Methods and device for use in a wireless device of reporting positioning measurements comprises receiving network assistance information from a network node. The network assistance information is for assisting the wireless device in performing Observed Time Difference Of Arrival (OTDOA), and comprises: a list of reference cells; a list of neighbor cells; and a rule for terminating Reference Signal Time Difference (RSTD) measurements. The method further comprises performing RSTD measurement between a cell in the reference cell list and a cell in the neighbor cell list. Upon determining the RSTD measurement satisfies the rule for terminating RSTD measurements, the method includes reporting the RSTD measurements to the network node. Upon determining the RSTD measurement does not satisfy the rule for terminating RSTD measurements, performing another RSTD measurement between the cell in the reference cell list and a cell in the neighbor cell list.
