Techniques and apparatuses for channel state information feedback performance for introduction of 64-qam in machine type communication devices

A user equipment for wireless communication, comprising:

• a memory;
• and
• at least one processor, operatively coupled to the memory, the memory and the at least one processor configured to:
• determine channel state information (CSI) feedback based at least in part on a channel quality information (CQI) table and a configured CSI reference resource size of the user equipment,
• wherein at least one of the CSI feedback or the CQI table is modified based at least in part on a modulation configuration of the user equipment;
• and
• report the CSI feedback.

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

• a memory;
• and
• at least one processor, operatively coupled to the memory, the memory and the at least one processor configured to:
• receive a grant for downlink traffic, wherein the UE is capable of using a first modulation order corresponding to a first modulation and coding scheme (MCS) table and a second modulation order corresponding to a second MCS table;
• and
• decode the downlink traffic according to the first MCS table or the second MCS table based at least in part on whether the grant is received in a UE-specific search space or a common search space.
