A transmitting device may determine a power amplifier operating mode associated with non-linear distortion of an input waveform for a power amplifier, where the power amplifier operating mode may be from a set of two or more power amplifier operating modes each associated with respective amounts of the non-linear distortion. The transmitting device may transmit a set of reference signals associated with estimation of a wireless channel for a transmission, and the transmitting device may further transmit an additional set of reference signals associated with non-linear distortion mitigation for the transmission. In some examples, a resource density of the additional set of reference signals may be based on the power amplifier operating mode. In some examples, the transmitting device may transmit an indication of the power amplifier operating mode, the resource density, or both, to a receiving device.

Methods, systems, and devices for wireless communication at a user equipment (UE) are described. A UE may receive control signaling including an indication of time and frequency resources that are configured for semiautonomous uplink scheduling from the UE. The UE may then transmit a semiautonomous uplink scheduling message including a request for a set of uplink transmission resources or parameters for an upcoming uplink transmission. The UE may determine the set of uplink transmission resources or parameters based on one or more interference measurements performed on the time and frequency resources that are configured for semiautonomous uplink scheduling from the UE. The UE may then receive, in response to transmitting the semiautonomous uplink scheduling message, a message approving or declining the request for the set of uplink transmission resources or parameters.

Semiautonomous uplink scheduling

Methods, systems, and devices for wireless communications are described. In some wireless communications systems, a user equipment (UE) may receive, from a base station, downlink control information (DCI) that activates periodic channel state information (CSI) reporting via uplink shared channel transmissions (e.g., via physical uplink shared channel (PUSCH) transmissions). The UE may then identify a trigger condition that triggers a transmission of both a first instance of a CSI report and a second instance of the CSI report within a period of the periodic CSI reporting. Based on the satisfaction of the trigger condition, the UE may transmit the first instance of the CSI report via a first uplink shared channel transmission and the second instance of the CSI report via a second uplink shared channel transmission, where both uplink channel transmissions are within the period of the periodic CSI reporting.

Semipersistent reporting of channel state information

If the LBT procedure is successful, the relay device may relay signals between the first wireless device and the second wireless device. Otherwise, the relay device may refrain from relaying signals between the first wireless device and the second wireless device. The described techniques may enable the relay device to operate with greater efficiency and reduced power consumption. The described techniques may also improve the reliability of communications between the first wireless device and the second wireless device.
