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 an aspect of the disclosure, a method, a computer-readable medium, and an apparatus are provided. The apparatus may be a UE configured to receive a plurality of beams through a plurality of different receive beam directions, each of the beams including broadcast information on a PBCH. The apparatus may be further configured to determine, for each of a subset of the received beams, a log likelihood ratio (LLR) for coded bits of the broadcast information. The apparatus may be further configured to decode the broadcast information associated with each of the subset of the received beams, and determine a refined receive beam direction based on the determined LLRs and based on whether the broadcast information associated with each of the subset of the received beams fails to decode or is successfully decoded.

Abstract: Systems and methods to detect spurious responses (spurs) in association with mmWave wireless communications are described. Such spurs may originate internal to the receiver (internal spurs) or external to the receiver (external spurs) originated in the transmitter. Embodiments operate to identify received mmWave wireless communication signal spurs in symbols, or portions thereof, which do not have transmissions directed to the receiving device. mmWave spur detection implementations of embodiments can detect spurs in real-time operation of the receiving device. Such real-time spur detection facilitates operation by the receiving device to perform spur removal in real-time operation of the receiving device, thus enabling removal of both internal spurs and external spurs as well as dynamically adapting to different scenarios that cause different spurs. Other aspects and features are also claimed and described.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may determine a set of recommended base station transmit beams for full duplex operation based at least in part on measurements of a set of base station transmit beams and measurements of self-interference associated with the set of base station transmit beams. The UE may transmit a report that indicates a recommendation to use one or more of the set of recommended base station transmit beams for full duplex operation. Numerous other aspects are described.

Abstract: Embodiments include systems and methods for communicating information in a physical uplink control channel (PUCCH) message. A processor of a wireless device may configure a PUCCH message to include an uplink message in a short data field. The processor may send the PUCCH message including the short data field to convey the uplink message to a communication network. In some embodiments, the processor may receive data from a second wireless device in a downlink channel, and may generate an acknowledgement message responsive to the received data. The processor may configure the short data field to include the acknowledgement message, and may send the PUCCH message including the short data field that includes the acknowledgement message to acknowledge the received data.

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. In some systems, a user equipment (UE) may monitor sets of decoding candidates over a search space in each monitoring occasion to detect downlink control transmissions. Such a monitoring process may be resource intensive. To reduce the processing power involved in monitoring the control channel, a UE may measure resources associated with the downlink control channel to obtain a quality metric. The UE may compare the quality metric to one or more thresholds and may perform a decoding process on a set of configured decoding candidates for the downlink control channel based on the comparing. In some cases, if the channel quality is relatively good, the UE may perform a list decoding process using a list size less than a maximum list size or may perform partial data tone processing to reduce the processing complexity for some of the decoding candidates.

Abstract: Methods, systems, and devices for wireless communications are described to switch between waveform configurations based on an indicated modulation coding scheme (MCS) such that waveform switching may be signaled implicitly. A base station may configure a user equipment (UE) with a hybrid MCS table including MCS indexes associated with a first waveform configuration and MCS indexes associated with a second waveform configuration. The base station may schedule resources for an uplink transmission for the UE and may indicate an MCS index associated with the uplink transmission, using index from the MCS table. The UE may select a waveform configuration for the uplink transmission based on the MCS index. For example, the UE may compare the MCS index with a threshold MCS index of the hybrid MCS table and determine a waveform configuration associated with the MCS index based on whether the MCS index falls above or below the threshold.

Abstract: Methods, systems, and devices for wireless communications are described. Generally, the described techniques allow a channel engineering device (CED) to identify a suitable configuration for deflecting uplink transmissions from a user equipment (UE) to a base station. The base station may transmit control signaling to the CED indicating multiple configurations for deflecting uplink reference signals. The UE may then transmit the uplink reference signals to the CED, and the CED may deflect the uplink reference signals using the indicated configurations. The base station may receive the uplink reference signals from the UE via the CED, and the base station may perform measurements on the uplink reference signals. The base station may then identify a configuration for the CED to use to deflect subsequent transmissions from the UE to the base station based on the measurements, and the base station may transmit an indication of the configuration to the CED.

Abstract: Aspects of the disclosure relate to beam management techniques in a wireless communication system. A UE establishes a communication link with a base station and receives a set of transmit beams transmitted via a plurality of symbols in a sequential manner, wherein a respective transmit beam is transmitted in a respective symbol of the plurality of symbols. The UE measures, for each transmit beam in the set of transmit beams, a set of signal strengths corresponding to the respective transmit beam using a plurality of receive beams in the respective symbol, wherein a respective signal strength is measured based on a respective receive beam. The UE then sends a feedback message to the base station including at least an identification of a transmit beam having a highest measured signal strength among all sets of signal strengths measured for the set of transmit beams and the highest measured signal strength.
