1. An apparatus for wireless communication by an integrated access and backhaul (IAB)-node, comprising:
a memory comprising instructions and one or more processors configured, individually or in any combination, to execute the instructions and cause the apparatus to:
establish a first signaling connection with a first IAB-donor;
establish a second signaling connection with a second IAB-donor, wherein the IAB-node is connected to both the first IAB-donor and the second IAB-donor; and
transmit an indication to the second IAB-donor, after establishing the second signaling connection with the second IAB-donor, that the IAB-node has the first signaling connection to the first IAB-donor.
