  • Patent number: 10826736
    Abstract: Coexistence of OFDM transmissions with different sampling rates, subcarrier spacing, symbol duration, bandwidths, but a constant FFT size, all with the same integer ratio (downclocking or upclocking) N=2, 4, 8 . . . Now called different numerology. Problem of Time alignment due to the presence of alternating long CP and short CPs in a slot. At the slot level the transmissions are aligned, but not at the symbol level. The application proposes to send after the first symbol for N=1 a so-called Time Alignment Period of same duration for each transmission in order allegedly to allow the network nodes to synchronize their timings or clocks without interfering with the transmission or reception of any symbols or CPs of other transmissions.

  • Patent number: 10778476
    Abstract: According to an aspect, there is provided a waveform processing device. The waveform processing device includes circuitry for receiving an input signal including one or more subsequent orthogonal frequency division multiplexing, OFDM, symbol blocks each of which includes a cyclic prefix and an OFDM data block and corresponds to one or more subbands. Further, the waveform processing device includes circuitry for segmenting each OFDM symbol block of the input signal into a set of a pre-defined number of partially overlapping signal blocks of equal length so that non-overlapping samples of the pre-defined number of partially overlapping signal blocks in each set include, in combination, an OFDM data block. Moreover, the waveform processing device includes circuitry for filtering each signal block in each set and for combining the filtered signal blocks in each set using overlap-and-save processing to produce one or more filtered OFDM data blocks for each subband.

  • Publication number: 20200178103
    Abstract: A user equipment (UE) may determine channel state information (CSI) reports with each CSI report being related to a component carrier.

  • Patent number: 10498557
    Abstract: A signal modulated according to zero-tail discrete Fourier transform spread orthogonal frequency division multiplexing (ZT DFT-s-OFDM) is received over a channel. The signal is down-sampled into a first sequence including N samples, N corresponding to the number of used subcarriers. The first Nh samples and the last Nt samples are removed from the first sequence, thereby obtaining a second sequence having a length of N-Nh-Nt. The second sequence is correlated with a reference sequence which has a length N-Nh-Nt, and a frequency response of the channel is estimated over the N used subcarriers based on a result of the correlation.

  • Publication number: 20190363777
    Abstract: Various communication systems may benefit from improved signaling. For example, communication systems may benefit from sending a multi-numerology reference signal that allows a receiving user equipment to perform simultaneous beamforming training, and channel estimation or channel state information acquisition. A method may include receiving at a user equipment a multi-numerology joint reference signal (610). The reference signal may include a reference signal for data channel demodulation or channel state information acquisition, and beamforming training. The method may also include performing simultaneous beamforming training and channel estimation or channel state information acquisition based on the multi-numerology joint reference signal (620).
