Abstract: Methods, systems, and devices for wireless communications are described. Techniques provide for reliable signal processing and amplification of downlink signals. A network entity may apply a digital pre-distortion (DPD) process to a signal for transmission to a user equipment (UE) and may apply a crest factor reduction (CFR) process to the output of the DPD process. The output of the CFR process may be amplified by a power amplifier and transmitted via a downlink transmission to the UE. The CFR process limits the peak power of the signal provided to the power amplifier (e.g., to a configured level), thereby reducing the peak to average power ratio (PAPR) of the signal provided to the power amplifier. The DPD process may compensate for non-linearities of the power amplifier. A training procedure for the DPD process may account for the CFR process applied after the DPD process.

Abstract: Methods, systems, and devices for wireless communications are described. A first wireless device may identify a set of data resource elements for transmitting data in one or more symbols periods. The first wireless device may generate, for the one or more symbol periods based on the set of data resource elements, a sequence of a set of pilot resource elements associated with the set of data resource elements, the sequence of the set of pilot resource elements including a phase tracking reference signal. The first wireless device may transmit, to a second wireless device in the one or more symbol periods, the set of data resource elements and the set of pilot resource elements. The second wireless device may decode a first subset of the set of pilot resource elements based on a second subset of the set of pilot resource elements to determine the phase tracking reference signal.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may receive, from a base station, an indication of a change in a non-linearity model associated with a power amplifier of the base station. The UE may update a model associated with the power amplifier based at least in part on the indication. The UE may further update at least one parameter associated with slicing received signals based at least in part on the indication. In some aspects, the UE may use at least two coefficients when slicing. Numerous other aspects are described.

Abstract: Certain aspects of the present disclosure provide techniques for downlink control information (DCI) format for power efficiency. A method that may be performed by a user equipment (UE) includes receiving, from a base station (BS), a first DCI message in a first symbol of a downlink control channel, the first DCI message comprising a portion of an identifier that consists of less than all parts of the identifier, the first symbol being one of a plurality of symbols in a time period. The method may also include, when the portion of the identifier corresponds to the UE, receiving downlink data via resources indicated by a second DCI message, the second DCI message received in a second symbol of the downlink control channel, the second DCI message indicating the resources for receiving downlink data, the second symbol being another one of the plurality of symbols in the time period.

Abstract: A first UE may transmit, to a second subset of one or more second UEs, one or more pilot signals associated with DPD training. The first UE may receive, from a third subset of the one or more second UEs, one or more feedback messages associated with DPD training. The one or more feedback messages may be based on the one or more pilot signals. Each second UE in the third subset of the one or more second UEs may correspond to one of the one or more feedback messages. The second UE may calculate one or more DPD parameters based on the one or more feedback messages. The second UE may transmit a first signal based on the calculated one or more DPD parameters.

Abstract: Methods, systems, and devices for wireless communications are described. For example, a user equipment (UE) may receive one or more reference signals from a base station. In some examples, the UE may receive the one or more reference signals over a channel for communications between the UE and the base station. The UE may measure a response of the channel based on the one or more reference signals received over the channel. In some examples, the UE may transmit a message indicating a set of channel coefficients. The set of channel coefficients may correspond to a two-dimensional (2D) model representative of the response. In some examples, the 2D model may include a spatial model and a time domain response of the channel.

Abstract: Methods, systems, and devices for wireless communications are described. A user equipment (UE) may transmit a first message indicating a capability of the UE to jointly modulate data with tone reservation signals on an individual subcarrier basis. Accordingly, the UE may receive a second message activating joint modulation of data with tone reservation signals for the UE. In some examples, the UE may also receive control signaling indicating various parameters to use for joint modulation of data with tone reservation signals. The UE may communicate with a base station over multiple subcarriers in accordance with the second message and the control signaling, where one or more of the multiple subcarriers carry data jointly modulated with tone reservation signals on an individual subcarrier basis. The described techniques may enable the UE to perform wireless communications with higher throughput, reduced power consumption, and improved spectral efficiency, among other benefits.

Abstract: This disclosure provides systems, methods, and apparatus, including computer programs encoded on computer-readable media, for a retransmission protocol that utilizes compressed feedback. Various implementations relate generally to a compressed feedback technique for hybrid automatic repeat request (HARQ). Upon receiving a compressed feedback value, a sending device may generate a retransmission codeblock. The retransmission codeblock may be derived from multiple codeblocks in a set of codeblocks. A receiving device can use the retransmission codeblock to obtain any failed codeblock in the set of codeblocks based on all other previously decoded codeblocks in the set of codeblocks. Thus, the receiving device does not need to indicate which codeblock in the set failed, but only needs to send a compressed feedback value that indicates which sets of codeblocks have had a single codeblock failure.

Abstract: Methods, systems, and devices for wireless communication are described. A communication device, such as a user equipment (UE) may receive a set of demodulation reference signal (DMRS) samples including a first subset of DMRS samples associated with a first power level and a second subset of DMRS samples associated with a second power level. The UE may perform a digital post distortion operation based on the first subset of DMRS samples associated with the first power level and the second subset of DMRS samples associated with the second power level. The UE may receive the wireless communication based on performing the digital post distortion operation.

The wireless device may receive a configuration for a resource pool for sidelink communication, the resource pool having a plurality of physical resource blocks (PRBs) including a first set of PRBs that are grouped in one or more sub-channels, each sub-channel having an equal number of PRBs, and a second set of PRBs that are not in the one or more sub-channels having the equal number of PRBs. The apparatus may transmit in the second set of PRBs. The second set of PRBs may not be monitored by a receiving device.
