Abstract

Network nodes (102, 104), control node (100) and methods therein, for enabling establishment of a neighbor relation between a first network node (102) and a second network node (104) in a wireless network. The control node (100) sends (1:1) or distributes, to network nodes in the network including the first network node (702), a set of reference signals reserved for neighbor relation establishment. The second network node (104) transmits (1:3) one of the reserved reference signals which is then detected by a wireless device (D1) being served by the first network node (102) which then receives (1:4), from the wireless device (D1), a measurement report indicating the detected reference signal that is recognized by the first network node (102) as belonging to the set of reserved reference signals. The first network node (102) can then identify (1:5) the second network node (104), based on the reserved reference signal in the measurement report, and establishes (1:6) a neighbor relation with the identified second network node (104).
