Methods and apparatus for mapping transport blocks

A receiving device, comprising:

• one or more transceivers;
• one or more memories including instructions;
• and
• one or more processors communicatively coupled with the one or more transceivers and the one or more memories, the one or more processors are configured to execute the instructions to:
• receive, from a transmitting device, a transport block including one or more code blocks having a plurality of bits configured to be separated into at least a first layer set and a second layer set of a plurality of layer sets in a first subband a plurality of subbands, and a third layer set and a fourth layer set of the plurality of layer sets in a second subband of the plurality of subbands, each layer set of the plurality of layer sets of each subband of the plurality of subbands has a corresponding modulation order;
• and
• read the plurality of bits in the one or more code blocks by de-interleaving:
• first bits in the first layer set, second bits in the second layer set, third bits in the third layer set, and fourth bits in the fourth layer set separately,
• first interleaved bits based on the transmitter interleaving first bits in the first layer set and second bits in the second layer set and second interleaved bits based on the transmitter interleaving third bits in the third layer set and fourth bits in the fourth layer set,
• first interleaved bits based on the transmitter interleaving first bits in the first layer set and third bits in the third layer set and second interleaved bits based on the transmitter interleaving second bits in the second layer set and fourth bits in the fourth layer set, or
• interleaved bits based on the transmitter jointly interleaving first bits in the first layer set, second bits in the second layer set, third bits in the third layer set, and fourth bits in the fourth layer set.
