Indication of a PCI change in a mobile IAB network

Abstract:

An apparatus receives an indication of a Physical Cell Identifier (PCI) change for a serving integrated access and backhaul (IAB) node and uses the new PCI value for receiving communication from the serving IAB node based on the indication of the PCI change. The apparatus may comprise a user equipment (UE) or a mobile termination (MT) of a child IAB node that is served by the IAB node.
