  • Patent number: 10530625
    Abstract: Methods, systems, and devices for wireless communication are described. A user equipment (UE) may be configured with a transmission stream processor used to maintain a lower peak-to-average power ratio (PAPR) for uplink transmissions. In some cases, a UE may map modulated symbols of different signals (or waveforms) to interleaved subsets of frequency resources, and this form of frequency division multiplexing (FDM) may increase the PAPR of an uplink transmission. To reduce the PAPR of uplink transmissions, a transmission stream processor at the UE may support techniques for phase ramping modulated symbols in the time domain prior to mapping the symbols to the frequency resources. These techniques may help to ensure that the signals to be included in an uplink transmission are aligned in such a way that the PAPR of the uplink transmission is reduced.

  • Patent number: 10530561
    Abstract: Apparatus and associated methods relate to using a high learning rate to speed up the training of a receiver and switching from a high learning rate to a low learning rate for fine tuning based on exponentially weighted moving average convergence. In an illustrative example, a selection circuit may switch the high learning rate to the low learning rate based on a comparison of a moving average difference en to a predetermined stability criteria T1 of the receiver. The moving average difference en may include an exponentially weighted moving average of a difference between two consecutive exponentially weighted moving averages of an operation parameter un of the signal communication channel. By using this method, the training time for the receiver may be advantageously reduced.

  • Patent number: 10531090
    Abstract: Aspects of the disclosure provide method and apparatus for video encoding/decoding. In some examples, an apparatus for video decoding includes receiving circuitry and processing circuitry. The processing circuitry decodes prediction information for a block in a current picture that is a part of a coded video bitstream. The prediction information is indicative of an inter prediction mode. In response to the inter prediction mode, the processing circuitry constructs a candidate list of candidate motion vector predictors in a ranking order that are sorted based on statistics of motion information in a spatial neighboring region of the block. The processing circuitry then determines, a motion vector predictor from the candidate list following the ranking order, and reconstructs samples of the block according to motion information associated with the determined motion vector predictor.
