Abstract
Embodiments herein relate to a method performed by a first communication node (110; 121) for determining the position of a second communication node (122) in a wireless communications network (100). The first communication node (110; 121) transmits a timing measurement message to the second communication node (122) as a beamformed transmission based on channel sounding feedback information received from the second communication node (122). The first communication node (110; 121) also receives an acknowledgement message from the second communication node (122) for the timing measurement message in the beamformed transmission. Furthermore, the first communication node (110; 121) determines the position of the second communication node (122) at least partly based on a transmission time of the timing measurement message and a reception time of the acknowledgement message. Embodiments of the first communication node (110; 121) are also described. Embodiments herein also relate to a second communication node (122) for enabling positioning of the second communication node (122) in a first communication node (110; 121) in a wireless communications network (100) and a method therein.
