Abstract: Methods, systems, and devices for wireless communications are described. An interfering base station may transmit to a neighboring base station a configuration to measure beam resources for a plurality of PAPR reduction beams. The neighboring base station may forward this measurement configuration to an associated UE. The UE may then take measurements of the interfering base station's PAPR reduction beams in accordance with the configuration and transmit the report to its serving base station. The neighboring base station may then compile a headroom report and transmit the headroom report to the interfering base station. The interfering base station may then adjust its PAPR reduction beams based on the headroom report.

Abstract: A direction-controlled PAPR reduction is provided in which a base station transmits a PAPR reduction signal using a subset of antenna beams selected from a null space plurality of antenna beams. The subset of antenna beams is selected such that the PAPR reduction signal is not directed having a relatively-high path gain to a UE and/or so that the PAPR reduction signal power is concentrated in directions that have a relatively-lo path gain to the UE.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment may transmit a request, for an uplink transmission or a downlink transmission, for amplitude modulated phase tracking reference signals; and communicate the uplink transmission or the downlink transmission based at least in part on the request. Numerous other aspects are provided.

Abstract: Disclosed are techniques for wireless communication. In an aspect, a base station receives one or more signals indicative of a downlink compensation capability (e.g., an in-band capability to compensate for non-linear distortion, or an out-of-band capability to compensate for other FDM'd signal(s) to other UE(s), etc.) of at least one UE. The base station determines a set of downlink transmission requirements based on the downlink compensation capability of the at least one UE, and transmits data to the at least one UE in accordance with the set of downlink transmission requirements.

Abstract: Methods, systems, and devices for wireless communications are described. A transmitting device (e.g., a user equipment (UE) or base station) may reduce a peak to average power ratio (PAPR) by clipping signals transmitted to a receiving device according to a clipping level. The receiving device may receive, from the transmitting device, an indication of the clipping level associated with a reference signal. The receiving device may receive the reference signal and identify distortions based on the clipping level. The receiving device may iteratively reconstruct peaks of the clipped reference signal until the receiving device is able to obtain accurate pilot symbols for use in channel estimation. The techniques described herein may enable receiving devices to improve efficiency and reliability of communications by improving channel estimation, which may increase the probability of successfully decoding transmitted information.

Abstract: Techniques for wireless communications are described. A communication device may support processing digital post distortion using additional references symbols. For example, the communication device may precode a signal including at least two reference symbols for a single-layer transmission using at least two antenna ports. At least one reference symbol of the at least two reference symbols is associated with at least one data symbol of a data stream. The communication device may estimate, based on the at least two reference symbols, a nonlinearity model of at least two power amplifiers associated with the single-layer transmission, and determine an estimate of a nonlinearity factor of the precoded signal based on the estimated nonlinearity model. As a result, the communication device may eliminate or reduce the nonlinear factor of the precoded signal based on the estimated nonlinearity model of the at least two power amplifiers and the estimated channel impulse response.

Abstract: In embodiments of systems and methods for protecting wireless communications a base station and the wireless device, a base station receive from a wireless device channel feedback from a wireless device regarding a communication beam between the base station and the wireless device, generate a barrage signal precoder based on the received channel feedback regarding the communication beam, and transmit a barrage signal using the barrage signal precoder on a second beam that is different from the communication beam.

Abstract: 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.

Abstract: A transmitting device may reduce a peak to average power ratio (PAPR) ratio by clipping samples that have an amplitude exceeding a threshold. For a downlink transmission, the transmitting device may transmit an incremental peak suppression information message (PSIM) to multiple user equipments (UEs). A UE may receive downlink control information (DCI) indicating a data and a modulation and coding scheme (MCS) for the UE, and at least a first incremental PSIM. The UE may decode at least the first incremental PSIM that is applicable to a MCS lower than or equal to the MCS for the UE. The UE may determine whether to decode one or more subsequent incremental PSIMs based on the MCS for the UE. The UE may apply peak information from the incremental PSIMs to the data channel. The UE may decode the data channel based on the MCS for the UE.
