1. A macro base station (MBS) operating as an enhanced/evolved Node B (eNB) in an LTE network, comprising:

  • an air interface for communicating with users within a macrocell and connecting associated users to a core network;

    processing circuitry configured to identify a number M of the weakest users associated with the MBS according to a defined strength metric, request a list of L preferred pico base stations (PBSs) for offloading from each of the weakest users, offload a weakest user to one of its L preferred PBSs if information received from that PBS indicates that the offloading would result in changes in an overall system utility and a user utility as defined by a specified utility metric that meet one or more specified criteria.
