A method implemented by a node in a wireless communication system, the method characterized by: obtaining the results of one or more first radio measurements performed respectively on one or more first radio signals transmitted or received by geographically separated transmission points, TPs, of a shared cell; determining, using the obtained results and from among the TPs that transmit second radio signals based on the same cell identity, the particular TP that transmits the second radio signal on which a positioning measurement is performed for determining a target wireless communication device's position; and using information related to the determined TP to perform one or more positioning tasks; wherein said determining comprises: comparing the results of the first radio measurements to one another, determining based on said comparison the maximum, or alternatively the minimum, one of the results, and identifying said particular TP as the TP that transmitted or received the first radio signal on which the first radio measurement with said maximum or minimum result was performed; and the method further comprising obtaining a result of the positioning measurement, and wherein said determining comprises determining which of the first radio measurements has a result that best matches with the result of the positioning measurement according to one or more defined criterions, and identifying the particular TP as the TP that transmitted or received the first radio signal on which the respective determined first radio measurement was performed. obtaining the results of one or more first radio measurements performed respectively on one or more first radio signals transmitted or received by geographically separated transmission points, TPs, of a shared cell; determining, using the obtained results and from among the TPs that transmit second radio signals based on the same cell identity, the particular TP that transmits the second radio signal on which a positioning measurement is performed for determining a target wireless communication device's position; and using information related to the determined TP to perform one or more positioning tasks; wherein said determining comprises: comparing the results of the first radio measurements to one another, determining based on said comparison the maximum, or alternatively the minimum, one of the results, and identifying said particular TP as the TP that transmitted or received the first radio signal on which the first radio measurement with said maximum or minimum result was performed; and comparing the results of the first radio measurements to one another, determining based on said comparison the maximum, or alternatively the minimum, one of the results, and identifying said particular TP as the TP that transmitted or received the first radio signal on which the first radio measurement with said maximum or minimum result was performed; and the method further comprising obtaining a result of the positioning measurement, and wherein said determining comprises determining which of the first radio measurements has a result that best matches with the result of the positioning measurement according to one or more defined criterions, and identifying the particular TP as the TP that transmitted or received the first radio signal on which the respective determined first radio measurement was performed.
