| 摘要 |
The present invention relates to an intermediate node which is arranged to relay information between a donor node and at least one served node, and comprises a served antenna arrangement that communicates by means of at least a first and second electrically steerable antenna radiation lobe. During a first mode of operation, all antenna radiation lobes are directed towards a first donor node. During a second mode of operation, the antenna radiation lobes are directed such that the intermediate node is in contact with both the first donor node and the second donor node. During a third mode of operation, all antenna radiation lobes are directed towards the second donor node. A first polarization is associated with each lobe directed towards the second donor node during the second mode of operation and a second polarization is associated with each lobe directed towards the first donor node during the second mode of operation. |
