1. A method performed by a user equipment, UE, in a wireless communication network, the UE being configured with at least a first UE-specific radio resource control configured bandwidth part, BWP, of a secondary serving cell, Scell, of the UE, the method comprising:
receiving at least a second BWP configuration associated with a BWP of the Scell of the UE;
determining whether the first or the second BWP is a dormant BWP based on a received higher layer parameter in an Scell configuration that indicates a BWP identifier of the at least first or second BWP as the dormant BWP, wherein the Scell configuration comprises a dormant BWP; Id field as part of ServingCellConfig information to indicate the BWP that is the dormant BWP; and
receiving a message from a network node operating in the wireless communication network, the message comprising an indicator that data is not scheduled and causing the UE to switch from the first or second BWP identified as the dormant BWP to the other of the first or second BWP.
