Abstract
A method is provided for transmitting information in a radio communication system provided with at least one transmitting station (AP) and at least two receiver stations (MT). The transmitting station (AP) and the receiver stations (MT) are connected together via a radio communication interface. The transmitting stations (AP) includes a transmitting antenna with K<SB>B</SB>31 antenna elements, whereby K<SB>B</SB>≧1, and the receiving stations (MT) respectively include a transmitting antenna with K<SB>M</SB> antenna elements, whereby K<SB>M</SB>≧1, and which communicate via a MIMO-transmission. The transmitting signals transmitted from the antenna elements of the transmitting antenna of the transmitting station (AP) are produced in a common process and are adapted in relation to the transmitting energy to be used during radiation. Receiving signals received by the antenna elements of the receiver antenna of the receiver stations (MT) are detected in a linear signal process.

8. A method of transmitting information in a radio communication system with at least one transmit station and at least two receiver stations, the method comprising:
-
connecting the transmit station and the receiver stations to each other via a radio communication interface;
providing that the transmit station include a transmit antenna with KB antenna elements with KB≧
2 and providing that each of the receiver stations include a transmit antenna with KM antenna elements with KM≧
2, wherein the transmit station and the receiver stations communicate using MIMO transmission;
generating transmit signals radiated from the antenna elements of the transmit antenna of the transmit station in a common process and matching the transmit signals as regards a transmit energy to be used for radiation; and
detecting received signals received by the antenna elements of the receive antennas of the receiver stations in a linear signal processing through demodulation, taking into account space and time transmission characteristics between the transmit station and the respective receiver station. - View Dependent Claims (9, 10, 11, 12, 13)
