Embodiments herein relate to a first radio network node for handling communication of a wireless device in a wireless communication network, wherein the first radio network node provides radio coverage over a first service area using a first reference signal, which first reference signal is for identifying the first service area in the wireless communication network. The first radio network node changes one or more antenna parameters, corresponding to one or more antenna ports used for an active mode transmission for the wireless device, independently of one or more other antenna parameters corresponding to one or more other antenna ports used for an idle mode transmission within the first service area. The first radio network node further uses the one or more antenna ports for active mode transmissions for the wireless device and/or the one or more other antenna ports for idle mode transmissions within the first service area.
