Abstract

A method performed by a wireless device for handling two or more beamformed communication links initialized with one or more network nodes in a wireless communications network is provided. The wireless device determines at least one compatibility state for the two or more beamformed communication links based on one or more current radio signal characteristics at the wireless device for the two or more beamformed communication links, wherein the at least one compatibility state indicates if the wireless device currently is able to simultaneously receive transmission beams of the two or more beamformed communication links or not. The wireless device transmits information indicating the at least one determined compatibility state for the two or more beamformed communication links to at least one of the one or more network nodes. A wireless device as well as a network node and method of operation thereof are also disclosed.
