Multi-antenna transmission method for providing downlink
radio coverage from a
radio base station to a mobile terminal in a mobile communications network by means of a
transmission system, comprising: - at least one multi-radiator transmitting antenna directed towards at least one
mobile device, in particular a
smart antenna or an array antenna, - at least one
database that is associated with at least one coverage
cell of the mobile communications network and contains information about the position of the
mobile device; - Method means that interact with the at least one multi-radiator transmission antenna and the at least one
database, wherein the method means are configured to connect a transmission direction with the position of the
mobile device, wherein the transmission direction is suitable for reaching the mobile device, comprise the steps: a) Detecting the position of the mobile device; b) Storing the position in at least one
database; c) Determining at least one transmission direction of at least one transmission beam from the at least one multiple-radiator transmission antenna to the mobile device, depending on the position stored in the at least one database, wherein at least one of the transmission parameters, which must be determined in order to transmit in the transmission direction in the at least one multiple-radiator transmission antenna, is linked to the stored position of the mobile device, and d) Comparing reception
quality information signaled by the mobile device with the reception quality expected for the position achieved by the mobile device and stored in the database.
