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: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment may transmit a request, for an uplink transmission or a downlink transmission, for data aided phase tracking reference signals (PT-RSs); and communicate the uplink transmission or the downlink transmission based at least in part on the request. Numerous other aspects are provided.

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: Methods, systems, and devices for wireless communications are described. In one example, a transmitting device may identify first and second portions of data to include in a data transmission. The transmitting device may encode the second portion by a configuration of a first subset of resource elements. The transmitting device may transmit, via the data transmission, first signals representative of the first portion over the first subset and one or more second signals over a second subset of resource elements. A receiving device may receive the data transmission and may identify that the one or more second signals include content other than data of the data transmission. The receiving device may decode the first signals in order to identify the first portion and the configuration in order to identify the second portion. The receiving device may refrain from decoding the one or more second signals based on the identifying.

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: 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 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.
