Method and apparatus for transmitting data in a hierarchical wireless network

Disclosed are a method and apparatus for transmitting data in a hierarchical radio network (1) described in the data on node (2) of the radio network (1) are transmitted to a central node (3) and / or data (from a central node 3) are transmitted to one or more nodes (2) and which is constructed in a tree topology with the central node (3) as a root, wherein each node (2, 3) has a unique node number (K), exactly one time slot (Z) for transmitting data in the radio network (1) and a parent account (2, 3) are zugwiesen and wherein the timeslots (Z) of the node (2, 3) are combined in a time slot block. It is contemplated that the node numbers (K) is selected such that each node (2) has a higher node number (K) as its parent node (2, 3), and that the assignment of the node number (K) to a time slot (Z is carried out) depending (in the time slot block by the communication direction through the hierarchy levels H) of the radio network (1) such that in the uplink direction of communication from the central node (3) to one or (more nodes 3) a node (2) having a higher node number (K ) is associated with a subsequently arranged in the time slot block time slot (Z) and that in the downlink communication from a node (2) to the hub (3) a node (2, 3) with a lower node number (K) arranged one later in the time slot block is assigned to time slot (Z).
