  • Patent number: 8401479
    Abstract: A system and method for minimizing interference for mobile devices in a communication network that includes a macrocell base station and a femtocell having a base station. The method receives initialization data on a backhaul connection between the femtocell base station and the macrocell base station, and uses that data to configure the femtocell base station transmitting power. The method receives a user equipment identifier from a macrocell user equipment in the communication network, and determines whether the macrocell user equipment is authorized. If authorized, the macrocell user equipment is granted access to the femtocell base station. If unauthorized, user equipment information for the macrocell user equipment received on the backhaul connection is used to adjust the femtocell base station transmitting power to minimize the interference for mobile devices.

  • Patent number: 8285322
    Abstract: A system and method for minimizing interference for mobile devices operating in a communication network that includes a centralized controller and a number of femtocells, each femtocell including a base station. The method calculates a power assignment priority for each femtocell, and determines a priority order of the femtocells, the priority order based on the power assignment priority calculated for each femtocell. The method calculates a power to assign to the base station for each femtocell based on the priority order. The method allocates a first portion of the power assigned to the base station for each femtocell as required for real-time traffic, and a second portion of the power assigned to the base station for each femtocell as required for non-real-time traffic.

  • Patent number: 7848221
    Abstract: Disclosed are a method and system for detecting adjacent channel interference between two systems having neighboring frequencies. The method and system calculates a Fast Fourier Transform (FFT) output for one or more upper and lower frequency side null subcarriers and center data subcarriers of a frequency channel. Power values are calculated for the upper and lower frequency side null subcarriers and the center data subcarriers for use in determining a presence of adjacent channel interference (ACI).
