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: Methods, systems, and devices for wireless communications are described. A first wireless device may communicate, with a second wireless device, a first set of messages of a first message type that are acknowledged according to an acknowledgement procedure. The first wireless device, the second wireless device, or both may select a first subset of messages of the first plurality of messages and a first subset of bits from each message of the first subset of messages based on the first set of messages being acknowledged and according to a sampling configuration common to both the first wireless device and the second wireless device. The first wireless device, the second wireless device, or both may generate a key using bit values of the first subset of bits from each message of the first subset of messages, encoding a message using the key, and communicate the encoded message.

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. In some implementations, a transmitting device may detect one or more peaks associated with a data signal to be transmitted to a receiving device. A peak may be any sample of a data signal having an amplitude that exceeds a threshold amplitude level. The transmitting device generates peak suppression information indicating the amplitude, a phase and a position of each of the samples associated with the detected peaks. The transmitting device adjusts the data signal by reducing the amplitudes associated with the detected peaks and transmits the adjusted data signal, with the peak suppression information, to the receiving device. In some implementations, the transmitting device may compress the peak suppression information to reduce the overhead of the transmission.

Abstract: In a wireless communication system, a peak to average power ratio (PAPR) may affect the efficiency of a power amplifier. To reduce a PAPR, a transmitting device may utilize a PAPR reduction precoding that changes a received signal without performance impact so the overall transmit PAPR is reduced. The transmitting device constructs a frequency domain (FD) response to the PAPR reduction precoding, estimates a channel to one or more receiving devices, and applies the PAPR reduction precoding to the estimated channel. The transmitting device constructs a multiple input multiple output (MIMO) precoding matrix considering the FD response of the PAPR reduction precoding and applies the MIMO precoding matrix and the PAPR reduction precoding to an FD signal. A receiving device applies the FD response conjugated to a received FD signal from the transmitting device and processes at least a received reference signal based on the PAPR reduction precoder.

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: 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.

Abstract: Methods, systems, and devices for wireless communications are described. A receiving device may receive a channel estimation reference signal (CHEST-RS) transmitted over a bandwidth, the CHEST-RS associated with a power amplifier (PA) configuration of a transmitting device. The receiving device may determine a channel estimation measurement associated with the PA configuration based at least in part on the CHEST-RS. The receiving device may receive a non-linear estimation reference signal (NLEST-RS) transmitted over a subset bandwidth of the bandwidth, the NLEST-RS associated with the PA configuration. The receiving device may determine a non-linear estimation measurement associated with the PA configuration based at least in part on the NLEST-RS and the CHEST-RS, the non-linear estimation measurement identifying a non-linear response of the PA configuration. The receiving device may communicate with the transmitting device based at least in part on the channel estimation measurement and the non-linear response of the PA configuration.

Abstract: The present disclosure involves determining base station (BS) beams for communicating between a UE and the BS. The BS may use sensor data or beam management reporting history to assist with determining one or more appropriate beams. The sensor data may include camera images, radar data, or lidar data, and be used to model the cell environment served by the BS. The BS may obtain reporting data from multiple UEs over time indicating the quality of beams received by the UEs at various locations in the cell environment and model the cell environment based on the reporting data. The BS may associate beams with possible UE locations within the cell environment and use the associations to determine beams for communicating with a UE after determining the UE's location.
