Network node and method therein for assignment of Physical Cell Identities (PCIs) to Radio Base Stations (RBSs) in a wireless communication network. The method includes determining a most densely located RBS, based on the distances from each RBS to a certain number of other RBSs of the plurality of RBSs. The method further includes, for each RBS, i, for which a PCI is to be assigned: assigning a Secondary Synchronization Signal (SSS) to the RBSi from a set of SSSs, based on a distance from the RBSi to another RBS in the communication network associated with the same SSS, and a number of tiers between the RBSi and, at least, the other RBS. Further, a Primary Synchronization Signal (PSS) is assigned to the RBSi, based on the number of cells associated with the RBSi; and a PCI is assigned to the RBSi, based on the SSS and the PSS. |

1. A method for assignment of Physical Cell Identities, PCIs, performed by a network node in a wireless communication network, said communication network comprising a plurality of Radio Base Stations (RBSs), the method comprising:
determining a most densely located RBS of the plurality of RBSs, based on distances from each RBS to a certain number of other RBSs of the plurality of RBSs; starting from the most densely located RBS: for each RBS, i, for which a PCI is to be assigned, in order of increasing distance from the most densely located RBS: assigning a Secondary Synchronization Signal, SSS, to the RBSi from a set of SSSs, based on a distance from the RBSi to another RBS in the communication network associated with the same SSS, and a number of tiers between the RBSi and, at least, the other RBS; assigning a Primary Synchronization Signal, PSS, to the RBSi, based on the number of cells associated with the RBSi; assigning a PCI to the RBSi, based on the SSS and the PSS; based on the assignment of the PCI to the RBSi, communicating the PCI to the RBSi to control radio frequency signaling transmitted from the RBSi to user equipments within a cell serviced by the RBSi. |
