    This study uses genetic programming to optimize wireless networks, significantly boosting data speeds and user capacity in heterogeneous cellular networks with enhanced intercell interference coordination.

    Area of Science:

    • Wireless Communication
    • Telecommunications Engineering
    • Computer Science

    Background:

    • Heterogeneous cellular networks (HCNs) utilize macro cells (MCs) and small cells (SCs) sharing the same bandwidth.
    • The Third Generation Partnership Project-Long Term Evolution (3GPP-LTE) framework includes enhanced intercell interference coordination (eICIC) for managing interference between cell tiers.
    • Existing methods for eICIC in HCNs have limitations in optimizing performance.

    Purpose of the Study:

    • To evolve advanced control heuristics for managing interference and optimizing performance in HCNs.
    • To improve the efficiency of enhanced intercell interference coordination (eICIC) within the 3GPP-LTE framework.
    • To enhance data rates and user throughput in wireless networks.

    Main Methods:

  • Grammatical genetic programming was employed to evolve control heuristics.
  • The study focused on optimizing small cell (SC) powers and selection biases.
  • Macro cell (MC) duty cycles and user equipment (UE) scheduling at SCs were also addressed within the eICIC framework.

    • Main Results:

    • The evolved heuristics achieved minimum downlink rates three times higher than a baseline method.
    • Performance was twice as high as a state-of-the-art benchmark.
    • A greater number of user equipments (UEs) received transmissions compared to baseline and benchmark methods.

    Conclusions:

    • The proposed genetic programming approach effectively optimizes eICIC in heterogeneous cellular networks.
    • The evolved heuristics demonstrate significant improvements in downlink rates and user capacity.
    • This research offers a novel and effective method for enhancing wireless network performance.
