Abstract: Methods, systems, and devices for wireless communications are described. Some wireless communications networks may support carrier aggregation such that a user equipment (UE) may operate on both a primary cell using a first frequency range and a secondary cell using a second frequency range. In some cases, a beam failure associated with one or more beams of the secondary cell may be identified by the UE, and a beam failure recovery procedure may be triggered. The UE may send a beam failure recovery request message in an uplink data field of a physical uplink control channel (PUCCH) message to a base station of the primary cell. In response to the beam failure recovery request message, the base station of the primary cell may transmit a response to the UE which includes beam failure mitigation information.

Abstract: Methods, systems, and devices for wireless communications are described. A first wireless device may identify a set of data resource elements for transmitting data in one or more symbols periods. The first wireless device may generate, for the one or more symbol periods based on the set of data resource elements, a sequence of a set of pilot resource elements associated with the set of data resource elements, the sequence of the set of pilot resource elements including a demodulation reference signal. The first wireless device may transmit, to a second wireless device in the one or more symbol periods, the set of data resource elements and the set of pilot resource elements. The second wireless device may decode a first subset of the set of pilot resource elements based on a second subset of the set of pilot resource elements to determine the demodulation reference signal.

Abstract: Methods, systems, and devices for wireless communications are described. A channel engineering device may receive control signaling that triggers the channel engineering device to perform one or more angle of arrival (AoA) measurements on one or more reference signals and transmit an AoA measurement report based on the AoA measurements. The base station may process the AoA measurement report and send a control message that configures one or more settings at the channel engineering device. The base station may determine a beam shaping configuration that modifies the one or more settings at the channel engineering device to reflect, focus, refract, or filter signal energy of a transmission by the base station toward a user equipment (UE), a transmission by the UE toward the base station, or both. The base station and one or more UEs may communicate using the channel engineering device based on the beam shaping configuration.

Abstract: A method detecting allocation collisions from transmitting user equipments (UEs) in sidelink channel resources. The colliding allocations are detected and the quantity of allocation collisions is determined. A collision report is transmitted to other sidelink UEs within the coverage zone. The collision report or collision notification provides an indication of sidelink resources having identified colliding allocations. The identified allocation collisions may be pruned to remove potentially intentional collisions before collision report transmission.

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: A configuration to reduce a UE PAPR due to a transmission of a PAPR reduction signal into a UE null space. The apparatus establishes a connection with a base station. The apparatus transmits, to the base station, an SFMT report including an indication of a capability of the UE to process a signal form the base station that includes an SFMT transmission. The apparatus receives, from the base station, a downlink PAPR reduction signal based on the SFMT report of the UE.

Abstract: Wireless communications systems and methods related to beam refinement with simultaneous spatial-division multiplexed beams are provided. A user equipment (UE) receives, from a base station (BS), a plurality of reference signals in a set of beam directions. The receiving includes receiving, simultaneously during a first symbol, at least a first reference signal of the plurality of reference signals in a first beam direction of the set of beam directions and a second reference signal of the plurality of reference signals in a second beam direction of the set of beam directions, where the second beam direction is different from the first beam direction. The UE transmits, to the BS, a beam report indicating received signal measurements for two or more beam directions of the set of beam directions.

Abstract: Methods, systems, and devices for wireless communications are described for optimizing index modulated (IM) communications between a user equipment (UE) and a base station. The UE may identify a quantity of subcarriers for IM communications and transmit a message including an indication of the quantity of subcarriers to the base station. In some examples, the UE may transmit an indication of one or more subcarriers to exclude from IM communications. The base station may receive the indication of the quantity of subcarriers and/or the indication of the blacklisted subcarrier(s) and may determine a number of active subcarriers to be used based on at least the indication of the quantity of subcarriers. The base station may transmit an indication of the number of active subcarriers to the UE. The UE may process one or more received IM downlink signals based on the quantity of subcarriers.

Abstract: Methods, systems, and devices for wireless communication are described. A transmitting device may determine reconstruction information for a time-domain signal and may transmit the reconstruction information with the time-domain signal to a receiving device. The transmitting device may generate the reconstruction information based on estimates of how the receiving device may process the time-domain signal. For example, the transmitting device may apply a channel estimate to samples of the time-domain signal, and further perform clipping and quantization of the samples based on an estimated dynamic analog-to-digital converter (ADC) resolution of the receiving device. The transmitting device may generate the reconstruction information (e.g., using machine learning or other techniques) based on samples having the channel estimate applied and the clipped and quantized samples. The receiving device may process the received time-domain signal and use the reconstruction information to reconstruct the processed time-domain signal.
