Abstract: Disclosed is a method performed by a position calculation node (160) in a wireless communication network (100). The node (160) is arranged for improving accuracy when determining positions in the wireless communication network.

Abstract: A method in a radio network node for selecting a second SCell of a wireless device. The radio network node sends (201) data to a network node, upon a request to release the wireless device from a first connected state, in which the wireless device is connected to a first PCell and configured with a first SCell. The data indicates the first PCell and the first SCell. The radio network node retrieves (202) the sent data when the wireless device enters a second connected state.
