  • Patent number: 10999117
    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.

  • Patent number: 10873969
    Abstract: Technology for a user equipment (UE) operable for beam management is disclosed. The UE can be configured to decode, at the UE, a transmission configuration indicator (TCI), wherein the TCI is configured for a control channel and a data channel for all bandwidth parts (BWPs) of the UE or all component carriers (CCs) of the UE.

  • Publication number: 20200214083
    Abstract: An apparatus of user equipment (UE) includes processing circuitry coupled to a memory, where to configure the UE for DMRS processing in an NR network, the processing circuitry is to decode higher layer signaling, the higher layer signaling to indicate whether transform precoding is enabled and to indicate a modulation scheme for a physical uplink shared channel (PUSCH) if transform precoding is enabled. A set of low Peak-to-Average-Power-Ratio (PAPR) base sequences of length-6 is generated. A reference signal sequence is generated as a demodulation reference signal (DMRS) using the set of low-PAPR base sequences, based on the modulation scheme if transform precoding is enabled by the higher layer signaling, the modulation scheme being a ?/2-binary phase-shift keying (BPSK) modulation scheme. Mapping of the DMRS to physical resources for transmission using the PUSCH is performed.

  • Publication number: 20200146107
    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 in 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.
