Techniques for pre-opening notch filter in wireless communications system

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

• a processor;
• memory coupled with the processor;
• and
• instructions stored in the memory and executable by the processor to cause the apparatus to:
• receive one or more downlink grants;
• activate a notch filter at a first time, wherein the first time is at least a threshold period of time prior to a beginning of a first downlink transmission associated with the one or more downlink grants;
• filter interference from a signal at the UE using the activated notch filter;
• and
• communicate with a base station in accordance with the one or more downlink grants and based at least in part on filtering the interference.

A non-transitory computer-readable medium storing code for wireless communication at a user equipment (UE), the code comprising instructions executable by a processor to:

• receive one or more downlink grants;
• activate a notch filter at a first time, wherein the first time is at least a threshold period of time prior to a beginning of a first downlink transmission associated with the one or more downlink grants;
• filter interference from a signal at the UE using the activated notch filter;
