摘要： A transmitting diversity system for wireless transmission of information to a receiver station comprising antenna means composed of a plurality of antenna groups, and each group consisting of a plurality of antennas; receiving means for receiving feedback information from the receiver station using a feedback channel for intra antenna group control; control means for controlling a phase and/or amplitude of a signal transmitted by the antenna means based on said feedback information; and an open-loop transmission diversity encoder for encoding of the signal to be transmitted to the receiver station by every antenna group. It also relates to a method for transmitting a wireless signal to a receiver station by means of a transmitting diversity system having at least four antennas, the antennas arranged in groups; and to a base station and a mobile station comprising such a transmitting diversity system.

摘要： The invention refers to a mobile radio communication system (1) for downlink transmission and to a method for transmitting a signal (s) across at least two downlink paths (5, 6) of a multiple antenna (3, 4) mobile radio communication system (1). The system (1) comprises: a base station (2) comprising a plurality of antennas (3, 4); at least one mobile user equipment (8); at least two downlink paths (5, 6) across at least two of the antennas (3, 4) for transmitting a signal (s) from the base station (2) to the at least one user equipment (8), each downlink path (5, 6) comprising a complex channel coefficient (h1, h2); and a feedback path (9) for returning information on at least one complex weight (w) from the user equipment (8) to the base station (2), the at least one complex weight (w) being used for multiplying the signal (s) which is transmitted across at least two of the downlink paths (6). In order to enhance the tolerance of the system (1) against transmission errors (11) on the feedback path (9) it is suggested that the antennas (3, 4) of the base station (2) are disposed in such a distance (a) to one another that the channels of the antennas (3, 4) are correlated. It is further suggested that error detection mechanisms for detecting transmission errors (11) are incorporated in the feedback path (9). Further, it is suggested that error correction mechanisms for correcting transmission errors (11) are incorporated in the feedback path (9). Finally, it is suggested that filter mechanisms (19, 20) are incorporated in the user equipment (8) and in the base station (2).

摘要： A method for providing a static beam forming in a wireless communication system using an antenna arrangement of a base station which shapes at least one fixed beams, whereby the antenna arrangement covers at least two cells, each cell being covered by at least two beams. The at least two beams covering a cell use the same scrambling code and the same phase reference, whereby the base station autonomously decides which of the at least two fixed beams covering a cell should service a channel.
