Abstract
A method is implemented by a node in a wireless communication system (10). The method includes obtaining (110) the results of one or more first radio measurements performed on one or more first radio signals transmitted or received by geographically separated transmission points, TPs, (20) of a shared cell. The method also includes determining (120), using the obtained results and from among the TPs (20) that transmit second radio signals based on the same cell identity, the particular TP (20) that transmits the second radio signal on which a positioning measurement is performed for determining a target wireless communication device's position. The method finally entails using (130) information related to the determined TP (20) to perform one or more positioning tasks.

A method, implemented by a node in a wireless communication system, the method comprising:
- obtaining results of one or more first radio measurements performed 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, a 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.
A method, implemented by a wireless communication device in a wireless communication system, the method comprising:
- performing a positioning measurement on one of multiple radio signals that geographically separated transmission points (TPs) of a shared cell transmit based on the same cell identity;
- determining a particular TP that transmits the radio signal on which the wireless communication device performs the positioning measurement;
- and
- associating an identity of the particular TP and the same cell identity with an identity of the wireless communication device and/or a result of the positioning measurement.
A method, implemented by a node in a wireless communication system, the method comprising:
- determining that a positioning measurement for determining the position of a target wireless communication device has been or is to be performed in a shared cell on one of multiple second radio signals that geographically separated transmission points (TPs) of the shared cell transmit based on the same cell identity;
- and
- responsive to the determination, triggering a procedure that uses the results of one or more first radio measurements to determine the particular TP that transmits the second radio signal on which the positioning measurement has been or is to be performed, the one or more first radio measurements performed on one or more first radio signals transmitted or received by the TPs.
