Methods to compute a signal-to-noise ratio estimate for a transport block

An apparatus for wireless communication at a network device, comprising:

• at least one processor;
• memory coupled to the at least one processor;
• and
• instructions stored in the memory and executable by the at least one processor to cause the apparatus to:
• transmit, to a user equipment (UE), a downlink transmission that comprises a set of parity bits;
• receive a feedback message from the UE that includes a feedback status indicator and additional information identifying a number of parity checks associated with the set of parity bits, the number of parity checks being based at least in part on parity checks of the set of parity bits that either failed a parity check procedure or satisfied the parity check procedure;
• and
• select a modulation and coding scheme for communications with the UE based at least in part on the feedback message.

A method for wireless communication at a user equipment (UE), comprising:

• monitoring for a downlink transmission from a network device, the downlink transmission comprising a set of parity bits;
• determining, based at least in part on the monitoring, a number of parity checks of the set of parity bits that either failed a parity check procedure or satisfied the parity check procedure;
• identifying, based at least in part on the monitoring and the number of parity checks, a feedback status indicator for the downlink transmission;
• and
• transmitting a feedback message that includes the feedback status indicator and additional information identifying the number of parity checks.
