Methods and apparatus for determining an assistance data transmission time to account for cell timing acquisition are disclosed. In an example method, a network node determines whether a target wireless communication node (110) will need to obtain timing information for at least one cell to be included in the assistance data. The network node then estimates an acquisition time &Dgr;T for the wireless communication node (110) to obtain timing information for at least a first cell. The network node then transmits the positioning assistance data to the wireless communication node (110) at least &Dgr;T before an expected time for the wireless communication node (110) to begin performing positioning measurements. In some embodiments, the network node is configured to wait for a time period at least equal to an expected reporting delay that accounts for the acquisition time &Dgr;T, before deciding that the positioning has failed.
