TRIGGERING MIGRATION TO ENABLE INTER-DONOR TOPOLOGY ADAPTATION IN A WIRELESS NETWORK

Abstract:

Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a source integrated access and backhaul (IAB) donor central unit (CU) may transmit, to an IAB node having a first signaling connection with the source IAB donor CU, a trigger to establish a second signaling connection between the IAB node and a target IAB donor CU. The source integrated access may transmit, to the IAB node, transport network layer address information associated with the target IAB donor CU to enable the IAB node to establish the second signaling connection with the target IAB donor CU. The IAB node may transmit, to the target IAB donor CU, a request to establish the second signaling connection with the target IAB donor CU based at least in part on the trigger. Numerous other aspects are provided.
