Radio network node and method therein, for communication in a wireless communication system. The radio network node comprises: a plurality of antenna elements, a plurality of transceivers, wherein the plurality of transceivers comprise a first subset of the plurality of transceivers coupled to a first subset of the plurality of antenna elements and a second subset of the plurality of transceivers coupled to a second subset of the plurality of antenna elements; and a controller configured to adjust the first subset of the transceivers to work at a first frequency band, and to adjust the second subset of the transceivers to work at a second frequency band.

Method and node in a wireless communication network

Radio network node and method therein, for communication in a wireless communication system. The radio network node comprises: a plurality of antenna elements, forming an antenna array; a plurality of transceivers, each transceiver coupled to at least one dedicated antenna element of the antenna array; and a controller configured to adjust a first subset of the transceivers to work at a first frequency band, and to adjust a second subset of the transceivers to work at a second frequency band. The first subset of transceivers and the second subset of transceivers (are disjoint and configured to operate at their respective frequency bands simultaneously.
