    摘要： Embodiments herein relate to a method performed by a wireless device (10) for managing beam-formed communication in a wireless communication network (1), wherein the wireless device (10) is configured to handle separate directional device beams at the wireless device (10). The wireless device (10) forms an active set for a first device beam out of the separate directional device beams of the wireless device by selecting one or more first network beams out of a plurality of separate directional network beams of the wireless communication network (1). The one or more first network beams are selected based on received signal strength or quality, and the active set is to be used for transmission or reception of data. The wireless device selects a first network beam in the active set as a preferred network beam for transmission or reception of data. The wireless device further forms a monitored set for a second device beam out of the one or more separate directional device beams of the wireless device by selecting one or more second network beams out of the plurality of separate directional network beams of the wireless communication network (1). The one or more second network beams are selected based on received signal strength or quality, but are not to be currently used for the transmission or reception of data. The wireless device transmits to a network node (12) a first indication of the preferred network beam and the received signal strengths or qualities for the one or more first network beams in the formed active set for the first device beam of the wireless device, and a second indication indicating the one or more second network beams of the formed monitored set and the received signal strengths or qualities for the one or more second network beams in the formed monitored set for the second device beam of the wireless device.
