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.

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： The determination of the direction of arrival of a radio signal by an antenna array connected to a base station of a radiocommunications system, particularly of an SDMA (Space Division Multiple Access) mobile radio system, is complicated by multipath. A method is known which uses the so-called ESPRIT algorithm and which is especially suited for a reliable estimation of direction, since the receive level (Sm) and the phase position (.phi.m) are measured for each radiating element and entered in a symmetrical matrix (A) in order to then determine the direction of arrival by eigenvalue decomposition.A simpler and faster method (100) is proposed which involves computing the eigenvector (Wn) corresponding to the dominant eigenvalue (.lambda.1) of this matrix (A), which indicates the direction of arrival (DOA) of the strongest radio signal (S) (steps 130 and 140). The computationally intensive eigenvalue decomposition is eliminated.
