Code block group retransmission

A method of wireless communication performed by a transmitter device, comprising:

• transmitting, using a plurality of codewords, a plurality of code block groups,
• wherein the plurality of codewords includes a first codeword associated with a first set of code block groups, of the plurality of code block groups, and a second codeword associated with a second set of code block groups of the plurality of code block groups;
• and
• retransmitting, after a failure associated with at least one code block group of the first set of code block groups, the at least one code block group using the first codeword;
• and
• transmitting, after the failure associated with the at least one code block group of the first set of code block groups and concurrently with the retransmitting, a new transport block using the second codeword.

A transmitter device for wireless communication, comprising:

• memory;
• and
• one or more processors coupled to the memory, the memory and the one or more processors configured to:
• transmit, using a plurality of codewords, a plurality of code block groups,
• wherein the plurality of codewords includes a first codeword associated with a first set of code block groups, of the plurality of code block groups, and a second codeword associated with a second set of code block groups of the plurality of code block groups;
• and
• retransmit, after a failure associated with at least one code block group of the first set of code block groups, the at least one code block group using the second codeword.
