1. A donor integrated access backhaul, IAB, node configured with a distributed unit, DU, for communicating with a wireless device and configured with a central unit, CU, for communicating with at least a first child IAB node, the donor IAB node comprising:
processing circuitry configured to:
indicate a determined first synchronization signaling blocks, SSB, transmission configuration, STC, for the at least first child IAB node, to the at least first child IAB node, the first STC being associated with inter-node measurement;
receive, from an operation, administration and management, OAM, unit, an indication of a second STC that has been preconfigured, the second STC being different from the first STC; and
reconfigure the first child IAB node from the second STC to the first STC by causing the second STC to be overwritten with the first STC, the reconfiguration of the first child IAB node including managing time patterns for the first child IAB node.
