Abstract: An apparatus, method and computer program is described comprising: sampling a positioning reference signal received at a user device of a mobile communication system from a communication node of the mobile communication system, wherein the received positioning reference signal is a multipath signal having a line of sight component; processing the sampled received positioning reference signal with the positioning reference signal as transmitted by the communication node; identifying, based on said processing, signal paths from the communication node to the user device relative to an angle of departure of the positioning reference signal; and generating a model to estimate at least one of an orientation of the user device and a gain of the one or more identified signal paths of the multipath signal.
