Method and a system for configuring a beam forming antenna in a communication network

摘要

A method of configuring a beam forming antenna in a communication network that comprises a first node where the beam forming antenna is located, second nodes and at least one destination node, communication links being established between said first node and said at least one destination node through at least some of said second nodes. The method comprises: emitting a signal by the beam forming antenna configured with a first set of antenna parameters; the same signal being sent from the first node to several second nodes; obtaining, for a plurality of communication links through which the signal has been sent, at least one physical magnitude representing the distortion caused by each communication link to the signal; aggregating said physical magnitudes of said plurality of communication links; and obtaining a second set of antenna parameters for configuring the beam forming antenna in accordance with said aggregated physical magnitudes.

1. A method of configuring a beam forming antenna in a communication network that comprises a first node where the beam forming antenna is located, a plurality of second nodes and at least one destination node, communication links being established between said first node and said at least one destination node through at least some of said second nodes, characterized in that the method comprises:
obtaining a first set of antenna parameters so that the beam forming antenna configured with said first set of antenna parameters is prevented from emitting beams in directions other than towards the plurality of second nodes to which the signal is to be sent, emitting a signal by the beam forming antenna configured with the first set of antenna parameters, the signal being sent from the first node to several second nodes, obtaining, for a plurality of communication links through which the signal has been sent, at least one item of information representing distortion caused by each communication link to the signal, obtaining for each link of said plurality of communication links information representing energy received through said link, the at least one item of information and said information being two types of information characterizing each link of said plurality of communication links, aggregating said items of information of said plurality of communication links, obtaining a second set of antenna parameters for configuring the beam forming antenna in accordance with said aggregated items of information; wherein aggregating the items of information of the plurality of communication links and obtaining the second set of antenna parameters are performed by the at least one destination node; and wherein obtaining the second set of antenna parameters for configuration of the beam forming antenna comprises calculation of a vector of the antenna parameters that involves, a sum of information of a first type relating to the at least one item of information obtained for each link of said plurality of communication links established on the various paths, divided by a sum of information of a second type representing energy received through each link of said plurality of communication links.
