Abstract
An Integrated Access and Backhaul (JAB) node incorporates two functions, a so-called “base station” function and a so-called “mobile terminal” function. In order to limit the interferences between base stations, all IAB nodes in the same network must be synchronised with one another. In order to ensure this synchronisation, each IAB node may use a time shift value transmitted by its parent node. However, since an IAB architecture is an arborescent architecture, errors in measuring an estimated time shift value for a given IAB node have repercussions on the measurements of estimated time shift values for its child node and so on. Accordingly, the “base station” function of a child IAB node is not activated as long as a time shift value determined by its parent node does not meet a synchronisation criterion.
