Code-block bit interleaving for flexible spectrum integration or carrier aggregation sub-bands

A method for wireless communication by a network entity, the method comprising:

• receiving information indicative of a mapping between an input code-block (CB) bit sequence and a plurality of sub-bands;
• generating an interleaved CB bit sequence based on application of the mapping to a particular CB bit sequence, wherein each sub-band of the plurality of sub-bands is mapped to a respective subset of coded bits of a plurality of coded bits according to the mapping, wherein the particular CB bit sequence includes the plurality of coded bits, and wherein the plurality of coded bits includes a plurality of subsets of coded bits;
• and
• outputting, based on the interleaved CB bit sequence, a plurality of modulated symbols.

A network entity for wireless communication, comprising:

• a processing system configured to:
