Abstract
Additional information is included in or used to generate a positioning reference signal to enable detection of a cell identifier “collision” between two different cells associated with two or more base stations. In one example embodiment, a user equipment terminal detects the collision using the additional information included in or used to generate positioning reference signals sent by two or more base stations and reports the collision to the network, and the network resolves the collision by assigning a different cell identifier to one of the colliding cells.
