Abstract: Methods, apparatus and systems for address configuration for integrated access and backhaul (IAB) links are disclosed. In one embodiment, a method performed by a first network node is disclosed. The method comprises: obtaining, from an operations administration and maintenance (OAM) or a second network node, a first address information related to at least one Internet Protocol security (IPsec) address; generating, based on the first address information, a second address information; and transmitting, to the second network node, the second address information based on a radio resource control (RRC) message, wherein the first network node and the second network node are connected via a backhaul link in an integrated access and backhaul (IAB) network.

Abstract: Systems, apparatus, and methods of wireless communication are described, and more specifically, to techniques related to traffic transmission schemes for inter-donor redundancy and radio link failure (RLF) scenarios. One example method includes transmitting, from a first network node configured to communicate with a first integrated access and backhaul (IAB) node, to a second network node, a first message including information relating to dual connectivity (DC). The first and second network nodes can each be IAB-donors comprising an IAB-donor central unit (CU) and one or more IAB-donor distributed units (DU).

Abstract: The present disclosure describes methods, systems, and devices for recovering a recovery integrated access backhaul-node (IAB-node) for new radio (NR) from an initial IAB-donor-central unit (CU) to a new IAB-donor-CU and/or configuring a F1 connection between an IAB-node and an IAB-donor-CU. One method includes retrieving, by the new IAB-donor-CU from the initial IAB-donor-CU, context information; and configuring a connection with the recovery IAB-node. Another method includes sending, by the new IAB-donor-CU to the initial IAB-donor-CU, a request for retrieving user equipment (UE) context; and receiving, by the new IAB-donor-CU from the initial IAB-donor-CU, a response for retrieving UE context. Another method includes receiving, by the new IAB-donor-CU from the recovery IAB-DU, a first message to initiate a first F1 procedure; sending, by the new IAB-donor-CU to the recovery IAB-DU, a second message to indicate whether the first F1 procedure is successful.
