1. A method for wireless communication at a first integrated access and backhaul (IAB) node, comprising:
transmitting, by the first IAB node on a signaling connection with an IAB donor node, a separate connection with the IAB donor node, or a separate connection with a network device separate from the IAB donor node, an indication that the first IAB node supports sidelink communications;
establishing, by the first IAB node and based at least in part on the transmitted indication that the first IAB node supports the sidelink communications, the signaling connection with the IAB donor node and a sidelink connection with a second IAB node or a user equipment (UE), wherein the first IAB node comprises a mobile termination unit and a distributed unit, and supports the sidelink communications;
transmitting a first one or more data messages to the IAB donor node via the established signaling connection; and
transmitting a second one or more data messages to the second IAB node or the UE via the established sidelink connection.
