RRC signaling based BWP switch in case of TDD system query

Hi guys, one question.
For RRC signaling based BWP switch in case of TDD system, if I mention just DL BWP ID, then UL BWP will also changed automatically, as TDD is unpaired system?
Is this the correct understanding?

Yes, BWP in TDD for both UL and DL will be changed simultaneously.
Actually, both should have the same BWP-ID.
