Hanover between 2 LTE cell same band but different bandwith and ARFCN

[nhake]

Hi all

Suppose we have 2 LTE E// cell with same band( FDD 1800 MHz for example): cell A: bandwidth 15MHz, EARFCN1 and Cell B: bandwidth 10MHz, EARFCN2; EARFCN1 <>EARFCN2.
when UE handover from cell A to Cell B, what type of handover in this case: intra-freq handover or inter-freq handover?
what is the disadvantage of this configuration?

Thank you

it's interfrequency HO.
is there interference b/w two cell??

It is considered as Inter-freq HO as the two ARFCNs are different.

It will be considered as Intra-Freq HO , if ARFCN are same even if channel Bandwidth is different.
