  • Patent number: 11956006
    Abstract: This disclosure provides systems, methods and apparatus, including computer programs encoded on computer storage media, for performing wireless communication using digital post distortion, for example, with a large antenna array where the number of transmit antennas may be greater than a number of spatial streams. A transmitting device and a receiving device determine a perturbed precoding matrix based on a precoding perturbation rule. The transmitting device precodes a signal using the perturbed precoding matrix and transmits via the number of antennas greater than the number of spatial streams. The receiving device receives the signal and subtracts non-linearities from the received signal based on a channel estimation using the perturbed precoding matrix over one or more iterations.

  • Publication number: 20240039775
    Abstract: This disclosure provides systems, methods and apparatus, including computer programs encoded on computer storage media, for non-linearity estimation techniques for digital post distortion (DPoD) in a wireless system. In some aspects, a first wireless device may estimate a power amplifier (PA) non-linearity associated with a second wireless device using select signaling from the second wireless device. For example, the first wireless device may use a received signal to estimate the PA non-linearity if a dynamic power range associated with the signal triggers the estimation of the PA non-linearity (such as if the dynamic power range associated with the signal satisfies, or is expected to satisfy, a threshold dynamic power range). If the dynamic power range of the signal triggers the estimation of the PA non-linearity, the first wireless device may introduce DPoD to signaling received from the second wireless device in accordance with the estimation of the PA non-linearity.

  • Patent number: 11888670
    Abstract: Methods, systems, and devices for wireless communications are described. Techniques provide for reliable signal processing and amplification of downlink signals. A network entity may apply a digital pre-distortion (DPD) process to a signal for transmission to a user equipment (UE) and may apply a crest factor reduction (CFR) process to the output of the DPD process. The output of the CFR process may be amplified by a power amplifier and transmitted via a downlink transmission to the UE. The CFR process limits the peak power of the signal provided to the power amplifier (e.g., to a configured level), thereby reducing the peak to average power ratio (PAPR) of the signal provided to the power amplifier. The DPD process may compensate for non-linearities of the power amplifier. A training procedure for the DPD process may account for the CFR process applied after the DPD process.

  • Publication number: 20230262702
    Abstract: Methods, systems, and devices for wireless communications are described. In some examples, when a high subcarrier spacing (SCS) is used for sidelink communications, the user equipments (UEs) may use a modified sidelink slot structure for the sidelink communications. In one example, the slot structure may include at least two automatic gain control (AGC) symbols with at least one sidelink control channel symbol between the two AGC symbols. The UE may perform an AGC procedure during the two AGC symbols and the sidelink control channel symbol. In some examples, the slot structure may include bundled slots to minimize per slot overhead associated with AGC symbols and sidelink control channel symbols. For example, at a high SCS, the slot structure may include a first slot including multiple AGC symbols, Subsequent bundled slots may not include AGC symbols and/or sidelink control channel symbols.
