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 communications are described. A user equipment (UE) may transmit first control information that is indicative of noise (e.g., phase noise, additive white gaussian noise (AWGN), or both) that impacts a spectral efficiency of a modulation and coding scheme (MCS). The MCS may be associated with a constellation of points that may be each representative of a respective candidate sequence of bit values encoded with a corresponding combination of signal amplitude and carrier phase. The UE may receive, based on transmitting the first control information, second control information that indicates a set of partitioning parameters indicative of a hierarchical partitioning of the constellation into a multiple subsets of points. As such, the UE may decode a message, modulated via the MCS, using the hierarchical partitioning indicated by the set of partitioning parameters.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may receive an indication of transmission spur frequency locations associated with transmissions of a network node. The UE may receive a communication from the network node, receiving the communication comprising performing one or more of channel estimation or noise estimation based at least in part on the transmission spur frequency locations. Numerous other aspects are described.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may transmit, to a network node, information that indicates a frequency dependent residual side band (FDRSB) cancellation capability. The UE may receive, from the network node, information that indicates a frequency domain (FD) allocation assigned to the UE to mitigate FDRSB interference at the UE based at least in part on the information that indicates the FDRSB cancellation capability. Numerous other aspects are described.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may transmit a frequency dependent residual side band (FDRSB) training signal on a first set of subcarriers that are lower than a carrier frequency and on a second set of subcarriers that are higher than the carrier frequency, a mirror of the first set of subcarriers about the carrier frequency being non-overlapping with the second set of subcarriers. The UE may receive an indication of FDRSB correction that is based at least in part on the FDRSB training signal. Numerous other aspects are described.

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: 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 determine a precoding matrix using a square matrix α, which may allow the network entity to dynamically combine (e.g., or not combine) data streams. 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.
