Methods and apparatus for adaptive whitening

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

• a memory;
• and
• at least one processor coupled to the memory and configured to:
• receive at least one pilot resource and at least one data resource from a base station;
• identify interference cleaning data for the at least one pilot resource;
• determine whether a first interference affecting the at least one pilot resource is a same interference as a second interference affecting the at least one data resource based on identifying a transmission power difference between the at least one pilot resource and the at least one data resource;
• apply the interference cleaning data to the at least one data resource when the first interference is the same interference as the second interference, the interference cleaning data being applied to the at least one data resource when the transmission power difference is less than a threshold power;
• and
• apply modified interference cleaning data to the at least one data resource when the first interference is different than the second interference, the modified interference cleaning data being applied to the at least one data resource when the transmission power difference is greater than the threshold power.
