    Abstract: Methods, systems, and devices for wireless communications are described. A user equipment (UE) may transmit a capability message indicating support for adaptive power amplifier back-off for uplink transmissions. The UE may receive, based at least in part on the capability message, an identifier for an adaptive power amplifier back-off scheme to be applied to an uplink transmission. The UE may perform the uplink transmission according to the adaptive power amplifier back-off scheme, wherein the adaptive power amplifier back-off scheme comprises a change to at least one of an error vector magnitude level for a power amplifier of the UE or an output power of the power amplifier of the UE, wherein the change triggers the power amplifier to operate in a non-linear region such that the uplink transmission includes a non-linear component.

    Abstract: Certain aspects of the present disclosure provide techniques for cyclic shift selection for physical sidelink control channel retransmissions. A method that may be performed by a first user equipment (UE) includes monitoring one or more sidelink control information (SCI) transmissions from one or more second UEs. The method generally includes determining, based on the one or more SCI, whether one or more collisions occur between one or more retransmissions of the one or more SCI transmissions by the one or more second UEs and a scheduled SCI transmission by the first UE. The method generally includes selecting a cyclic shift to use for the scheduled SCI transmission by the first UE based at least on the determination.

    Abstract: A base station transmits a first transmission using a first directional beam and determines an equivalent isotropic radiated power (EIRP) relationship between the first transmission and a physical downlink shared channel (PDSCH) for a user equipment (UE). The base station transmits, to the UE, an indication of the EIRP relationship between the first transmission and the PDSCH. Then, the base station transmits the PDSCH to the UE using the second directional beam. The UE uses the indication of the EIRP relationship to receive the PDSCH from the base station over the second directional beam.

    Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may receive interference assistance information associated with interference cancelation or suppression for one or more communications. The UE may transmit interference assistance feedback that indicates one or more parameters of interference cancelation or suppression based at least in part on the interference assistance information. The UE may receive a communication within a set of time and frequency resources associated with a multiple user (MU)-multiple-input multiple-output (MIMO) group, the MU-MIMO group associated with the interference assistance feedback. Numerous other aspects are described.

    Abstract: Certain aspects of the present disclosure provide techniques for relaying physical sidelink control channel in sidelink communications. A method that may be performed by a first user equipment (UE) includes receiving a sidelink control information (SCI) transmission from a second UE, the SCI pointing to one or more resources for a retransmission of the SCI by the second UE. The method may include transmitting the SCI to a third UE using the one or more resources for the retransmission of the SCI by the second UE.

    Abstract: In a wireless communication system, a peak to average power ratio (PAPR) may affect the efficiency of a power amplifier. To reduce a PAPR, a transmitting device may utilize a PAPR reduction precoding that changes a received signal without performance impact so the overall transmit PAPR is reduced. The transmitting device constructs a frequency domain (FD) response to the PAPR reduction precoding, estimates a channel to one or more receiving devices, and applies the PAPR reduction precoding to the estimated channel. The transmitting device constructs a multiple input multiple output (MIMO) precoding matrix considering the FD response of the PAPR reduction precoding and applies the MIMO precoding matrix and the PAPR reduction precoding to an FD signal. A receiving device applies the FD response conjugated to a received FD signal from the transmitting device and processes at least a received reference signal based on the PAPR reduction precoder.

    Abstract: A method of secure wireless communication is performed by a user equipment (UE). The method receives, from a base station, sub-messages of a secured physical layer message, each sub-message received over a different beam. The method also decodes the sub-messages into decoded message segments. Further, the method reconstructs the secured physical layer message from the decoded message segments. A method of secure wireless communication by a base station includes receiving, from a user equipment (UE), a list of candidate beams for transmission and a reception metric for each of the candidate beams. The method also includes segmenting a secured physical layer message into sub-messages. The method further includes transmitting, to the UE, a control message indicating a structure of the secured message and a transmit beam for each of the plurality of sub-messages; and transmitting, to the UE, each sub-message over a different transmit beam of the candidate beams.
