Lossy compressed feedback for multiple incremental redundancy scheme (MIRS)

A wireless device, comprising:

• a processor configured to:
• determine first decoding results for a number of code blocks in a first feedback group received from a sending device;
• select a first compression codebook from among a group of allowed codebooks indicated by the sending device for use in generating a feedback message for the first decoding results based at least in part on a probability of successful decoding of each code block in the first feedback group, wherein the selected first compression codebook provides a lowest rate of distortion of the plurality of codebooks based on the first decoding results;
• generate a first feedback message for the first decoding results using the selected first compression codebook;
• and
• send the first feedback message to the sending device.

A wireless device, comprising:

• means for determining first decoding results for a number of code blocks in a first feedback group received from a sending device;
• means for selecting a first compression codebook from among a group of allowed codebooks indicated by the sending device for use in generating a feedback message for the first decoding results based at least in part on a probability of successful decoding of each code block in the first feedback group, wherein the selected first compression codebook provides a lowest rate of distortion of the plurality of codebooks based on the first decoding results;
• means for generating a first feedback message for the first decoding results using the selected first compression codebook;
• and
• means for sending the first feedback message to the sending device.

A non-transitory processor-readable storage medium having stored thereon processor-executable instructions to cause a processor of a wireless device to perform operations comprising:

• determining first decoding results for a number of code blocks in a first feedback group received from a sending device;
• selecting a first compression codebook from among a group of allowed codebooks indicated by the sending device for use in generating a feedback message for the first decoding results based at least in part on a probability of successful decoding of each code block in the first feedback group, wherein the selected first compression codebook provides a lowest rate of distortion of the plurality of codebooks based on the first decoding results;
• generating a first feedback message for the first decoding results using the selected first compression codebook;
• and
• sending the first feedback message to the sending device.
