Inter-donor cell management in integrated access and backhaul

A method of wireless communication performed by an integrated access and backhaul (IAB) donor, comprising:

• receiving a cell configuration of a distributed unit (DU) of an IAB node, the cell configuration being associated with a second IAB donor,
• wherein the DU is one of a set of DUs of the IAB node, and
• wherein the IAB node has a first signaling connection to a central unit (CU) of a first IAB donor;
• and
• performing one or more operations associated with a context transfer, associated with a child of the IAB node, from the first IAB donor to the second IAB donor based at least in part on the cell configuration.

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

• a memory;
• and
• one or more processors coupled to the memory, the memory and the one or more processors configured to:
• determine a cell configuration of a distributed unit (DU) of the IAB node, the cell configuration being associated with a second IAB donor,
• wherein the DU is one of a set of DUs of the IAB node, and
• wherein the IAB node has a first signaling connection to a central unit (CU) of a first IAB donor;
• and
• provide the cell configuration associated with the second IAB donor.

An integrated access and backhaul (TAB) donor for wireless communication, comprising:

• a memory;
• and
• one or more processors coupled to the memory, the memory and the one or more processors configured to:
• receive a cell configuration of a distributed unit (DU) of an TAB node, the cell configuration being associated with a second TAB donor,
• wherein the DU is one of a set of DUs of the TAB node, and
• wherein the TAB node has a first signaling connection to a central unit (CU) of a first TAB donor;
• and
• perform one or more operations associated with a context transfer, associated with a child of the TAB node, from the first TAB donor to the second TAB donor based at least in part on the cell configuration.
