A wireless communication system and method comprising a HetNet, a serving cell with an associated coverage area, and a plurality of additional low power nodes (LPNs) deployed in one or more clusters of cells within the coverage area. Provided. The LPN transmits an associated discovery signal based on the timing of the associated small cell. The serving cell is configured to determine the cell timing and thus the transmission pattern of the discovery signal, and the serving cell configures the measurement gap such that the discovery signal is transmitted during the measurement gap. The network is adapted to accomplish this across varying degrees of granularity and timing measurement inaccuracies by placing measurement gaps and / or adjusting discovery signal (DS) transmission schemes as appropriate.
