Abstract: Method and apparatus for HARQ procedures for DVC. The apparatus sorts one or more bits of a payload based on a corresponding priority. The apparatus divides the payload into one or more groups based on the corresponding priority, where each of the one or more groups is encoded separately. The apparatus transmits, to a second wireless device, a video frame over a span of one or more slots based at least on a prioritized transmission of the one or more groups.

Abstract: Method and apparatus for compression in wireless communication systems. The apparatus compresses a signal based on an encoder scheme, wherein an encoded signal comprises at least a first CRC associated with a prediction index and a second CRC associated with a prediction information component. The apparatus transmits, to a second wireless device, the encoded signal comprising at least the first CRC associated with the prediction index and the second CRC associated with the prediction information component. The apparatus may be configured to compress the signal such that the signal comprises one or more parity bits, where the one or more parity bits correspond to a difference between a frame of the signal and at least one subsequent frame of the signal.

Abstract: Methods, systems, and devices for wireless communications are described. A user equipment (UE) may transmit multiple data segments of a video frame, where each data segment is mapped to respective physical resources. In some examples, the UE may receive a combined channel state feedback (CCSF) message indicating a predicted quantity of physical resources to successfully decode data segments of one or more video frames subsequent to the video frame. The UE may transmit data segments of the subsequent video frames according to the predicted quantity of physical resources. In some other examples, the UE may receive a segment feedback message associated with data segments that were unsuccessfully decoded by a network entity, where the segment feedback message may indicate a predicted quantity of physical resources to successfully decode the data segments. As such, the UE may retransmit the unsuccessfully decoded data segments according to the predicted quantity of physical resources.

Abstract: Apparatus, methods, and computer program products for wireless communication are provided. An example method may include establishing, with a second UE, a sidelink connection. The example method may further include communicating, with the second UE, a physical sidelink control channel (PSCCH) transmission carrying a PSCCH payload and a set of demodulation reference signal (DM RS) pilots, the PSCCH payload and the set of DM RS pilots being modulated based on a same cyclic shift (CS).

Abstract: Certain aspects of the present disclosure provide techniques for mapping two-stage sidelink control with multiple layer sidelink data channel. A first user equipment (UE) can rate-match a multiple-layer second stage of a two-stage sidelink control information (SCI) transmission as a single layer. The first UE transmits the multiple-layer second stage of the two-stage SCI, to a second UE, using multiple antenna ports.

Abstract: Methods, systems, and devices for wireless communications are described. The method may include a user equipment (UE) transmitting a capability message indicating a capability of the UE to support a positioning scheme for one or more reference signals within a precoding resource block group for a channel estimation procedure, receiving, based on the capability message, a control signal indicating a frequency allocation for the one or more reference signals for the channel estimation procedure, the frequency allocation for the one or more reference signals being based on the positioning scheme supported by the UE, receiving the one or more reference signals for the channel estimation procedure in accordance with the frequency allocation, and performing the channel estimation procedure using the one or more reference signals based on the precoding resource block group associated with the channel estimation procedure.

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.
