Claim of US Patent No. 10,694,543

1. A method performed by a radio network node operating in a wireless communications network, wherein the method comprises:transmitting information to a further network node identifying a random access preamble received at the radio network node and indicating a first reception time; and
establishing a neighbor relation with another radio network node in the wireless communications network, responsive to receiving an indication that the other radio network node neighbors the radio network node, the indication based on the further network node determining that the other radio network node received the same random access preamble at a second reception time, wherein a difference between the first reception time and the second reception time is within a desired threshold value and the difference corresponds to different distances of propagation paths from a communication device to the radio network node and to the other network node.
