  • Patent number: 11018909
    Abstract: A receiver receives communications over a communication channel, which may distort an incoming communication signal. In order to counter this distortion, the frequency response of the receiver is manipulated by adjusting several frequency response parameters. Each frequency response parameter controls at least a portion of the frequency response of the receiver. The optimal values for the frequency response parameters are determined by modifying an initial set of values for the frequency response parameters through one or more of stochastic hill climbing operations until a performance metric associated with the receiver reaches a local maximum. The modified values are displaced through one or more mutation operations. The stochastic hill climbing operations may subsequently be performed on the mutated values to generate the final values for the frequency response parameters.

  • Patent number: 11005597
    Abstract: A wireless transmit receive unit (WTRU) may receive a Physical Downlink Control Channel (PDCCH) transmission and perform early termination on the PDCCH transmission. Transmissions that are not intended for the WTRU may be terminated. The WTRU may perform a first decode of the PDCCH transmission based on a first scrambling sequence. The first scrambling sequence may be generated using a Gold sequence, which may be initialized based on a WTRU identifier. If the first decode is not successful, the WTRU may determine that the PDCCH transmission is not intended for the WTRU. The WTRU may perform an assistance bit added (ABA) polar decode of the PDCCH transmission based on a second scrambling sequence (e.g., a cell radio network temporary ID (C-RNTI)). The WTRU may perform a CRC on the output of the ABA polar decode to obtain downlink control information (DCI).

  • Patent number: 10985961
    Abstract: Disclosed techniques for improving computational efficiency can be applied to synthesis and analysis in digital signal processing. A base discrete-time Orthogonal Frequency Division Multiplexing (OFDM) signal is generated by performing an inverse discrete Fourier transform (IDFT) on a set of data symbols. The set of data symbols is multiplied with a sparse update weight matrix to produce an update signal, and an IDFT is performed on the update signal to generate a discrete-time update signal. The discrete-time update signal is summed with the base discrete-time OFDM signal to produce an updated discrete-time OFDM signal.

  • Patent number: 10973020
    Abstract: A signal scrambling method and apparatus, and a signal descrambling method and apparatus are disclosed. In the signal scrambling method, a communications apparatus scrambles a signal by using a scrambling sequence, and sends the scrambled signal. In the signal descrambling method, a communications apparatus receives a signal, and descrambles the signal by using a scrambling sequence. An initial value of the scrambling sequence is determined based on a time unit number corresponding to a frame structure parameter used for transmitting the signal, so that different scrambling sequences can be used to scramble signals that are transmitted by using different frame structure parameters. Therefore, interference randomization can be implemented for signal scrambling, and this can be applicable to various application scenarios in 5G NR to improve performance.
