摘要： In mobile communications systems transmission antenna diversity is used e.g. to compensate for fading caused to the signal on the radio path. It is known to make the choice of transmission antenna jointly for all subscriber connections, but it is not hereby possible to offer the optimum transmission antenna to simultaneous connections. The present invention aims at a method for implementing transmission antenna diversity on a data transmission connection, which is set up between a transmitting unit (BS), wherein there are several transmission antenna routes (ANT1, ANT2, ANT3), and a receiving unit (MS1, MS2). In the method, a broadcast signal is transmitted through all transmission antenna routes (ANT1, ANT2, ANT3) of the transmitting unit, with the aid of these signals a choice is made in the receiving unit (MS1, MS2) of the optimum transmission antenna route and a message of the choice is transmitted to the transmitting unit (BS), which transmits user data through the transmission antenna route connected for use. According to the invention, the method is characterised in that the broadcast signal of each transmission antenna route is shaped by an individual signal shaping method which is different from the others and a transmission antenna route is connected for use based on the received antenna choice message, individually for each receiving unit.

摘要： The invention relates to a method for controlling the weighting of a data signal in the at least two antenna elements of a first radio connection unit of a radio communications system, which data signal is to be distributed for parallel transmission to a second radio connection unit to at least two beams. In order to improve such a method, it comprises: determining in the second radio connection unit a weight information enabling the first radio connection unit to determine the sets of weights for suitable beams for transmission and transmitting it to the first radio connection unit; and distributing the data signal in the first radio connection unit to those sets of weights and transmitting the data signals simultaneously via the formed beams. Alternatively or additionally, the second unit determines the number of beams to be used and informs the first unit about it. The invention equally relates to corresponding radio connection units, radio connection unit modules and radio communications systems.
