Adjusting LTE Carrier Bandwidth from 10MHz to 15MHz

[radioexpert]

Hello 4G Ericsson Experts!

I am planning to increase the LTE carrier bandwidth from 10 MHz to 15 MHz. Before proceeding, should I adjust the neighbor parameters to avoid any impact on handover?

Also, will changing the bandwidth directly have no effect?

For Huawei, if the EARFCN remains unchanged, you should be fine. I believe the same applies to Ericsson

However I think when defining frequencies from 3G to 4G you do need to update the bandwidth size.
