Title: A FIRST NETWORK NODE, A SECOND NETWORK NODE, A THIRD NETWORK NODE, AND METHODS THEREIN FOR ESTABLISHMENT OF A NEIGHBOUR RELATION
Abstract:
A first network node 104 and a method therein for establishing a neighbour relation with a second network node 106,106'. The first network node 104 and the second network node are operating in a wireless communications network 100, The first network node receives an uplink synchronisation signal from a communications device 110 operating in the wireless communications network. For neighbour node determination, the first network node transmits, to a third network node 108 operating in the wireless communications network, a first information, which first information relates to the identity of the received signal and to a first reception time of the signal. The first network node establishes a neighbour relation with at least one of a second network node and one or more of one or more further second network nodes based on a neighbour node determination performed by the third network node based on the first information.
