Patent number: 11424897Abstract: A user equipment (UE) may multiplex peak suppression information message (PSIM) on a physical uplink shared channel (PUSCH) with data for efficient implementation of PSIMs for peak to average power ratio (PAPR) reduction. A UE may clip peaks from a signal to be transmitted and capture information of the clipped peaks into a PSIM. The UE may then multiplex the PSIM on the PUSCH such that a receiving device (for example, a base station) may receive the signal and reconstruct the signal (for example, PUSCH data) using the PSIM. According to some aspects, each PUSCH symbol may include a PSIM for a previous PUSCH symbol (for example, such that causality is preserved if multiplexing PSIM and data for each PUSCH symbol). Various aspects of the techniques described herein may further provide for PSIM positioning in frequency, PSIM modulation, PSIM channel coding, PSIM multiple-input multiple-output (MIMO) configurations, among other examples.Type: GrantFiled: September 24, 2020Date of Patent: August 23, 2022Assignee: QUALCOMM IncorporatedInventors: Ory Eger, Assaf Touboul, Noam Zach, Sharon Levy, Guy Wolf, Shay Landis, Ran Berliner

Publication number: 20220231895Abstract: This disclosure provides methods, devices and systems for reducing PAPR in wireless communications. Some implementations more specifically relate to suppressing the amplitudes of a data signal that exceed a threshold amplitude level. The data signal may represent transmit (TX) data associated with a hybrid automatic repeat request (HARQ) process. In some implementations, a transmitting device may detect one or more peaks associated with the data signal. The transmitting device may reduce the amplitudes of the samples associated with the detected peaks to produce the amplitude-suppressed data signal. The transmitting device may further generate peak suppression information indicating the amplitudes of one or more of the samples associated with the peaks. In response to receiving a NACK message, the transmitting device may transmit, to the receiving device, the peak suppression information, one or more coded bits representing the TX data (associated with the HARQ process), or any combination thereof.Type: ApplicationFiled: January 20, 2021Publication date: July 21, 2022Inventors: Ory Eger, Guy Wolf, Assaf Touboul, Noam Zach, Sharon Levy, Ori Ben Shahar, Ran Berliner

Patent number: 11362694Abstract: Aspects relate to reconstructing a received non-linearly distorted (e.g., clipped) signal. A transmitting device may non-linearly distort a signal to be transmitted (e.g., by clipping peaks of the signal). A receiving device uses a signal reconstruction procedure to reconstruct the original signal. For example, the receiving device may estimate the non-linear distortion (e.g., due to clipped peaks) in the received signal by slicing the received signal, and applying a non-linear distortion to (e.g., clipping) the sliced signal using a threshold that corresponds to a threshold (e.g., a clipping threshold) used by the transmitting device. The receiving device may thereby generate a reconstructed signal based on this estimate of the non-linear distortion.Type: GrantFiled: May 5, 2021Date of Patent: June 14, 2022Assignee: QUALCOMM IncorporatedInventors: Yaron Laufer, Gideon Kutz, Elad Meir, Ory Eger, Assaf Touboul

Publication number: 20210385116Abstract: Methods, systems, and devices for wireless communications are described. A transmitting device may reduce a channel overhead of a peak suppression information message (PSIM) by reducing amplitude signaling of clipped peaks of a data signal. To avoid including amplitude information for each clipped peak of a time-domain data signal in a PSIM, the transmitting device may subtract a constant amplitude offset from each peak above a clipping threshold in the time-domain data signal. The transmitting device may indicate the amplitude offset in the PSIM, and a receiving device may reconstruct the data message based on the amplitude offset. In some examples, the transmitting device may indicate a peak to average power ratio (PAPR) in the PSIM, such as a PAPR of a maximum peak in the data signal. Based on the indicated PAPR, the receiving device may perform a calculation to determine the amplitude offset for reconstructing the data message.Type: ApplicationFiled: May 28, 2021Publication date: December 9, 2021Inventors: Noam Zach, Guy Wolf, Ory Eger, Sharon Levy, Assaf Touboul
