1. A method of operating a base station for improving data rates in a heterogeneous network which is composed of macro cells and pico cells, and wherein user equipment connects to the network via one of said base station serving a macro cell or a low power node serving said pico cell, comprising the steps of:

  • a) receiving a signal strength indicator from one or more UEs located in said heterogeneous network;

    b) identifying a weak coverage area for a user equipment located in said macro cell according to said signal strength indicator;

    c) identifying the location of said UE within a region of said heterogeneous network when said signal strength indicator is below a certain level; and

    d) directing a beam forming antenna of a base station serving said macro cell where said UE is located towards an area of said cell requiring an improved signal strength.
