Abstract: An apparatus for wireless communication includes a receiver and a transmitter that is configured to transmit a signal during a first slot. The signal has a power level that is associated with a transmission that is to occur during the first slot or during a second slot after the first slot. The signal is distinct from the transmission. The first slot and the second slot occur during a sub-frame time interval associated with a first cellular vehicle-to-everything (CV2X) wireless communication protocol, and the first slot and the second slot are associated with a second CV2X wireless communication protocol different than the first CV2X wireless communication protocol. The transmitter is further configured to perform the transmission during the second slot based on the power level.

Abstract: Methods, systems, and devices for wireless communications are described. A user equipment (UE) may perform online spur detection and mitigation scheme. The UE may identify spurs during operation, in real time, and apply cancelation and noise equalization to address identified spurs. The UE may apply a high pass filter to reference signals. During a symbol, the UE may apply the high pass filter by estimating the channel on one or more neighbor tones (e.g., tones of higher frequency and tones of lower frequency that also carry reference symbols). Because the UE may assume that a channel will generally be smooth, and that noise may vary slowly or steadily across frequency resources, the UE may compare the channel noise of a particular tone to an average or normalized channel noise of the one or more neighbor tones.

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: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a mobile station may transmit an indication of support for one or more candidate kernels for digital post distortion (DPoD) operations. The mobile station may receive a downlink communication based at least in part on the indication of support for the one or more candidate kernels for DPoD operations. Numerous other aspects are described.

Abstract: Methods, systems, and devices for wireless communications are described. A user equipment (UE) may transmit, to a base station, a control message indicating a capability of the UE to identify and report a reciprocity parameter between downlink communications and uplink communications of a channel between the UE and the base station. In some examples, the base station may request a reciprocity report from the UE. The UE may identify a reciprocity parameter based on one or more parameters associated with an array of antennas at the UE. The reciprocity parameter may indicate a reciprocity between an uplink beam and a downlink beam, such as a degree of overlap between the uplink beam and the downlink beam. The UE may report the reciprocity parameter via a reciprocity report to the base station. In some examples, the base station may identify one or more parameters based on the reciprocity report.

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: Methods, systems, and devices for wireless communications are described. A user equipment (UE) may perform both a channel estimation and a non-linearity estimation (e.g., a power amplifier (PA) model estimation) on a demodulation reference signal (DMRS) transmitted by a base station. For example, the DMRS may include two portions that correspond to two peak-to-average power ratio (PAPR) values. Low PAPR values may enable the UE to perform the channel estimation, and high PAPR values may enable the UE to perform the PA non-linearity estimation. Accordingly, a first portion of the DMRS may correspond to a lower PAPR value, and the second portion of the DMRS may correspond to a higher PAPR value. In some examples, the base station may signal different parameters for each portion of the DMRS to the UE, or the UE may use fixed values to receive each portion of the DMRS.

Abstract: Disclosed are techniques related to wireless communication system in which multi-level encoded modulation (MLCM) is applied to non-coherent communication. In the proposed techniques, a small fraction of differential phase rotations or bits participating in differential symbol coding are protected with strong codes while other complementary differential phase rotations or bits are protected with weaker codes. Compared to conventional non-coherent communication techniques in which a uniform protection is applied to any fraction of differential phase rotation or any bit of a differential symbol, the proposed MLCM approach enables more spectrally efficient scheme.

Abstract: Methods, systems, and devices for wireless communications are described, including a movable relay location variance report. The movable relay location variance report may enable more robust and accurate communications between a control node (e.g., a user equipment (UE) and a base station) and a movable relay (e.g., a drone) equipped with a reconfigurable intelligent surface (RIS). In some aspects, the location variance report may characterize the variance of the drone's location and transmit the information to the UE, the base station, or both. The location variance report may influence the control node beam width, the drone location, and an angle at which the drone may position a RIS. The control node may indicate an adjusted set of parameters to the drone based on receiving the location variance report.
