The method comprises time stamping a data packet to be transmitted from the first node to the second node with a first time stamp, transmitting said data packet to the second node, receiving the transmitted data packet back from the second node, repeating the transmitting and receiving step at least one more time, time stamping the last received data packet from the second node with a second time stamp, and calculating the distance between the first and second node based on the first and second time stamp, the number of repetitions of the repeating step and the internal delays in the first and second node.

Abstract: A method performed by a secondary node for enabling positioning of a device in a wireless communications network. First, the secondary node receives a positioning data packet from a primary node to the device. The secondary node then determines the transmitting time of the positioning data packet based on the reception time of the positioning data packet in the secondary node and the position of the primary node and the secondary node. The secondary node also receives a request response from the device to the primary node. The secondary node then enables positioning of the device based on the determined transmitting time of the positioning data packet and the reception time of the received request response. A secondary node for enabling positioning of a device in a wireless communications network is also provided. Furthermore, a central node and a method therein for positioning a device in a wireless communications network are also provided.
