1. A method comprising:
aligning, with a radio access network node wirelessly connected to at least two parent nodes and to a child node, an uplink reception timing associated with the child node with a downlink reception timing associated with a parent node of the at least two parent nodes;
maintaining, with the radio access network node, a single downlink reception timing associated with the at least two parent nodes;
indicating, with the radio access network node, to each parent node of the at least two parent nodes whether the parent node is a reference parent node or a secondary parent node; and
indicating, with the radio access network node, the secondary parent node about timing transitions compared to the reference parent node and about a downlink reception timing difference to enable the secondary parent node to derive timing gaps at the radio access network node to guarantee the single downlink reception timing at the radio access network node.
