Abstract: Certain aspects of the present disclosure provide a technique for wireless communications by a user equipment (UE). The UE implements the technique to detect that a decoding failure of a first multiple input multiple output (MIMO) transmission, sent by a network entity on a first number of layers, is caused by a rank mismatch. The UE then sends a rank correction request to a network entity. The UE then combines samples from the first MIMO transmission and a second MIMO transmission, sent by the network entity using a space-time code (STC) with a second number of layers in response to the rank correction request, to recover data lost due to the decoding failure.

Abstract: Disclosed are techniques for wireless communication. In an aspect, a base station receives one or more signals indicative of a downlink compensation capability (e.g., an in-band capability to compensate for non-linear distortion, or an out-of-band capability to compensate for other FDM'd signal(s) to other UE(s), etc.) of at least one UE. The base station determines a set of downlink transmission requirements based on the downlink compensation capability of the at least one UE, and transmits data to the at least one UE in accordance with the set of downlink transmission requirements.

The methods further include transmitting, to the UE, a request for a TR report corresponding to an amount of TR locations, the amount of TR locations being associated with at least one of a PAPR gain or a UE performance gain. The methods further include receiving, from the UE, a TR report comprising an indication of the amount of TR locations based on one or more parameters, the one or more parameters including at least one of a UE speed, a Doppler spread, a delay spread, a SINR, a MCS, a rank indicating an amount of data layers, or a channel response, the amount of TR locations being associated with the one or more operating modes.

Abstract: Certain aspects of the present disclosure provide techniques for digital pre-distortion (DPD). An apparatus for wireless communication generally includes a power amplifier (PA); a first DPD circuit, a second DPD circuit, and a transmitter. The first DPD circuit is generally configured to: obtain an input signal; apply a first DPD to the input signal to generate a first resulting signal; and output the first resulting signal to the second DPD circuit. The second DPD circuit is generally configured to: obtain the first resulting signal from the first DPD circuit; apply a second DPD to the first resulting signal to generate a second resulting signal; and output the second resulting signal to the PA. The PA is generally configured to amplify the second resulting signal to generate an amplified second resulting signal. The transmitter is generally configured to transmit the amplified second resulting signal to a second apparatus.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a first user equipment (UE) may receive, from a second UE and using a first fast Fourier transform (FFT) window configuration, a physical sidelink control channel (PSCCH) signal associated with a physical sidelink shared channel (PSSCH) signal. The UE may identify, based at least in part on the reception of the PSCCH signal, one or more values of one or more parameters estimated from the PSCCH signal. The UE may select, based at least in part on the one or more values of the one or more parameters, a second FFT window configuration to be used to receive the PSSCH signal. The UE may receive, from the second UE, the PSSCH signal using the second FFT window configuration, Numerous other aspects are described.

Abstract: Methods, systems, and devices for wireless communications are described. In some examples, when a high subcarrier spacing (SCS) is used for sidelink communications, the user equipments (UEs) may use a modified sidelink slot structure for the sidelink communications. In one example, the slot structure may include at least two automatic gain control (AGC) symbols with at least one sidelink control channel symbol between the two AGC symbols. The UE may perform an AGC procedure during the two AGC symbols and the sidelink control channel symbol. In some examples, the slot structure may include bundled slots to minimize per slot overhead associated with AGC symbols and sidelink control channel symbols. For example, at a high SCS, the slot structure may include a first slot including multiple AGC symbols, Subsequent bundled slots may not include AGC symbols and/or sidelink control channel symbols.

Abstract: Methods, systems, and devices for wireless communications are described. The method includes communicating control signaling scheduling a sidelink transmission via a physical sidelink channel, receiving, by a first user equipment (UE), the sidelink transmission including one or more reference signals from a second UE via the physical sidelink channel based on the control signaling, and monitoring the physical sidelink channel based on time synchronization, frequency synchronization, or both, determined using the one or more reference signals.

Abstract: Methods, systems, and devices for wireless communications are described. In some wireless communications system, a wireless device may append, during a first encoding stage, a first set of cyclic redundancy check bits having a first size to each code block of a plurality of code blocks and may concatenate two or more code blocks from the plurality of code blocks into a first set of code blocks, each code block of the two or more code blocks including the appended first set of cyclic redundancy check bits. The wireless device may further append, during a second encoding stage, a second set of cyclic redundancy check bits having a second size to the first set of code blocks, and may transmit a message comprising the plurality of code blocks including the appended first set of cyclic redundancy check bits and the appended second set of cyclic redundancy check bits.
