe that each include a GI-DFT-s-OFDM data symbol followed by a GI sequence.

    Abstract: Embodiments include apparatuses, methods, and systems that may be used in a UE in a mobile communication network to communicate with a gNB. An apparatus may include a memory and processing circuitry coupled with the memory. The processing circuitry may cause coarse time and frequency synchronization information, obtained from primary and secondary synchronization signals (PSS/SSS), to be stored in the memory. Based on the coarse time and frequency synchronization information, the processing circuitry may decode a physical broadcast channel to obtain a first system information, and may acquire a second system information based on the first system information. Based on the first and second system information, the processing circuitry may cause a transmission of a PRACH, to trigger a transmission of a TRS by the gNB. Other embodiments may also be described and claimed.

    Abstract: Devices and methods of on-demand system information block (SIB) transmission are generally described. A user equipment (UE) can be configured to determine a beam index during a beam sweeping procedure, based on a signal quality metric associated with a received synchronization signal. The UE can encode for directional transmission based on the beam index, a random access procedure (RACH) preamble sequence. The RACH preamble sequence can include a system information request. The UE can decode system information configuration received in response to the system information request. The UE can initiate a RACH process using another RACH preamble sequence, based on the received system information configuration. The encoded RACH preamble sequence with the system information request can be transmitted multiple times using the preferred beam index.
