1. A method at a wireless device, comprising:
providing one or more group delay parameters for the wireless device to a positioning entity,
wherein the one or more group delay parameters comprise a round-trip-time (RTT) type parameter indicating whether RTTs reported by the wireless device are measured RTTs or actual RTTs, and
wherein it is determined that a group delay of the wireless device is included in the reported RTTs when the RTT type parameter indicates that the reported RTTs are measured RTTs.
