Change of SCS from 30 kHz to 60 kHz

Hello Experts.

Did anybody experience the change of SCS from 30KHz to 60KHz?

Could I know for which reason you want to change the SCS from 30 to 60?

To see the possibility to change it for latency, throughput… Or any improvement to be observed.

It will reduce latency but it will not improve throughput.

Thanks.

What’s the drawbacks for this change?
Any idea?
