Abstract: Methods, systems, and devices for wireless communications are described. In an integrated access and backhaul (IAB) network, a wireless node may receive an indication of a conditional handover configuration from a relay node. The conditional handover procedure may specify a set of trigger conditions for a conditional handover procedure supported by the relay node. The indication of the conditional handover may indicate a change of the cell from a first cell identifier to a second cell identifier. The wireless node may determine that a trigger condition of the set of trigger conditions is satisfied. The wireless node may then transmit, to the relay node, a random access message to initiate the conditional handover procedure for the cell from the first cell identifier to the second cell identifier.
