1. A cell assignment configuration circuit for a wireless distribution communications system (WDCS) that includes at least two WDCS cells each configured to exchange communications signals with a plurality of remote units, the cell assignment configuration circuit configured to:

  • identify at least one remote unit among the plurality of remote units in the WDCS receiving downlink communications signals potentially transmitted by at least one neighboring cell to the WDCS;

    identify at least one Inter-Cell Interference Coordination (ICIC)-engaged WDCS cell in the WDCS in ICIC with the at least one neighboring cell based on a WDCS cell in the WDCS assigned to the identified at least one remote unit receiving downlink communications signals potentially transmitted by the at least one neighboring cell to the WDCS;

    determine at least one non-ICIC-engaged remote unit assigned to the identified at least one ICIC-engaged WDCS cell not identified as receiving downlink communications signals transmitted by the at least one neighboring cell;

    determine a cell assignment configuration for the WDCS based on reassigning the at least one non-ICIC-engaged remote unit to a non-ICIC-engaged WDCS cell; and

    configure a cell assignment of at least one remote unit in the WDCS based on the determined cell assignment configuration.
