    Abstract: When embedding a signal into a selected subcarrier of a multicarrier downlink waveform of regular data/control signaling, a base station modulates the embedded signal with a different modulation scheme than the other data in the downlink waveform. The base station nulls adjacent subcarriers to minimize interference at a low-power wake-up receiver of an IOE device(s). The IOE device wakes up the low-power wake-up receiver at scheduled times to listen for the signal. For synchronization signals, the IOE device corrects a local clock based on a correlation value of the signal to a predetermined sequence. For wake-up signals, the IOE device correlates whatever is detected at the antenna to a predetermined sequence and compares the correlation value to a predetermined threshold. If the threshold is met, the IOE device registers a wake-up signal and wakes the primary transceiver of the device. If not, the receiver goes back to sleep.

    Abstract: Methods, systems, and devices are described for wireless communication. A first device, such as a user equipment (UE) may be configured with a peak data rate that corresponds to the radio frequency (RF) capacity of a modem and a sustained data rate that corresponds to the baseband capacity. The first device may receive a set of data blocks during a transmission burst from a second device. The quantity of data blocks in the burst may be based on the peak data rate. The first device may store time domain samples or frequency tones for the data and then power down the RF components for an interval based on how long it will take to process the data. The first device may then process the data at the sustained data rate. After the rest interval, the first device may power up the RF components and receive another burst of data.

    Abstract: Various embodiments are disclosed for implementing joint non-linear interference cancellation (NLIC) in communication receivers with multiple receiver antennas to cancel or mitigate self-jamming interference from the same aggressor transmitter. A victim receiver may exploit the correlated nature of the interference signals received by the multiple receiver antennas to reduce the computational complexity of an NLIC scheme and improve performance. The victim receiver may select an Rx antenna/Rx chain that experiences the strongest interference from the aggressor transmitter and may perform a full NLIC operation using Tx data from the aggressor transmitter to estimate the strongest interference signal. The NLIC operation may estimate each remaining interference signal by applying a complex coefficient from a single-tap adaptive filter to the estimate of the strongest interference signal. The victim receiver may remove the estimated interference signals from the Rx signals of the respective Rx chains to cancel or mitigate the interference.

    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.

    Abstract: Methods, systems, and devices for wireless communications are described. A base station may receive an uplink transmission from a user equipment (UE) over a wireless channel and measure a post-digital post-distortion (post-DPOD) signal-to-noise ratio (SNR) of the uplink transmission. The base station may generate a power output back-off indication for the UE according to the post-DPOD SNR and a change in a post-DPOD noise level of the transmission between a non-linear distortion noise component and a thermal noise component. The base station may transmit the power output back-off indication and a downlink transmission to the UE. In response, the base station may receive an uplink transmission from the UE over the wireless channel. The uplink transmission may be based on the power output back-off indication, a signal quality metric of the downlink transmission, or both.
