Frequency interleaving across carriers of an aggregated bandwidth

An apparatus for wireless communication at a device, comprising:

• one or more memories;
• and
• one or more processors coupled to the one or more memories and configured to cause the device to:
• obtain a plurality of tones scheduled for an aggregated bandwidth including a plurality of carriers, the plurality of tones including a respective set of tones corresponding to each code block (CB) of a set of CBs, wherein the plurality of tones is arranged in a first sequence of blocks of tones, each block of tones of the first sequence of the blocks of tones including at least one corresponding tone from the respective set of tones corresponding to each CB;
• determine, based on the first sequence of the blocks of tones and an interleaving configuration associated with the aggregated bandwidth, an interleaved tone sequence for the plurality of tones, wherein the corresponding tones included in each block of tones of the first sequence of the blocks of tones are mapped to a respective carrier of the plurality of carriers based at least in part on the interleaved tone sequence;
• and
• output, using the interleaved tone sequence, the plurality of tones on the aggregated bandwidth.
