Handover for MIMO radio systems

摘要

In a wireless telecommunication system (1) for transmitting a plurality of streams from a base transmission station (3) comprising a plurality of antennas to a mobile station (2) comprising a plurality of antennas, the base transmission station (3) respectively transmits, by way of a plurality of the antennas, each stream obtained by dividing data to be transmitted. The mobile station (2) respectively receives each stream by utilizing the plurality of antennas. A measurement unit (21) respectively measures a reception quality or received power from each antenna relating to a stream. A changeover unit carries out a handover for each stream according to a measurement result by the measurement unit (21) .
