In one aspect of the teachings herein, a wireless communication network includes two or more radio transmission points sharing the same Physical Cell Identity, PCI, and the network provides a User Equipment, UE, with positioning assistance data indicating the muting patterns used by respective ones of the transmission points for transmitting Positioning Reference Signals, PRS. The respective transmission points sharing the same PCI both transmit PRS identified by the shared PCI, but the transmissions are differentiated as a consequence of the respective muting patterns. Correspondingly, the UE exploits the positioning assistance data from the network, to make PRS measurements that are differentiated with respect to the transmission points sharing the same PCI. Differentiating between PRS as received from the different transmission points sharing the same PCI yields more accurate positioning, whether the positioning is done by the UE, or by the network based on receiving measurements from the UE. |
