Methods, systems, and devices for wireless communications are described. Some wireless communications systems may implement an integrated access and backhaul (IAB) network architecture where relay nodes connect with other IAB nodes via wireless backhaul links. For improved node discovery, during or after an initial relay integration procedure with a parent node, a relay node may transmit a capability report to the parent node indicating a duplexing capability of the relay node (e.g., whether the relay node is half-duplex or full-duplex capable). Based on the duplexing capability, the parent node may determine discovery reference signal (DRS) transmission and measurement resources for the relay node and configure the relay node with these resources. The relay node may use these resources for transmitting DRSs and monitoring for DRSs from other IAB nodes. If the relay node discovers another IAB node in the network, the nodes may form a wireless backhaul link.
