A method performed by a user equipment, UE, in a wireless communication network is provided. The method includes receiving a bandwidth part, BWP, configuration associated with a BWP of a secondary serving cell, Scell, of the UE. The UE determines whether the BWP of the Scell of the UE is a dormant BWP based on a received higher layer parameter in a Scell configuration that indicates an identifier of the dormant BWP. In response to determining whether the BWP of the Scell is a dormant BWP, the UE determines a set of actions performable by the UE based on whether the BWP is a dormant BWP; and performs the set of actions.
