Radio Network Node, a Base Station and Methods Therein

A method in a radio network node (140) for handling hand over of a user equipment (150) to a target cell. The target cells hares a physical cell identity(PCI) with at least a second cell in a cellular communications network. When the target cells hares the PCI with the at least second cell, the radio network node (140) sends (204) a message to the respective at least two cells requesting to set up a radio link to the user equipment(150) and comprising an indication to measure a characteristic of an up link synchronization and comprising an indication to send a report comprising a result of the indicated measurement to the radio network node (140). The radio network node (140) receives from the at least two cells a respective report, which respective report comprises a result of the indicated up ink measurement. The radio network node (140) selects (209) the target cell for hand over of the user equipment (150), based on the result in the report. Publ.
