Abstract: A base station transmits a first transmission using a first directional beam and determines an equivalent isotropic radiated power (EIRP) relationship between the first transmission and a physical downlink shared channel (PDSCH) for a user equipment (UE). The base station transmits, to the UE, an indication of the EIRP relationship between the first transmission and the PDSCH. Then, the base station transmits the PDSCH to the UE using the second directional beam. The UE uses the indication of the EIRP relationship to receive the PDSCH from the base station over the second directional beam.

The BS may modify the first planned transmit beam, the second planned transmit beam, or both, based on the interference determination.

Abstract: Techniques are provided for reporting, by a device, positioning-related information to a network entity. In an example, the device receives signaling information of the network entity. The signaling information indicates one or more parameters for a report on a reference signal that is transmitted by a base station. The device also receives multiple propagations of the reference signal upon a transmission of the reference signal by the base station. Based on the signaling information, the device generates the report, where the report comprises a power and a time delay per propagation of the reference signal. The device transmits the report to the network entity, where a position of the device is determined by the network entity based on the report.

Abstract: 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.

Abstract: A base station may multiplex a peak suppression information message (PSIM) on a physical downlink shared channel (PDSCH) with data for efficient implementation of PSIMs for peak to average power ratio (PAPR) reduction. A base station may clip peaks from a signal to be transmitted and capture information of the clipped peaks into a PSIM. The base station may then multiplex the PSIM on the PDSCH such that a receiving device (for example, a user equipment (UE)) may receive the signal and reconstruct the signal (for example, PDSCH data) using the PSIM. According to some aspects, each PDSCH symbol may include a PSIM for a previous PDSCH symbol, or the PSIM may be for the current 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.

Abstract: A synchronization signal block (SSB) transmitted by a neighbor base station may interfere with a physical downlink shared channel (PDSCH) transmitted by a serving base station. A user equipment (UE) that receives both the SSB and PDSCH may mitigate the interference to improve an error rate of decoding the PDSCH. The UE may receive a first SSB including a first broadcast channel (BCH) from a second base station other than a serving base station. The UE may decode the first SSB. The UE may determine, based on the first SSB and the first BCH, that the PDSCH scheduled by the serving base station will overlap with a second SSB from the second base station. The UE may estimate a channel of the second SSB based on the decoded first SSB. The UE may remove a reconstructed second SSB from the PDSCH. The UE may decode the PDSCH.

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: 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.

Abstract: Methods, systems, and devices for wireless communications are described. In some examples, a transmitting device (e.g., a base station) may utilize machine learning to modify a signal as conditions of a channel change to reduce a peak to average power (PAPR). For example, a base station may select a type of machine learning. The base station may receive one or more feedback messages related to a condition of a channel and modify a downlink signal based on the selected type of machine learning and the one or more feedback messages. In some cases, the base station may transmit the modified downlink signal to a user equipment (UE) along with information indicating the modified downlink signal and the UE may reconstruct the downlink signal based on the 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.
