A new approach to generating a probing signal by a cell in a heterogeneous network (HetNet) deployment is proposed. A small cell in the HetNet may be switched off by a base station when the small cell is not needed. The small cell is configured to alternate between an off-state and on-state. The small cell maintains the on-state for a predetermined probing period and maintains the off-state for a predetermined off period. The small cell may switch between the on-state and the off-state periodically. The small cell may be activated during a predetermined off period to transmit data to a user device. |
