Abstract: Methods, systems, and devices for including power reporting for network power modification are described. That is, a user equipment (UE) and a base station may exchange signaling supporting an MPR update at the UE. In some examples, the UE may transmit, to the base station, a request for resources for performing channel measurements in accordance with a power reduction update associated with the UE. In response, the UE may receive, from the base station, an indication of a set of resources. In some examples, the UE may perform one or more channel measurements using the set of resources based on receiving the indication of the set of resources. In such examples, the UE may transmit, to the base station, a report indicating one or more power parameters associated with the power reduction update based on the one or more channel measurements.

Abstract: Aspects are provided for generation and transmission of MDMRS which allow matching of nonlinear model impact or properties between DMRS and data in DFT-s-OFDM waveforms as well as CP-OFDM waveforms. A UE transmits, to a network entity, an MDMRS generated from a DMRS. The MDMRS has a PAPR distribution matching a PAPR distribution of a signal including data in an uplink channel. A target PAPR of the MDMRS is based on a modulation scheme of the data. The UE also transmits the data in the uplink channel, where the uplink channel includes a PUCCH or a PUSCH. As a result of the ability of MDMRS to match the nonlinear impact of DMRS and PUSCH or PUCCH, the network entity may compensate for any EVM that may occur as a result of PAPR reduction by a nonlinear operator of the UE, and communication performance may thereby be improved.

The UE can determine a data message based on the first transmission and the second transmission.

Abstract: Methods, systems, and devices for wireless communications are described for physical layer signature feedback to enhance security in wireless communications. A user equipment (UE) and a network entity may apply a physical layer signature, such as an artificial physical layer impairment, to one or more physical layer signals that may be measured to identify a physical layer signature of the associated physical layer signal. The UE, upon receipt of a physical layer signal, may check if the identified signal includes a physical layer signature of a set of valid physical layer signatures. If the received physical layer signature matches a valid physical layer signature, the UE may operate in accordance with procedures associated with the signal. If the received physical layer signature does not match a valid physical layer signature, the UE may transmit a message to the network entity that indicates an unmatched physical layer signature.

The UE may perform a second waveform shaping stage on the output of the first waveform shaping stage to reduce an adjacent channel leakage ratio of the output of the first waveform shaping stage. The UE may then transmit a signal over the wireless channel based on an output of the second waveform shaping stage.
