ABSTRACT:
The invention relates to a method for performing positioning in a radio system. At least two different antenna elements of an array antenna of a base station transmit mutually non-interfering identifier signals that are received by a terminal that generates a spatial signature of the received signals. Either the terminal or the network part of the radio system defines the location of a transmitter or receiver by means of the spatial signature of the signals.
