1. A method in a wireless communication system comprising at least one heterogeneous cell having a serving macro cell base station and at least one small cell subtended within a coverage area of the serving macro cell base station, the heterogeneous cell constituting a macro cell for subtended small cells, the method comprising:

  • providing in the macro cell at least one publicly-accessible small cell having a coverage area corresponding to a coverage area of the at least one small cell;

    providing a first communication path between the at least one publicly-accessible small cell and a mobile terminal; and

    providing a second communication path between the serving macro cell base station and the mobile terminal,wherein forward link transmissions to the mobile terminal are performed over one of the first and the second communication paths and reverse link transmissions from the mobile terminal are performed over the other one of the first and the second communication paths based on a distance measured between the publicly-accessible small cell and the serving macro cell base station.
