1. An apparatus comprising at least one processor and at least one memory including computer program code, the at least one memory and the computer program code configured to, with the at least one processor, cause the apparatus at least to perform:
establishing a communication link between a first one of a plurality of relay nodes and at least a second one of the plurality of relay nodes, which are in synchronous movement,
receiving beam management assistance information from the first one of the plurality of relay nodes at the at least second one of the plurality of relay nodes upon an occurrence of beam failure at the first one of the plurality of relay nodes,
deciding, at the at least second one of the plurality of relay nodes, about a timing at which the received beam management assistance information is to be transmitted to a serving network node, and
transmitting the received beam management assistance information from the at least second one of the plurality of relay nodes to the serving network node at the decided timing.
