Online spur detection and mitigation

1. A method for wireless communications at a user equipment (UE), comprising:

monitoring a plurality of reference signal tones of a first symbol period to identify a noise spur at a first reference signal tone of the plurality of reference signal tones;

generating a channel estimate corresponding to the first reference signal tone based at least in part on performing a spur reduction procedure on the first reference signal tone;

performing noise equalization on at least a second tone, of a second symbol period, adjacent to the first reference signal tone; and

demodulating the second tone based at least in part on the noise equalization and the channel estimate.

2. The method of claim 1, further comprising:

applying a high pass filter to the plurality of reference signal tones based at least in part on the monitoring, wherein identifying the noise spur is based at least in part on applying the high pass filter.

3. The method of claim 2, further comprising:

estimating a first channel noise level for at least a second reference signal tone of the plurality of reference signal tones;

detecting a second channel noise level for the first reference signal tone; and

identifying the noise spur at the first reference signal tone based at least in part on the first channel noise level and the second channel noise level.

4. The method of claim 3, further comprising:

determining to apply the high pass filter based at least in part on the first channel noise level differing from the second channel noise level by at least a threshold amount.

5. The method of claim 3, wherein a signal received via the first reference signal tone, and the second reference signal tone, is communicated using a same set of one or more parameters.

6. The method of claim 5, wherein the one or more parameters comprise a port combination, an orthogonal cover code set, a port comb, or any combination thereof.

7. The method of claim 2, wherein identifying the noise spur comprises:

identifying a location of a center of the spur, wherein the spur reduction procedure is performed corresponding to the location of the center of the spur.

8. The method of claim 1, wherein performing the noise equalization comprises:

performing a channel estimation procedure to the first reference signal tone to determine a first channel estimate;

adjusting the channel estimate by removing a noise spur estimate determined by the spur reduction procedure for the noise spur to generate the channel estimate corresponding to the first reference signal tone; and

performing a noise equalization procedure on the second tone of the second symbol using one or more noise whitening parameters corresponding to the noise spur estimate.
