The invention relates to a system and method for facilitating position determination through beamforming of positioning reference signals. Techniques are provided for positioning a mobile device in a wireless network using directional positioning reference signals, PRS, also referred to as PRS beamforming. In an example method, a plurality of directional PRSs (SI, S2) are generated for at least one cell of a base station (410) such that each of the plurality of directional PRSs includes at least one signal characteristic and a transmission direction, either or both of the at least one signal characteristic and the transmission direction may be different or unique. The plurality of directional PRSs is transmitted within the at least one cell such that each of the plurality of directional PRSs is transmitted in the transmission direction. A mobile device (420) may acquire and measure at least one of the directional PRSs identifiable using associated signal characteristics. The measurements may be used to assist
