Selection from multiple transport blocks in uplink configuration grant (ul-cg) based on uplink buffer data

A method of wireless communication by a network entity, comprising:

• transmitting a configured grant for an uplink transmission occasion including a plurality of transport blocks (TBs), the configured grant indicating a first modulation and coding scheme (MCS) and a first quantity of layers for a first TB of the plurality of TBs, and a second MCS and a second quantity of layers for a second TB of the plurality of TBs;
• receiving an indication of whether a user equipment (UE) is transmitting on the first TB, the second TB, or the plurality of TBs for the uplink transmission occasion;
• and
• receiving the first TB, the second TB, or the plurality of TBs based on the indication.

An apparatus for wireless communication by a user equipment (UE), comprising:

• a memory;
• and
• at least one processor coupled to the memory, the at least one processor configured:
• to receive a configured grant for an uplink transmission occasion including a plurality of transport blocks (TBs), the configured grant indicating a first modulation and coding scheme (MCS) and a first quantity of layers for a first TB of the plurality of TBs, and a second MCS and a second quantity of layers for a second TB of the plurality of TBs;
• to select at least one of the first TB or the second TB, from the plurality of TBs, for an uplink transmission based on an amount of data stored in an uplink buffer;
• and
• to transmit the data in the at least one the first TB or the second TB that was selected.
