DETERMINING POSITION OF A WIRELESS DEVICE USING REMOTE RADIO HEAD DEVICES

摘要

It is presented a method for assisting the determining of a position of a wireless device, the method being performed in a network node connected to a plurality of remote radio head devices via a combiner. The method comprises the steps of: receiving an uplink signal via the combiner; comparing a carrier frequency of the uplink signal with a set of manipulation schemes for a carrier frequency of uplink signals, wherein the manipulation schemes are different for at least some of the plurality of remote radio head devices; and providing a proximity indication that the position of the wireless device is in the vicinity of a remote radio head device the frequency manipulation scheme of which best matches the uplink signal. A corresponding network node, computer program, and computer program product are also presented.
