Abstract: Methods, systems, and devices for wireless communication are described. A user equipment may transmit, to a serving network entity, a message requesting a quantity of transmission layers scheduled to be used by one or more neighbor network entities for communication within a communication resource. In response, the user equipment may receive, from the serving network entity, an indication of the quantity of transmission layers scheduled to be used by one or more neighbor network entities for communication within the communication resource. The user equipment may apply the quantity of transmission layers for the communication resource to a rank-aware interference rejection algorithm and may use the rank-aware interference rejection algorithm to improve a noise covariance matrix estimation. When receiving a downlink message, from the serving network entity via the communication resource, the improved noise covariance matrix estimation may be used to mitigate interference at the communication resource.

Abstract: Methods, systems, and devices for wireless communications are described. A network entity may indicate whether a user equipment (UE) is to update an estimation of non-linear characteristics of a power amplifier of the network entity. The network entity may transmit, to the UE, control signaling and data signaling in a slot. The control signaling may indicate whether the UE is to update the estimation of the non-linear characteristics. If the control signaling indicates to update the estimation, the UE may perform a correction on pilot signals of the data channel to obtain an updated estimation, and the UE may decode the data signaling based on the updated estimation. If the control signaling does not indicate to update the estimation, the UE may decode the data signaling based on a previous estimation of the non-linear characteristics.

Abstract: Methods, systems, and devices for wireless communications are described. A network entity may indicate to a user equipment (UE) (e.g., in a downlink control message) a capability of the network entity to disable power amplifiers for downlink transmissions. In response to the capability indication, the UE may estimate and report to the network entity the delay spread and antenna array loss threshold of a downlink signal. Based on the reported delay spread and antenna array loss threshold, the network entity may determine a quantity of power amplifiers that may be disabled for downlink transmission without reducing the received signal power at the UE below a minimum threshold. The power amplifiers that the network entity disables may be the power amplifiers with input powers less than a threshold (e.g., less than a highest input power by a threshold).

Abstract: Methods, systems, and devices for wireless communications using a singular value decomposition (SVD) combiner precoder are described. The described techniques may enable a network entity to determine which streams of a set of multiple data streams to combine in the SVD combiner precoder to increase a lowest signal-to-noise ratio of the set of multiple data streams, and which streams of the multiple streams to leave separate.

The network entity may transmit an indication to a UE indicating which streams the network entity will combine and which streams the network entity will not combine. The UE may accordingly demodulate the non-combined streams with a relatively less complex demodulator and may demodulate the combined streams with a relatively more complex demodulator.

Abstract: Various aspects are described herein for frequency dependent residual sideband (FDRSB) cancellation. A network node may measure an FDRSB distortion and may calculate a thermal noise based at least in part on the FDRSB distortion and a received signal-to-noise ratio (SNR). The network node may identify, based at least in part on the thermal noise, the FDRSB, and a modulation and coding scheme (MCS), whether to enable or disable FDRSB cancellation at a user equipment (UE). The network node may transmit an FDRSB cancellation message that indicates for the UE to enable FDRSB cancellation or that indicates for the UE to disable FDRSB cancellation, and the UE may selectively perform FDRSB cancellation based at least in part on the FDRSB cancellation message. This may reduce UE processing resources, UE energy consumption, and latency at a demodulator of the UE.

Abstract: Dysfunctional or exhausted T cells arise in chronic diseases including chronic viral infections and cancer, and express high levels of co-inhibitory receptors. Therapeutic blockade of these receptors has clinical efficacy in the treatment of cancer. While co-inhibitory receptors are co-expressed, the triggers that induce them and the transcriptional regulators that drive their co-expression have not been identified. The immunoregulatory cytokine IL-27 induces a gene module in T cells that includes several known co-inhibitory receptors (Tim-3, Lag-3, and TIGIT). The present invention provides a novel immunoregulatory network as well as novel cell surface molecules that have an inhibitory function in the tumor microenvironment. The present invention further provides the novel discovery that the transcription factors Prdm1 and c-Maf cooperatively regulate the expression of the co-inhibitory receptor module.

The cancelling may be in accordance with: the current frequency-dependent subband impairment estimate in accordance with the second message including the command to maintain the current frequency-dependent subband impairment estimate, or an update to the current frequency-dependent subband impairment estimate in accordance with the second message including the command to update the current frequency-dependent subband impairment estimate.

Abstract: Methods, systems, and devices for wireless communications are described. A user equipment (UE) may transmit a capability message indicating a capability of the UE to estimate a frequency domain imbalance between an in-phase portion of a transmission chain of a network entity and a quadrature-phase portion of the transmission chain of the network entity. The UE may receive, based on the capability message, an indication of a coherence bandwidth associated with the frequency domain imbalance. The coherence bandwidth may indicate a quantity of subcarriers (SCs) over which a characteristic of the frequency domain imbalance (e.g., a change in amplitude of the frequency domain imbalance) satisfies a threshold. The UE may perform an estimation of the frequency domain imbalance based on the coherence bandwidth. In some examples, the UE may receive downlink signals from a network entity and may perform a correction of the downlink signals based on the estimation.
