Abstract: Methods, systems, and devices for wireless communications are described. A second wireless device may perform an enhanced non-linearity correction procedure. For example, the second wireless device may transmit, to a first wireless device, a capability report and, additionally, or alternatively, a request for a statistical attribute report associated with a power amplifier (PA) of the first wireless device. The statistical attribute report may include one or more statistical attributes associated with one or more PA coefficients for the PA. The second wireless device may receive, in response to the request, the statistical attribute report and a data signal based on the one or more PA coefficients for the PA from the first wireless device. The second wireless device may perform, based on the statistical attribute report and the data signal, an enhanced non-linearity correction procedure on the data signal.

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 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: Apparatus, methods, and computer program products for wireless communication are provided. An example method may include transmitting, to a network node, information associated with a first quantity of effective downlink transmit (Tx) antennas associated with the UE. The example method may further include receiving, from the network node, a transmission indicative of a set of precoding functions for a set of Tx antennas associated with the network node, where each precoding function of the set of precoding functions is associated with a respective group of multiple Tx antennas of the set of Tx antennas associated with the network node, and where a second quantity of precoding functions is smaller than or equal to the first quantity of the effective downlink Tx antennas. The example method may further include receiving, from the network node, a second transmission based on the set of precoding functions.

Abstract: Methods, systems, and devices for wireless communication are described. A user equipment (UE) may receive an indication that the UE is to apply a digital-post distortion (DPoD) procedure to a received signal to reduce non-linearities of the received signal. In some examples, the UE may determine one or more autocorrelation values for a power delay profile (PDP) of a channel, receive an indication of a matrix, and identify coefficients (e.g., b-coefficients) for use in the DPoD procedure based on multiplying the autocorrelation values and the matrix. Alternatively, a network entity may determine the autocorrelation values indicate them to the UE for use in identifying the coefficients. In some other cases, the network entity may use the autocorrelation values and the matrix to determine the coefficients and then may indicate the coefficients to the UE. The UE may apply the DPoD procedure to the received signal using the coefficients.

Abstract: Methods, systems, and devices for wireless communications are described. The described techniques may provide for an adaptive digital post-distortion (DPoD) procedure and reporting of modulation and coding scheme (MCS) indices for communications between a user equipment (UE) and a network entity. The UE may select a kernel from a set of kernels indicated by the network entity for a DPoD procedure based on a target error vector magnitude (EVM). Additionally, or alternatively, the UE may determine a limitation for an MCS index for the network entity to use in communications with the UE based on a power limitation of the UE and an EVM associated with the MCS. The network entity and the UE may accordingly communicate using the MCS limitation requested by the UE and the determined DPoD kernel.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a network node may precode communications with a precoding configured to improve non-linearity (NL). Some aspects more specifically relate to a user equipment (UE) obtaining power amplifier (PA) NL coefficients associated with NL of PAs of a network node. The UE may transmit an indication of the PA NL coefficients to the network node, which may use the indication to select precoding configured to improve reception of communications transmitted with PA NL or to improve decoding of communications transmitted using the precoding.

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: 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.
