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: 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.

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: 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: 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.
