Abstract
Systems and methodologies are described that facilitate cell search and detection in high interference situations. Heterogeneous network can include a plurality of unplanned femtocell deployments, which can prevent macrocellular UEs from acquiring macrocells. A base station within the network can transmit a low reuse preamble that includes system information, wherein the low reuse preamble is tunneled on a downlink traffic channel such as a physical downlink shared channel. A UE can detect the low reuse preamble and evaluate the preamble to obtain the system information.
