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 (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 related to wireless communication systems and reducing peak-to-average-power ratio (PAPR) in MU-MIMO transmissions are provided. A base station (BS) generates a plurality of communication signals including data for a plurality of user equipment (UE) devices in a plurality of serving beam subspaces. The BS may also generate a peak-to-average-power ratio (PAPR) reduction signal for one or more of the plurality of communication signals. A first portion of the PAPR reduction signal is in a first serving beam subspace of the plurality of serving beam subspaces based on a first error vector magnitude (EVM) associated with a first UE of the plurality of UEs. A second portion of the PAPR reduction signal is in a non-serving beam subspace. The BS may also transmit, to the plurality of UEs, the plurality of communication signals and the PAPR reduction signal. Other features are also claimed and described.

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: 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: 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.

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: 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: Disclosed are techniques for wireless communication. In some aspects, a base station (BS) may determine a first planned transmit beam configuration of the first BS. The BS may obtain a second planned transmit beam configuration of a second BS. The BS may determine that a first planned transmit beam of the first planned transmit beam configuration will interfere with a second planned transmit beam of the second planned transmit beam configuration. The BS may modify the first planned transmit beam, the second planned transmit beam, or both, based on the interference determination.

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.
