Abstract
A method for identifying a remote radio unit in a communication system comprises a plurality of remote radio units communicating with a central unit and pattern providing means for providing information about dedicated gain change patterns of the remote radio units. The method comprises receiving a signal from a station by a remote radio unit of the plurality of remote radio units. The method also includes changing the gain of at least one remote radio unit according to a dedicated gain change pattern of the at least one remote radio unit. The method also includes detecting a gain change pattern for the received signal and identifying the remote radio unit by comparing the detected gain change pattern with information about dedicated gain change patterns of the remote radio units provided by the pattern providing means. An example may be locating a station, such as a user equipment, in a distributed radio system.
