F1 connection options in integrated access and backhaul handover scenarios

A core network node for wireless communication, comprising:

• a memory;
• and
• at least one processor coupled to the memory, wherein the core network node is configured to:
• receive, from a first network node, control information indicative that the core network node is to forward one or more containers of an integrated access and backhaul (IAB) node-to-central unit connection of an IAB node, wherein the control information includes a first identifier associated with the IAB node and a second identifier associated with a second network node;
• transmit the one or more containers to the second network node based on the second identifier being included in the control information;
• cache the control information that indicates that the core network node is to forward the one or more containers, the first identifier, the second identifier, and a third identifier associated with the first network node;
• and
• transmit, to the first network node associated with the third identifier or to the second network node associated with the second identifier, one or more other containers associated with the first identifier.

An integrated access and backhaul (IAB) node for wireless communication, comprising:

• a memory;
• and
• at least one processor coupled to the memory, wherein the IAB node is configured to:
• establish a radio resource control connection with a first central unit of a first network node;
• receive, from the first network node, an indication that the IAB node is to establish an IAB node-to-central unit connection with a second central unit of a second network node via the radio resource control connection between the IAB node and the first network node, wherein the indication is associated with a handover between the first network node and the second network node;
• and
• communicate, with the second network node, via the IAB node-to-central unit connection using the radio resource control connection between the IAB node and the first network node.
