<p>The invention provides a method of locating a mobile station in a wireless indoors communication system, the wireless indoors communication system further comprising a plurality of remote radio headends coupled to a base station, a mobile station being coupled to at least a first remote radio headend of the plurality of remote radio headends, the plurality of remote radio headends being adapted for expanding wireless coverage of the base station, the method comprising the steps of: sending a sounding signal request from the base station to the mobile station; receiving the sounding signal request by the mobile station and sending a sounding signal from the mobile station to the first remote radio headend; and receiving the sounding signal by the first remote radio headend and obtaining an stamped sounding signal by multiplying the sounding signal with a first filter. The method further comprises: sending the stamped sounding signal by the remote radio headend to the base station; receiving the stamped sounding signal by the base station and comparing the stamped sounding signal with a database, the database comprising a list of the plurality of remote radio headends with an assigned unique transfer function for each remote radio headend and a location of the first remote radio headend within an indoors infrastructure; and identifying the first remote radio headend communicating with the first mobile station, the identification including an approximate location of the mobile station.</p> |
