Facilitating assignment of physical cell identifier under technological and operational constraints provided herein. Operations of a system include identifying a first group of network equipment that includes a first relationship status and a second group of network equipment that includes a second relationship status different than the first relationship status. The operations also can include determining a first assignment of first identifiers of a group of identifiers for the first group of network equipment based on a first application of first assignment conflicts. Further, the operations can include determining a second assignment of second identifiers of the group of identifiers for the second group of network equipment based on a second application of second assignment conflicts. In an example, determining of the first assignment of first identifiers includes resolving module-k conflicts among the first group of network equipment.
