Embodiments herein relate, in some examples, to a method performed by a wireless device (10) for handling communication of the wireless device (10) in a multicarrier operation in a wireless communication network (1), wherein the wireless device (10) is configured with a discontinuous reception cycle and is served by a first serving cell and is served or expected to be served by a secondary serving cell. The secondary serving cell is provided on a lean carrier wherein reference signals are transmitted with a bandwidth that is variable between a first bandwidth and a second bandwidth, wherein the second bandwidth is narrower than the first bandwidth. The wireless device receives on the secondary serving cell, one or more reference signals assumed by the wireless device (10) to have been transmitted on the secondary serving cell over the second bandwidth. The wireless device (10) receives, on the first serving cell, a secondary cell setup command for the secondary serving cell, which secondary cell setup command indicates a state transition of the secondary serving cell for the wireless device (10). The wireless device (10) further receives, upon reception of the secondary cell setup command, on the secondary serving cell, one or more reference signals assumed by the wireless device (10) to have been transmitted on the secondary serving cell over the first bandwidth.
