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.

Separate predictions for video compression for XR

Methods, systems, and devices for wireless communication are described. A transmitter device may encode information for a message using a spinal code. The transmitter device may divide the information into sets of bits each including a variable quantity k of bits, and map the sets of bits to symbols to generate a message. The transmitter device may transmit the symbols in an order based on the k values (symbols with smaller k values at the beginning of the message and larger k values at the end). Based on receiving the message, a receiver device may identify the k of each symbol and decode the symbols. The receiver device may identify a partial codeword or determine a likelihood of error associated with the message, which the receiver device may indicate via a feedback message. The transmitter device may retransmit a portion of the message based on the feedback.

Coding enhancement using spinal codes

Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a network node may obtain a demodulation reference signal (DMRS) having a constant envelope in a time domain. The network node may generate a communication signal based at least in part on multiplexing the DMRS with a plurality of data resource elements. Numerous other aspects are described.
