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.

The invention relates to a cover () for an electronic device (), which electronic device comprises a substrate () and at least two electronic components (), one of which generates an electromagnetic field around itself, where the cover has a first main surface () that faces towards the electronic device, comprises a material that conducts current, and is designed and arranged in such a way in relation to the electronic components that a cooling medium can pass from the first () to the second () electronic component. The invention is characterized in that, by virtue of its shape and its material content, the cover has been given an increased ability to absorb at least part of the electromagnetic field that is generated by at least one of the electronic components. Part of the increased absorbing ability has been achieved by the first main surface of the cover having a shape that minimizes the number of parallel surfaces between the electronic device and the first main surface. The cover can suitably have a number of conical protrusions protruding in the direction towards the electronic components ().
