摘要： The present invention relates to a node (1) in a wireless communication system, the node (1) comprising at least one antenna (2) which is arranged to cover a first sector (3) in a first direction (4) and comprises a number (A) of antenna ports (5, 6, 7, 8), which number (A) is at least four. The antenna ports (5, 6, 7, 8) are connected to a transformation matrix (9) which is arranged for transforming the antenna ports (5, 6, 7, 8) to at least a first set (S1) of virtual antenna ports (10, 11) and a second set (S2) of virtual antenna ports (12, 13), each set (S1, S2) comprising a number (B) of virtual antenna ports (10, 11; 12, 13). The number (B) of virtual antenna ports (10, 11; 12, 13) is less than or equal to half the number (A) of antenna ports (5, 6, 7, 8), but not falling below two. The sets (S1, S2) of virtual antenna ports (10, 11; 12, 13) correspond to virtual antennas which are arranged to cover at least a second sector (14) and a third sector (15) in a corresponding second direction (16) and third direction (17). The present invention also relates to a corresponding method.

摘要： The present invention relates to a wireless communication node (20A) adapted to via feeder ports be connected to antenna ports. It comprises signal handling and estimating means (21A) adapted to collect signals from a mobile station and to generate a plurality of channel estimates, connection combination information holding means (22A) adapted to hold information about all possible feeder port - antenna port connections, processing means (24A) comprising channel modelling means (23A) adapted to provide a channel model for the received signals. If further comprises channel model fitting means (25A) adapted to compare the channel model with the channel estimates for a plurality of permutations obtained by the connection combination information and order identifying means (26A) adapted to identify the feeder port connection order corresponding to the permutation order giving the best fit between channel model and channel estimates, hence allowing identification of the order in which the feeder ports actually are connected to the antenna ports.

摘要： The invention discloses a method for obtaining a thinned antenna array (200) comprising a row of M antenna element positions (1, 2, M) spaced a predefined distance (c/) apart. The array comprises a plurality (1, 2', M) of N antenna elements and M-N empty (M-I ) element positions, and the method is used to determine which M-N of the M positions that should be left empty. The method comprises, for each combination of M-N antenna elements: -Determining the mean square error, MSE, of the antenna's performance in estimating a direction of arrival, DOA, of a signal, and determining a lower boundary for said performance, -Determining a point where the MSE has exceeded the lower boundary by a predefined level, a threshold, -Using the M-N combination which has the lowest threshold as the thinned array antenna (200).
