Processing of portions of a transport block that fails a cyclic redundancy check

A base station for wireless communication, comprising:

• a memory;
• and
• one or more processors, coupled to the memory, configured to:
• transmit configuration information indicating that a user equipment (UE) is to perform log likelihood ratio (LLR) calculations for fewer than all parts of a transport block (TB) based at least in part on a determination, by the UE, that the TB is likely to fail a cyclic redundancy check (CRC), the determination that the TB is likely to fail the CRC being based at least in part on one or more of the determination that the TB is likely to fail the CRC based at least in part on one or more of channel state information of a channel on which the UE receives the TB or an attempt to receive a previous TB;
• and
• receive an indication of the fewer than all parts of the TB for which the UE performed the LLR calculations.

A method of wireless communication performed by a user equipment (UE), comprising:

• receiving a transport block (TB);
• performing log likelihood ratio (LLR) calculations on fewer than all parts of the TB based at least in part on a determination, by the UE, that the TB is likely to fail a cyclic redundancy check (CRC),
• the determination that the TB is likely to fail the CRC based at least in part on one or more of channel state information of a channel on which the UE receives the TB or an attempt to receive a previous TB, and
• the determination that the TB is likely to fail the CRC being further based at least in part on a determination, by the UE, that performing the LLR calculations on the fewer than all the parts of the TB improves a likelihood of passing a subsequent CRC in a re-transmission of the TB;
• and
• transmitting an indication of the fewer than all the parts of the TB for which the UE performed the LLR calculations.
