Abstract: A phase tracking reference signal (PTRS) may be enhanced to carry data encoded with a relative low modulation and coding scheme (MCS). A receive device may receiving a data channel, the data channel including a transport block encoded using a first MCS. The receiving device may receiving a PTRS interleaved with the data channel. The PTRS is encoded with the second MCS that is lower than the first MCS. The receiving device may decode the PTRS to determine PTRS data. The receiving device may track phase noise using the PTRS data as a transmitted sequence of the PTRS. The receiving device may decode the transport block for the data channel based on the first MCS and the tracked phase noise.

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: Methods, systems, and devices for wireless communications are described. In one example, a receiving device (e.g., a UE) may transmit, to a transmitting device (e.g., a base station), a capability indicator indicating a capability of the receiving device to perform peak reconstruction using soft metrics (e.g., expected value, covariance) on symbol decisions. The receiving device may receive, from the transmitting device and based on the capability indicator, control signaling indicating a clipping level applied to generate a signal and a subset of peaks clipped from the signal. The receiving device may receive the signal generated in accordance with the control signaling from the transmitting device and may decode a reconstructed signal based on performing the peak reconstruction on the signal using the soft metrics on symbol decisions, the clipping level, and the subset of the peaks clipped from the signal.

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: 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.

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 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 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: 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.
