CELL RANGE EXPANSION ELASTICITY CONTROL

摘要

In some aspects, a method for carrying out load balancing between cells in a heterogeneous network includes measuring loads within macro clusters in the network. The method additionally includes identifying one or more macro clusters experiencing unbalanced load conditions, and sending balancing indicators to one or more cells in the identified macro cluster(s). In other aspects, a method for carrying out load balancing in a heterogeneous network includes reporting cell loads within a macro cluster, and monitoring for balancing indicators. The method further includes responding to a balancing indicator by iteratively adjusting a value of an individual cell offset for a cell until one or more conditions is satisfied. Example conditions include accomplishment of handover, to or from the cell, of one or more low mobility User Equipment (UE), and making a determination that the value of the individual cell offset has reached a threshold prohibiting further adjustment.

1. A method for carrying out load balancing in a heterogeneous network, comprising:
reporting cell loads within a macro cluster; monitoring for one or more balancing indicators; and responding to a balancing indicator by iteratively adjusting a value of an individual cell offset for a cell until at least one of:
handover, to or from the cell, of one or more low mobility User Equipment (UE) can be accomplished; ora determination is made that the value of the individual cell offset has reached at least one threshold prohibiting further adjustment.
