Abstract: In an example arrangement, a base station (16) serving a wireless device (14) controls the activation time for transmission by the wireless device (14) of aperiodic or semipersistent Sounding Reference Signals (SRS), but accounts for an activation-time recommendation made by a location server (20) with which the serving base station (16) provides its timing information. The arrangement allows the location server (20), which has a view of the overall timeline, to recommend an activation time while still leaving the serving base station (16) in control of the activation time, which the serving base station (16) shares with the location server (20). In turn, the location server (20) uses the activation time to configure neighboring base stations (16), for example, for coordinated reception of the SRS, for positioning the device (14) via Uplink Observed Time Difference of Arrival (UTDOA) determinations.
