1. A computer-implemented method of mitigating interference using a computing system having processor, memory, and data storage units, the computer-implemented method comprising:

  • detecting, via a serving base station (BS), that a high downlink (DL) signal from a nearby BS is received by a user equipment (UE), the UE being an edge UE located at an edge of a power transmission cell served by the serving BS;

    inferring an uplink (UL) signal of the UE, via the detected high DL signal;

    enabling an interference mitigation algorithm, via the serving BS, wherein enabling the interference mitigation algorithm comprises;

    determining whether middle band resource blocks (RBs) are available, andupon determining whether middle band RBs are available,allocating one or more of the middle band RBs to the edge UE;

    requesting from the UE, an updated DL signal measurement of the nearby BS; and

    disabling the interference mitigation algorithm when the updated DL signal measurement is less than a threshold level.
