1. A mobile device for a wireless communication network, the mobile device comprising
an antenna; and
a transceiver,
wherein the transceiver is configured to
transmit a first signal via the antenna, the first signal comprising a unique identification of the mobile device and a request to transmit to the mobile device information for estimating a position of the mobile device, and
following the transmission of the first signal, receive a second signal via the antenna, the second signal comprising the information for estimating a position of the mobile device, the information for estimating a position of the mobile device comprising a first information about a spatial direction of a position reference signal (PRS) sent out by a base station of the wireless communication network and a second information indicative of a location of the base station, and
wherein the signal processor is configured to estimate a position of the mobile device using the spatial direction of the position reference signal (PRS) and the location information included in the second signal.
