5G PT-RS frequency density and time density in FR2

For 5G PT-RS in FR2, If we set frequency density Kref =2 and time density Lptrs = 1 the PT-RS will be transmitted or not?

To be clear, I need to make time density to be low since high density in the time domain produces a phase noise.

So, is it better to choose 2 or 4?

I think it should be transmitted, as 3GPP specifies time density to be {1,2,4} and frequency density to be {2,4}.

In that case 2 would be a better choice, as higher time density of PTRS would lead to more accurate phase noise estimation.

For frequency density as 2 and time density as 1, right?

Yes, I think so.
