Codeblock (cb) sorting and acknowledgement (ack) report compression

An apparatus for wireless communication, comprising:

• one or more memories, individually or in combination, having instructions;
• and
• one or more processors, individually or in combination, configured to execute the instructions and cause the apparatus to:
• generate a hierarchical ranking of each codeblock group (CBG) of a plurality of CBGs, wherein the hierarchical ranking is based on a first communication metric associated with a channel via which the plurality of CBGs are used to communicate data;
• output data for transmission via the plurality of CBGs;
• and
• obtain, from a wireless node, a report identifying a single CBG of the plurality of CBGs, wherein the single CBG is associated with a first ranking, and wherein the report is configured to request a retransmission of a portion of the data transmitted via:
• (i) the single CBG, and (ii) each of one or more other CBGs having a rank lower than the first ranking.

A method for wireless communications at a wireless node, comprising:

• generating a hierarchical ranking of each codeblock group (CBG) of a plurality of CBGs, wherein the hierarchical ranking is based on a first communication metric associated with a channel via which the plurality of CBGs are used to communicate data;
• obtaining data via the plurality of CBGs;
• and
• outputting a report identifying a single CBG of the plurality of CBGs, wherein the single CBG is associated with a first ranking, and wherein the report is configured to request a retransmission of a portion of the data obtained via:
• (i) the single CBG, and (ii) each of one or more other CBGs having a rank lower than the first ranking.
