Multi-destination control message for integrated access and backhaul nodes

Abstract

Various communication systems may benefit from improved signaling of control messages. For example, certain embodiments may benefit from an improved signaling of control messages in 5G or New Radio systems between a donor node and a plurality of integrated access and backhaul nodes. A method may include generating at a network node a control message for a plurality of other nodes. The method may also include transmitting the control message from the network node to the plurality of other nodes via a multicast radio bearer. The multicast radio bearer may connect the plurality of other nodes.

Dependencies are inferred from the claim text.
