Abstract
A Physical Cell Identity, PCI, conflict avoidance method in a wireless network comprising a first base station controlling a first cell having a first PCI, the method comprising: determining a conflict between the first PCI and a PCI of another cell in the vicinity of the first cell; and activating a second cell having a second PCI, wherein the second PCI is different to the first PCI.

A method for a Central Unit, CU, of an Integrated Access and Backhaul, IAB, donor node, the CU of the IAB donor node controlling an IAB topology comprising a first cell established by a first Distributed Unit, DU, of an IAB node of the IAB topology, the method comprising:
- determining a conflict between a Physical Cell Identity, PCI, of the first cell and a PCI of another cell in the vicinity of the first cell;
- obtaining a new PCI that does not cause a conflict with the PCI of another cell in the vicinity of the first cell;
- and
- instructing the IAB node to activate, by the first DU of the IAB node, a second cell having the new PCI.
