A method, an apparatus, and a computer program product for wireless communication are provided in which a switch to a second network is facilitated by increasing a rate of measurement of certain quantities of the second network while in an idle state in a first network. The rate of measurement maybe increased to an integer multiple of a frequency associated with a discontinuous reception cycle configured for the first network.

Dynamic measurement rates to speed up cell reselections

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.

Cell range expansion elasticity control

Techniques for using measurements made by UEs to improve network performance are described. In one aspect, RF parameters of cells may be determined by taking into account mobility of the UEs. Mobility information for the UEs may be determined based on measurement report messages (MRMs) sent by these UEs for handover. RF parameters such as antenna down-tilt, antenna orientation, antenna pattern, and/or pilot power of the cells may be determined based on the mobility information for the UEs. In another aspect, the RF parameters of cells may be dynamically adjusted based on loading conditions of cells. In yet another aspect, the location of a UE may be determined based on an MRM sent by the UE for handover. The MRM may include timing measurements for multiple cells. The location of the UE may be determined based on the timing measurements.
