    Abstract: Certain aspects of the present disclosure provide techniques for simulating a receiver for link adaptation. A method for wireless communications by an apparatus includes obtaining, from an UE, parameters of a UE receiver; determining channel characteristics of a communication channel between the apparatus and the UE based on a measurement of a signal received from the UE; estimating a response of the UE receiver communicating on the communication channel having the channel characteristics based on a digital representation of the UE receiver, wherein the digital representation of the UE receiver is based on the parameters of the UE receiver; determining, based on the estimated response, at least one parameter for communication on the communication channel with the UE; sending, to the UE, an indication of the at least one parameter; and communicating with the UE in accordance with the at least one parameter.

    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: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may receive a configuration for receiving or calculating an interference parameter based, at least in part, on one or more estimated power delay profiles (PDPs), one or more precoding rules, and one or more kernels, the one or more estimated PDPs being associated with one or more communication channels. The UE may receive a configuration for applying the interference parameter to a transmission having a power near a compression point of a power amplifier to reduce transmission non-linearities. Numerous other aspects are described.

    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: This disclosure provides systems, methods and apparatus, including computer programs encoded on computer storage media, for early termination of decoding attempts, including decoding attempts associated with physical downlink control channel (PDCCH) candidates that are encoded using a rateless code. In some aspects, a transmitting device may encode a message using a rateless code associated with a cumulative encoding of various portions of the message, and using a device identifier or group identifier as an input to the encoding. Similarly, a receiving device may receive an encoded signal over candidate resources and may attempt to decode the signal in accordance with the rateless code and using a device identifier or a group identifier as an input to the decoding. As such, intended or non-intended receiving device may be able to evaluate whether to proceed with a decoding attempt or to terminate a decoding attempt at a relatively early stage.

    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: Certain aspects of the present disclosure provide techniques for envelope tracking schemes for a node in a wireless communication network. One aspect provides a method for wireless communication by a transmitter device. The method generally includes: combining envelopes associated with subbands of an input signal to be amplified for transmission based on a combination function; amplifying, via an amplifier, the input signal to generate a transmission signal, the input signal being amplified based on a combined envelope signal, representing the combination of the envelopes, received at a supply input of the amplifier; and transmitting the transmission signal to a receiver device.

    Abstract: A user equipment (UE) may transmit, to a network node, an indication of support for a decoder success prediction capability. The network node may obtain the indication of support by the UE for the decoder success prediction probability. The network node may output a transmission for the UE including one or more parameters based on the indication of support by the UE for the decoder success prediction capability. The UE may receive the transmission including one or more code blocks based on the indication of support for the decoder success prediction capability. The network node may optimize a multiple incremental redundancy scheme (MIRS) schedule for at least one of transmitting the transmission or retransmitting the transmission based on the indication of support by the UE for the decoder success prediction capability. The transmission may include the MIRS schedule.
