Problems solved by technology
Physical verification of cabling is also difficult and time consuming given that antennas are often located in tall masts
Ensuring that the connection is made correctly is extremely difficult, and handling connection errors is complicated by the difficulty of identifying how the cable is actually connected or what the error is

Embodiment Construction
[0019] figure 1 is a block diagram of an arrangement 100 in which a wireless communication node 20A is connected to an antenna part 10A with a plurality of antenna elements 1A, 2A, 3A, 4A, here of the same polarization. It should be understood that the invention is not limited to order recognition when there are four antenna elements, this is only a specific example, there can be slightly fewer antenna elements and many more antenna elements, especially since more antenna elements, the invention The problems to be solved tend to become more complex and serious. Each antenna element is connected to an antenna port AP; 11A 1 , 11A 2 , 11A 3 , 11A 4 . Antenna elements 1A, 2A, 3A, 4A by means of feeder cables 12 21 、12 13 、12 34 、12 42 Connect to feeder port FP21A 1 , 21A 2 , 21A 3 , 21A 4 . In this case, the current connection combination is as follows: Feeder port 21A 1 Connected to antenna port 11A 2 , feeder port 21A 2 Connected to antenna port 11A 4 , feeder...

The present invention relates to a wireless communication node (20A) connected to an antenna part (10A) with a plurality of antenna elements (1A, 2A, 3A, 4A) and antenna ports (11A1, 11A2, 11A3, 11A4) over feeder ports (21A1, 21A2, 21A3, 21A4). It comprises signal analyzing means (21A) adapted to analyze a signal received from a mobile station, and to, for each pair of antenna elements (1A, 2A, 3A, 4A), calculate the respective phase difference or phase angle between the signals from the elements of the pair, phase progression function handling means (26A) for calculating a phase progression function over the antenna ports, connection combination handling means (24A) adapted to find all possible combinations of connections between the antenna ports and the feeder ports and the corresponding phase angles or phase differences. It further comprises ordering means (25A) adapted to order said phase angles / phase differences, and fitting and error detecting means adapted (27A) to fit the ordered phase angles / differences to the phase progression function to find the errors between the ordered, calculated phase differences or phase angles corresponding to each connection combination and the phase progression function and to identify the connection combination for which the error of the fit is lowest.
Description
technical field [0001] The invention relates to a wireless communication node adapted to be connected to or comprising an antenna part with a plurality of antenna elements with a corresponding antenna port to which a feeder port of the communication node is connected. Antenna ports are associated with unique antenna port identifications, and feeder ports are associated with corresponding unique feeder port identifications. The invention also relates to a method in such a node for determining which feeder ports are actually connected to which antenna ports. Background technique [0002] For antenna arrangements comprising multiple antenna elements, eg array antenna systems, it is often important to know which antenna ports are actually connected to which feeder ports, ie to which radio chains. This means not only how they should be connected, but how they are already connected. It is also important that they are connected in a specific desired way, which means that exactly ...
