Abstract
The present invention relates to a node () in a wireless communication system, the node () comprising at least a first and second antenna function (), and a first and second radio chain (). At least at the start of a first mode of operation, each antenna function () is connected to a corresponding radio chain (). The node further comprises a switching network () and a beamforming network (), which switching network (), at least at the start of a second mode of operation, is arranged to disconnect at least one antenna function () from its corresponding radio chain () and connect it to another of the radio chains () via at least a part of the beamforming network (), such that at least two antenna functions () are connected to the same radio chain (). The node () is arranged to perform beamforming for said at least two antenna functions () by means of said beamforming network (), the switching network () being arranged to switch between the first mode and the second mode.
