A method performed by a wireless device for reporting an RSTD value to a network node of a wireless communication network. The method includes receiving a configuration of positioning reference signals (PRSs) from the network node, the configuration indicating a plurality of PRS identities for respective transmission points (TPs) of the wireless communication network, determining an RSTD value for a TP based on the received configuration, and reporting the determined RSTD value for the TP to the network node. A first frequency reuse factor for the PRSs that is lower than a default second frequency reuse factor may be used.
