Transport block size determination for a transmission time interval

A method for wireless communications at a base station, comprising:

• identifying a user equipment (UE) capability to support a modulation scheme;
• identifying a plurality of TBS values based at least in part on the modulation scheme;
• mapping a scaled transport block size (TBS) value that is based at least in part on a length of a transmission time interval (TTI) for communicating with the UE to a TBS value of the plurality of TBS values;
• and
• communicating, with the UE during the TTI, data on a transport block having a size corresponding to the mapped TBS value.

An apparatus for wireless communication, comprising:

• a processor,
• memory in electronic communication with the processor;
• and
• instructions stored in the memory and executable by the processor to cause the apparatus to:
• determine whether the apparatus is configured to support a modulation scheme;
• identify a plurality of TBS values based at least in part on whether the apparatus is configured with the modulation scheme;
• identify a scaled transport block size (TBS) value that is based at least in part on a length of a transmission time interval (TTI);
• map the scaled TBS value to a TBS value of the plurality of TBS values;
• and
• communicate, with a base station during the TTI, data on a transport block having a size corresponding to the mapped TBS value.
